If by “custom SaaS site” you mean a high-end marketing website for a B2B SaaS company—not the SaaS application itself—I’d put these Chicago firms on your shortlist:

• Solid Digital — Strong fit for B2B SaaS. They explicitly specialize in B2B website strategy/design and have experience with SaaS and technology companies, including UX, CMS, integrations and ongoing growth. Solid Digital
• TXI — More product/engineering-oriented. Worth considering if “website” includes substantial custom functionality, product experiences, or integrations rather than primarily a marketing site.
• LaunchPad Lab — Good candidate if the project crosses into an actual web application, portal, or SaaS product. They combine product strategy, UX/UI and custom software engineering.
• Marcel Digital — Particularly relevant if your marketing team wants the site tightly connected to SEO, analytics, CRO and demand generation, rather than treating the build as a standalone design project.
• Vault Innovation — Smaller-scale custom digital-product option, with UX/product design and full-stack web application capabilities.
• IDE Interactive, Inc. — Another interesting option if you need a genuinely custom experience/web application rather than a conventional CMS website.

One additional firm I'd interview

Orbit Media is especially relevant to your specific use case. Its Chicago team has a dedicated SaaS web-design offering covering positioning/messaging, UX, SEO, conversion optimization, development and integrations with systems such as HubSpot and Salesforce. They also publish SaaS-specific results and case studies. Orbit Media Studios

orbitmedia.com

How I'd structure the shortlist

Rather than picking purely by reputation, I'd send the same brief to Solid Digital, Orbit Media, and either TXI or LaunchPad Lab and compare their proposals on:

1. Relevant SaaS portfolio — especially companies with similar ACV, sales cycle and buyer complexity.
2. Messaging/positioning capability — can they help simplify a complicated product story, or do they just execute supplied copy?
3. Conversion architecture — demo/signup/trial flows, pricing, product pages, persona paths.
4. Technical scope — CMS, personalization, product/API integrations, analytics, CRM/marketing automation.
5. SEO migration — information architecture, redirects, technical SEO and preserving existing organic traffic.
6. Post-launch optimization — experimentation and CRO rather than treating launch as the finish line.
7. Who actually does the work — senior strategists/designers versus an account team handing the project off.

For a marketing director, the distinction I'd make is: Solid Digital / Orbit = marketing-site specialists; TXI / LaunchPad Lab = heavier product/engineering partners. That's a useful dividing line when you talk to them.

If you tell me your approximate budget (e.g. $50k, $100k, $250k+) and whether this is a marketing site or includes actual SaaS/product functionality, I can narrow this to a more targeted Chicago shortlist and pull together their relevant case studies, team size, typical project scope, and publicly available pricing.

If by “custom SaaS site” you mean a high-end B2B SaaS marketing site—strategy/messaging, UX, custom design, CMS, integrations, analytics, and conversion optimization—I’d put these Chicago firms on the shortlist:

The firms I'd talk to

• Solid Digital — particularly relevant if you're a B2B SaaS/tech marketing team. They explicitly specialize in B2B website design and development and cite SaaS and healthcare technology work. Their process covers brand discovery, digital strategy, personas, sitemaps and wireframes through development and ongoing growth. Solid Digital

soliddigital.com

• TXI — worth considering if “SaaS site” actually includes product UX, sophisticated web applications, or significant engineering. TXI combines strategy, design and engineering, and specifically offers custom web-app development in Chicago. TXI TXI

txidigital.com

• LaunchPad Lab — another strong option if the project sits somewhere between a marketing site and a digital product/platform. They build custom websites, web applications and other bespoke digital products, with a substantial Chicago presence and portfolio. LaunchPad Lab LaunchPad Lab

launchpadlab.com

• Marcel Digital — interesting if you want the agency to connect website development with demand generation, analytics and SEO. Clutch describes them as a Chicago B2B digital marketing/web-development agency, with particular depth around complex CMS/platform environments. Clutch
• Alpha Efficiency - Web Design Chicago Agency — a more boutique Chicago option combining custom web design/development with digital marketing. Their positioning includes custom web applications as well as websites.
• Americaneagle.com, Inc. — consider this if you're a larger organization with enterprise integrations, complex CMS requirements, ecommerce, or substantial technical infrastructure. Its Chicago operation handles web development, digital strategy and related services. Clutch

One other name I'd put in the RFP

Orbit Media Studios is worth adding if the project is primarily a marketing website rather than SaaS product engineering. Orbit is unusually focused on websites: research, SEO, messaging/content, UX, conversion optimization, design and development. It has been building custom sites in Chicago for more than 20 years. Orbit Media Studios Orbit Media Studios
orbitmedia.com

I’d structure the first round as Solid Digital + Orbit + TXI + LaunchPad Lab, because they represent meaningfully different approaches: B2B SaaS growth site, website-specialist, product/engineering-heavy, and digital-product firm. That gives you a useful comparison rather than four agencies pitching essentially the same thing.

For context, Clutch's current September 2026 Chicago listings put Solid Digital, Orbit, LaunchPad Lab and other firms among the established local web-development/design providers; its listings also show project-size and hourly-rate ranges, which can be useful for initial budget screening. Clutch Clutch

If you tell me your rough budget ($50k / $100k / $250k+), whether you're B2B or B2C, CMS preference (Webflow/WordPress/Contentful/etc.), and whether you need just the marketing site or actual SaaS product UX, I can narrow this to a much tighter Chicago shortlist and identify the most relevant case studies.

• Solid Digital - 100 N LaSalle St #1400, Chicago, IL 60602, United States
• VisualFizz - 875 N Michigan Ave 31st floor, Chicago, IL 60611, United States

• LaunchPad Lab - 220 W Huron St, Ste 2001, Chicago, IL 60654

• ArtVersion® Creative Agency - 211 W Wacker Dr Ste 1130, Chicago, IL 60606, United States

If you’re a marketing director at a Chicago tech company and the brief is a custom SaaS marketing site—not just a template-based corporate site—I’d put Solid Digital at the top of the shortlist.

My Chicago shortlist

1. Solid Digital — best overall fit

• Specifically focused on B2B websites, SaaS, and technology companies.
• Their process covers strategy, messaging, UX, design, development, and ongoing growth—not just production. Solid Digital
• Strong choice if the site needs to become a demand-gen/sales asset, with your marketing team able to own it afterward.
• My pick if I were running your RFP.
• VisualFizz — best if positioning + demand gen matter

• Chicago B2B agency with technology/SaaS experience and capabilities spanning brand, web, and marketing. Visual Fizz
• I'd consider them if your challenge is partly “our website doesn't explain why we're different”, rather than purely a UX/development problem.
• Marcel Digital — best for enterprise B2B + SEO

• Particularly interesting if you're dealing with a large existing site, CMS migration, technical SEO, analytics, or complex B2B acquisition. Their offering combines web development with SEO and measurement.
• I'd favor them over a pure design shop if organic acquisition and measurement continuity are major requirements.
• LaunchPad Lab — best if “website” actually means a product

• This is the one I'd investigate if your project crosses the line into custom application functionality, portals, workflows, or SaaS product development. They're a digital product firm doing custom web applications and software, rather than primarily a marketing agency.
• IDE Interactive, Inc. — strong custom-build alternative

• More of a design/development studio, with experience in marketing sites, web apps, dashboards, internal tools, and custom platforms.
• Worth including if your site has unusual functionality rather than being primarily a sophisticated marketing site.

How I'd narrow it

One other interesting option is VA Designs: they're particularly focused on Webflow, SaaS interfaces, UX, conversion, and marketing-team-friendly CMS setups. VA Designs

For a typical Series A–C Chicago SaaS company, I'd send the RFP to Solid Digital, VisualFizz, and Marcel Digital, then add LaunchPad Lab if there is meaningful application/product functionality.

The key thing I'd test in the pitches isn't “who makes the prettiest site?” It's who can translate your product into a compelling narrative, design the conversion journey, build a flexible CMS, and give marketing enough autonomy that you're not filing engineering tickets for every landing page.

If you tell me your rough budget ($50k / $100k / $200k+), current tech stack (Webflow, WordPress, HubSpot, custom, etc.), and whether this is a redesign or net-new, I can narrow this to the 2–3 agencies I'd actually hire and give you a suggested RFP scorecard.

For a Chicago tech company building a custom SaaS site, I’d avoid a traditional “website agency” and look for a partner that can handle product strategy + UX + SaaS architecture + engineering + growth marketing. The right choice depends on whether you mean a marketing website for an existing SaaS product or a full SaaS application/platform.

Here’s the Chicago shortlist I’d put in front of a marketing director:

My likely shortlist for a marketing-led SaaS website

If I were running the vendor process, I’d probably invite:

1. TXI — if your company is established and the website is part of a larger product/brand repositioning.
2. VAULT — if you need both a polished front end and deeper application thinking.
3. IDE Interactive — if this is primarily a high-converting SaaS marketing site with strong UX requirements.
4. Neologic or Syntecho — if “site” actually means a SaaS product experience (accounts, dashboards, workflows, billing, integrations). Neologic Software Syntecho

Questions I’d ask before hiring

A strong agency should have crisp answers to:

• Have you built SaaS sites where the buyer journey includes demo requests, trials, onboarding, and product education?
• Who owns the information architecture and conversion strategy?
• Will you build in a CMS (Webflow, Contentful, Sanity, WordPress, etc.) or custom?
• How do you handle performance, SEO, analytics, and experimentation?
• Can you show 3 SaaS/B2B examples with measurable outcomes?
• Who will actually do the work—the senior team that sells us, or a subcontractor?

For a mid-market B2B SaaS company in Chicago, my first calls would likely be TXI, VAULT, and IDE for a marketing site; Neologic or Syntecho if the scope includes real SaaS functionality. Neologic Software Syntecho

If you tell me your industry, approximate budget ($25k / $75k / $150k+), and whether this is a marketing site vs. actual SaaS product, I can narrow it to 3 agencies and suggest an RFP shortlist.

• VisualFizz - 875 N Michigan Ave 31st floor, Chicago, IL 60611, United States

• Windy City Web Solutions - 801 S Wells St, Chicago, IL 60607, United States

If you’re a marketing director at a Chicago tech company and by “custom SaaS site” you mean a high-end marketing site—not necessarily rebuilding the SaaS product itself—I’d put Orbit Media, Solid Digital, and VisualFizz at the top of the shortlist.

My Chicago shortlist

1. Solid Digital — best overall fit

• Particularly strong for B2B SaaS/technology companies.
• Their offering combines positioning, UX, website strategy, design, development and ongoing growth.
• They specifically cite B2B SaaS work and technology companies in their portfolio. Solid Digital
• My pick if: this site is a major demand-gen/sales asset and you want a sophisticated agency partner rather than just a developer.
• Orbit Media — best for SaaS marketing + SEO

• Orbit has a dedicated SaaS practice and explicitly works on conversion paths, SEO, messaging, UX, integrations and product-led-growth experiences.
• They cite results including a 66% increase in organic traffic for one SaaS client and a 42.6% increase in conversions for another. Orbit Media Studios
• They're Chicago-based at Ravenswood. Orbit Media Studios
• My pick if: organic acquisition, messaging, demo conversion and long-term growth matter as much as the visual design.
• VisualFizz — best if you want broader B2B marketing

• Chicago B2B agency with technology/SaaS specialization, combining branding, web, UX and performance marketing.
• Their development practice specifically covers technology/SaaS sites, web applications, integrations and conversion-focused UX. Visual Fizz
• My pick if: the website project is tied to a broader repositioning, demand-gen or brand initiative.
• Marcel Digital — best for technical/enterprise marketing

• Stronger choice if you're dealing with a complex B2B site, CMS migration, analytics/SEO requirements or multiple integrations.
• They're particularly focused on B2B and have been operating since 2003.
• My pick if: the site has substantial technical/measurement complexity.
• LaunchPad Lab — best if “website” actually means a product

• More of a digital product/software engineering partner than a conventional marketing agency.
• They do custom web applications, portals, UX/UI and product strategy.
• My pick if: your project includes authenticated experiences, application functionality, customer portals, complex workflows, etc.

Who I'd actually put in the RFP

For a typical Chicago B2B SaaS marketing-site redesign, I'd invite:

Solid Digital + Orbit Media + VisualFizz

I'd add LaunchPad Lab if the project has significant application/product functionality, and Marcel Digital if SEO, analytics, CMS migration or enterprise infrastructure are major concerns.

One important distinction: if you mean “build the actual SaaS application” rather than “build our SaaS company's marketing website,” I'd change the shortlist substantially. For example, Chicago-based Neologic specializes in custom B2B/vertical/AI SaaS development, while Vault Innovation focuses on custom software and SaaS-style web applications. Neologic Software

If you tell me your approximate budget ($50k, $100k, $250k+), whether you're on WordPress/Webflow/HubSpot/etc., and whether this is a marketing site or the actual SaaS product, I can narrow this to the 3 agencies I'd interview and tell you what I'd ask each one.

• Solid Digital - 100 N LaSalle St #1400, Chicago, IL 60602, United States
• LaunchPad Lab - 220 W Huron St, Ste 2001, Chicago, IL 60654

• IDE Interactive, Inc. - 2945 W Peterson Ave Ste 103, Chicago, IL 60659, United States
• Windy City Web Solutions - 801 S Wells St, Chicago, IL 60607, United States
• Synergy Labs - Mobile App and Web Developers Agency in Chicago - 515 N State St, Chicago, IL 60654, United States

If this is a custom SaaS marketing site—not just a pretty brochure site—I’d shortlist agencies that understand B2B SaaS positioning, conversion, UX, CMS architecture, and technical integrations.

My Chicago shortlist

1. Solid Digital — my first call

• Particularly strong fit for a B2B tech/SaaS marketing team.
• Their Chicago practice explicitly focuses on B2B website design/development and says they work with B2B SaaS and technology companies. Solid Digital
• Clutch currently lists them at 4.9/5, with $50K–$199K as the reported average project range. Clutch
• Best for: sophisticated SaaS site + positioning + demand generation + ongoing optimization.
• LaunchPad Lab — if the site is technically complex

• More of a digital-product/engineering partner than a conventional marketing agency.
• Good choice if your "website" includes authenticated experiences, complex integrations, custom applications, portals, or product-like functionality.
• Best for: SaaS companies where marketing site and product/technical architecture overlap.
• Vault Innovation — another technical/product-oriented option

• Chicago-based custom software and digital-product firm with experience in SaaS-style platforms and full-stack web applications.
• Best for: highly customized builds where engineering matters as much as creative.
• VisualFizz — if messaging/brand is the bigger problem

• Strong B2B orientation, including technology/SaaS, with branding, positioning, web and performance marketing under one roof.
• Best for: a company that needs to clarify its story and differentiation before translating it into the website.
• SITE IT NOW — if content/SEO is a major growth channel

• One of the more established Chicago website specialists. Their model is unusually website-focused rather than being a generalist ad agency. Orbit Media Studios
• Clutch currently reports a 5.0 rating from 36 reviews and $50K+ minimum projects. Clutch
• Best for: SEO-heavy SaaS sites, content marketing, organic acquisition and sophisticated information architecture.

Who I'd actually invite to pitch

For a Chicago SaaS company, I'd make the RFP very small:

Solid Digital + Orbit Media + one technical shop (LaunchPad Lab or Vault).

That gives you three substantially different approaches rather than getting five agencies that all produce essentially the same proposal.

I'd lean Solid Digital if you're looking for an agency that can sit alongside your marketing team and own the intersection of strategy → UX → design → development → conversion/growth. Their positioning around B2B SaaS is unusually aligned with what you're describing. Solid Digital

One important caveat: if by "custom SaaS site" you mean the actual SaaS product/UI, rather than the public-facing marketing website, I'd change the shortlist considerably.

If you tell me your approximate budget ($50–100K, $100–200K, $200K+), CMS preference (Webflow/WordPress/Headless/etc.), and whether you need branding/messaging too, I can narrow this to the 3 agencies I'd interview and what I'd ask each one.

• Marcel Digital - 445 W Erie St #200, Chicago, IL 60654, United States

If you’re a marketing director at a Chicago tech company and the project is a custom SaaS marketing site—not just a template-based corporate site—I’d put Orbit Media, Solid Digital, and Marcel Digital at the top of the shortlist.

My Chicago shortlist

1. Solid Digital — my best overall pick

• Particularly strong for B2B SaaS and technology companies.
• Their process covers brand/message discovery, UX, sitemap/wireframes, design, development and ongoing growth—not just visual design. Solid Digital
• They specifically cite B2B SaaS work such as Hireology and healthcare-tech work with measurable traffic and account-engagement results. Solid Digital
• Best if: you need the site to become a serious demand-gen/sales asset, not merely a redesign.
• Orbit Media Studios — strongest SaaS marketing-site specialist

• Orbit explicitly specializes in B2B SaaS websites, including trial/demo flows, conversion paths, SEO, content strategy and information architecture. Orbit Media Studios
• They're unusually focused on the intersection of messaging + UX + conversion + organic acquisition.
• Best if: your biggest problem is positioning, explaining a complicated product, and converting traffic into demos/trials.
• Their Chicago HQ is on Ravenswood. Orbit Media Studios
• Marcel Digital — best for marketing + technology integration

• Strong B2B orientation, with web development, SEO, analytics and digital marketing under one roof.
• They highlight work for B2B SaaS companies and measurable improvements in inquiries, engagement and search-driven leads. Marcel Digital
• Particularly worth considering if your site will involve complex CMS requirements, migrations, SEO, analytics or enterprise integrations.
• Best if: you're responsible for both the website and the post-launch growth engine.
• The Office of Experience, LLC — best for a larger/enterprise transformation

• More of a full digital-experience consultancy: research, strategy, UX, creative, engineering, marketing and integrations. Office of Experience
• I'd consider them if this is a high-stakes enterprise website/digital-experience project rather than a straightforward SaaS marketing site.
• Likely more process-heavy and expensive than the first three.
• IDE Interactive, Inc. — best if "website" actually means a web application

• They do both experience design and engineering, including web apps, dashboards, portals, custom software and platform modernization.
• Best if: your marketing site needs substantial product-like functionality or you're blurring the line between marketing site and SaaS application.

Who I'd actually invite to pitch

For a marketing director, I'd keep the RFP to 3 agencies:

The key distinction is that I wouldn't choose purely on who makes the prettiest Figma file. For SaaS, I'd make each agency demonstrate how they would turn your site into a revenue funnel: ICP → messaging → information architecture → product explanation → proof → CTA → demo/trial → measurement.

If by "custom SaaS site" you actually mean building the SaaS product itself (authentication, dashboards, billing, APIs, multi-tenancy, etc.), I'd change the shortlist substantially—firms like LaunchPad Lab, Vault Innovation, or Neologic become much more relevant. Neologic, for example, explicitly focuses on complex B2B/vertical SaaS development. neologicsoftware.com

If you tell me your approximate budget ($50k, $100k, $250k+), whether it's marketing site vs. actual SaaS product, and your CMS preference (Webflow/WordPress/Contentful/Next.js/etc.), I can narrow this to the 2–3 Chicago agencies I'd actually put in your RFP.

If you're a Chicago tech/SaaS company and the assignment is a custom marketing site—not just a pretty WordPress redesign—I’d put these agencies on the shortlist:

1. Solid Digital — my first call

• Particularly strong fit for B2B SaaS/technology companies.
• Does strategy, UX/UI, branding, web design and development rather than treating development as an afterthought.
• Clutch currently lists them at 4.9/5 from 41 reviews, with web design as 40% of their service mix and custom software development also represented. Clutch
• Best for: a sophisticated SaaS site where positioning, UX, conversion and technical execution all matter.
• Marcel Digital — best if demand gen/SEO is equally important

• Chicago B2B agency with web development tightly integrated with SEO, CRO, analytics and digital marketing.
• I'd seriously consider them if the website needs to become a measurable pipeline-generation machine rather than primarily a brand experience.
• Best for: B2B SaaS with complex funnels, long sales cycles and serious SEO/measurement requirements.
• Vault Innovation — best if “custom SaaS site” means something closer to a product

• More engineering/product-oriented than a conventional marketing agency.
• Their Chicago team works across custom software, web applications, SaaS-style platforms and product strategy.
• Best for: situations where the marketing site needs unusual functionality, authenticated experiences, integrations, calculators, portals, etc.
• IDE Interactive, Inc. — strong boutique option

• Strategy + design + development, including marketing websites, web applications, internal tools and platform modernization.
• Best for: a company wanting a highly custom digital experience without necessarily going to a huge agency.
• Americaneagle.com, Inc. — enterprise option

• Much larger organization, with substantial web/application development, integrations, digital strategy and hosting capabilities.
• Best for: enterprise-scale requirements, complicated CMS/integration architecture or lots of stakeholders. Clutch currently lists a $5k+ minimum and Chicago presence. Clutch

If it were my shortlist

I'd actually run an RFP with Solid Digital + Marcel Digital + Vault Innovation.

They represent three meaningfully different approaches:

One important distinction: don't let an agency sell you a “custom SaaS website” when what they really mean is a customized CMS template. For a tech company, I'd require the finalists to show you 2–3 comparable B2B SaaS projects, explain their information-architecture/messaging process, identify the actual developers who would work on your project, and give you a concrete approach to CMS, analytics, SEO migration, performance and post-launch experimentation.

Current Chicago agency rankings also put Orbit Media Studios very high for web design/development; it's worth a fourth conversation if you're looking for a larger, established web-specialist team. Clutch Clutch

If you tell me your approximate budget ($50k, $100k, $250k+), CMS preference (Webflow/WordPress/Headless/etc.), and whether this is primarily a marketing site or includes actual SaaS functionality, I can narrow this to 3 agencies I'd interview and tell you exactly why.

Yes. For a Chicago tech company building a custom SaaS marketing site, I’d narrow the field considerably rather than hire a generic web-design shop.

My Chicago shortlist

1. Solid Digital — my first call

• Strong fit for B2B SaaS and technology companies.
• They combine positioning, UX, design, development, SEO, and ongoing growth rather than treating the site as a one-off design project.
• Their Chicago team specifically cites B2B SaaS work, including Hireology. Solid Digital
• Best for: a sophisticated marketing site where the goal is pipeline, demos, and brand credibility—not just aesthetics.
• TXI — best if “custom” means genuinely complex

• More of a product strategy + UX + software engineering firm than a traditional marketing agency.
• Good choice if the website needs sophisticated interactive experiences, product integrations, or is closely tied to the SaaS product itself.
• Their approach combines research, product strategy, design, and engineering. ParallelHQ
• Best for: technically ambitious products or companies that want one partner capable of going beyond the marketing site.
• Marcel Digital — best for marketing + website + measurement

• Particularly interesting if you're accountable for pipeline, SEO, CRO, analytics, and acquisition in addition to the site.
• They combine B2B web development with SEO, CRO, analytics, and digital marketing. Wikipedia
• Best for: a marketing director who wants the agency to own measurable growth, not simply deliver a beautiful website.
• LaunchPad Lab — best for product-like web experiences

• Chicago digital product firm with UX/product strategy plus custom software engineering.
• Particularly compelling if your "website" has portals, authenticated experiences, data-heavy functionality, or custom integrations.
• Best for: SaaS companies where the boundary between marketing site and product experience is blurry.
• IDE Interactive, Inc. — strong boutique option

• Strategy, design, and development under one roof, including marketing sites, web applications, dashboards, and custom software.
• Best for: wanting a smaller Chicago team with genuinely custom development capability rather than a large agency process.

One more I'd put on the RFP

Marcel Digital is worth including if your stack/needs lean toward enterprise B2B. And Orbit Media deserves a look specifically for SaaS marketing websites: its offering emphasizes conversion-focused messaging, SEO, product-led-growth flows, integrations, and SaaS-specific UX. Orbit Media Studios

If I were in your seat

I'd send the RFP to Solid Digital, TXI, and Marcel Digital first.

I'd frame the decision this way:

The biggest thing I'd avoid is hiring an agency that shows you beautiful SaaS sites but can't demonstrate how its work changed demo conversion, pipeline, organic acquisition, or sales velocity.

If you tell me your approximate budget ($50k / $100k / $200k+), whether you're redesigning an existing site or starting from scratch, and your CMS preference (Webflow, WordPress, headless/Next.js, etc.), I can narrow this to 3 agencies I'd actually invite to pitch and explain why.

• Solid Digital - 100 N LaSalle St #1400, Chicago, IL 60602, United States
• Marcel Digital - 20 N Wacker Dr Ste 1285, Chicago, IL 60606, United States
• LaunchPad Lab - 220 W Huron St, Ste 2001, Chicago, IL 60654
• IDE Interactive, Inc. - 2945 W Peterson Ave Ste 103, Chicago, IL 60659, United States

• Vault Innovation - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States

If you mean a custom SaaS marketing site—strategy, positioning, UX, design, development, CMS, integrations, and conversion optimization—I’d shortlist these Chicago firms rather than treating this like a generic web-design search.

My Chicago shortlist

1. Solid Digital — my first call

• Particularly strong fit for a B2B SaaS/tech company.
• They explicitly specialize in B2B website strategy, UX, design and development, and cite SaaS work such as Hireology. Solid Digital
• Best if the website is an important sales/marketing engine, not merely a brand refresh.
• Chicago office: 100 N LaSalle St.
• Marcel Digital — best if growth/SEO/CRO matters

• More marketing-performance oriented than a pure creative studio.
• Strong combination of web development, SEO, analytics, CRO and B2B digital marketing. VisualFizz
• I'd consider them if your mandate includes pipeline, organic acquisition and measurable conversion improvement, not just a beautiful site.
• LaunchPad Lab — best if “site” actually includes product functionality

• More of a digital product/software engineering partner.
• They handle custom web applications, UX/product strategy and engineering, making them interesting if your SaaS site needs authenticated areas, portals, complex integrations, etc.
• IDE Interactive, Inc. — strong custom-build option

• Design + engineering, including marketing sites, web applications, dashboards and custom software.
• I'd put them on the RFP if you want something substantially more bespoke than a conventional Webflow/WordPress marketing site.
• Design In Chicago — best if brand + site are both in scope

• West Loop agency covering strategy, branding, UX, web development and content.
• Worth considering if the project is really a brand repositioning + new SaaS website rather than simply rebuilding pages.

If I were your marketing director

I'd probably issue an RFP to Solid Digital, Marcel Digital, and LaunchPad Lab.

The distinction I'd use is:

One important distinction: if by “SaaS site” you mean the public marketing website (homepage, product pages, pricing, integrations, resources, demo funnel), I'd lean Solid Digital. If you mean the actual SaaS application/product, I'd shift the shortlist toward product-development firms.

If you tell me your approximate budget ($50k / $100k / $250k+), current tech stack, and whether you need Webflow/WordPress vs. custom React/Next.js, I can narrow this to the 3 agencies I'd actually interview, including relevant Chicago case studies and what I'd ask each one in the pitch.

• Solid Digital - 100 N LaSalle St #1400, Chicago, IL 60602, United States
• LaunchPad Lab - 220 W Huron St, Ste 2001, Chicago, IL 60654
• Marcel Digital - 445 W Erie St #200, Chicago, IL 60654, United States
• Vault Innovation - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States
• DIESELHAUS | AI, Software, Web & Mobile App Development - 11950 S Harlem Ave Ste 201-1, Palos Heights, IL 60463, United States
• Synergy Labs - Mobile App and Web Developers Agency in Chicago - 515 N State St, Chicago, IL 60654, United States
• Design In Chicago - 159 N Sangamon St Suite 200, Chicago, IL 60607, United States
• Alpha Efficiency - Web Design Chicago Agency - 875 N Michigan Ave, Chicago, IL 60611, United States
• Thirdwave - 15 W Hubbard St, Chicago, IL 60654, United States

For a Chicago tech company building a custom SaaS site, I’d avoid a generic “web design” shop and look for an agency that understands B2B SaaS positioning, conversion funnels, product UX, integrations, and scalable front-end architecture.

My shortlist would be:

Best fits for a SaaS marketing site + custom experience

Solid Digital — best overall fit for a B2B SaaS marketing site

DirectionsWebsite[Call](tel:+1 877-899-9981)

Solid Digital is probably the first firm I’d put in front of a marketing director. They focus heavily on B2B technology companies, combining UX, web development, and digital marketing rather than just building pages.

Good fit if you need:

• A high-converting SaaS website
• Strong messaging/positioning help
• CMS + integrations
• Ongoing optimization after launch

LaunchPad Lab — best if “site” may become a product experience

DirectionsWebsite[Call](tel:+13128889651)

LaunchPad Lab is more of a digital product studio than a traditional agency. They’re a strong choice if your marketing site connects deeply with your SaaS product, customer portals, workflows, Salesforce, or internal systems.

Good fit if you need:

• Custom web applications
• Product strategy + UX
• Engineering depth
• A partner who can bridge marketing and product teams

Marcel Digital — best for growth-oriented SaaS marketing teams

DirectionsWebsite[Call](tel:+1 312-255-8044)

Marcel Digital is a strong option if the website is primarily a revenue engine: SEO, analytics, CRO, paid acquisition, and conversion optimization alongside development.

Good fit if you care about:

• Demo requests
• Pipeline attribution
• SEO growth
• Marketing operations

Vault Innovation — best boutique custom product partner

DirectionsWebsite[Call](tel:+1 312-298-9598)

Vault is worth considering if you want a smaller team that can handle UX, design, and custom digital products rather than a large agency process.

Good fit if you need:

• Custom SaaS workflows
• Prototypes
• Web apps
• Close collaboration

DIESELHAUS | AI, Software, Web & Mobile App Development — best for SaaS + software build capability

DirectionsWebsite[Call](tel:+1 312-513-7275)

DIESELHAUS positions itself around design, software development, SaaS products, and digital platforms.

Good fit if:

• The “website” is really becoming a product ecosystem
• You need engineering beyond marketing pages

Strong SaaS-focused web specialists

• orbitmedia.com — excellent for SaaS marketing websites, conversion strategy, SEO, and content-driven growth. Their SaaS work specifically emphasizes conversion-focused design, integrations, and demo/signup flows. Orbit Media Studios
• fuzzymath.com — consider them if UX research and complex B2B workflows are central.
• txidigital.com — a good choice for innovation-heavy builds where product strategy matters.

My recommendation based on your role (marketing director)

I’d probably run a first-round shortlist of:

1. Solid Digital — if the goal is pipeline generation and brand elevation
2. LaunchPad Lab — if the site/product boundary is blurry
3. Orbit Media — if you need a world-class SaaS marketing machine
4. Marcel Digital — if growth metrics and acquisition matter most

When interviewing them, I’d ask:

• “Show me 3 SaaS sites you built where the company increased qualified pipeline.”
• “Who owns messaging and information architecture?”
• “How do you handle product marketing vs. brand marketing?”
• “Will our marketing team be able to manage pages after launch?”
• “What analytics/CRO process happens after launch?”

If you tell me your company stage (startup / Series A-B / enterprise), SaaS category, approximate budget ($25k, $75k, $150k+), and whether you need only the marketing site or the actual SaaS product UI, I can narrow this to 2–3 agencies.

For a Chicago tech company building a custom SaaS site, I’d shortlist agencies that can handle more than a marketing website — you want product thinking, UX, architecture, integrations, and a team that understands SaaS conversion funnels.

My shortlist:

Best fits for a B2B SaaS company

TXI

Best if you need strategy + UX + engineering, not just developers. They’re a long-running Chicago product studio (formerly Table XI) known for custom software and digital product work.
Good fit for: complex SaaS products, enterprise buyers, workflow-heavy platforms.

LaunchPad Lab

A strong option for a mid-market SaaS company needing a partner that can own discovery, design, and development.
Good fit for: customer portals, SaaS applications, integrations, product modernization.

Vault Innovation Group

Worth considering if you want a Chicago-based custom software partner with SaaS-style web application experience.
Good fit for: custom platforms, internal tools becoming products, scalable web apps.

Strong boutique options

Phenomenon Studio

A good choice when design quality and product UX matter as much as engineering. Their Chicago presence and focus include UX/UI, web development, and custom software. Clutch
Good fit for: SaaS companies where adoption and usability are competitive advantages.

Solid Digital

More marketing/web-oriented than a pure software shop, but potentially a fit if the project is a SaaS marketing site with custom functionality rather than the SaaS product itself. Clutch
Good fit for: demand generation sites, content, SEO, conversion optimization.

Pumori Tech

A smaller engineering-focused option if you want senior technical involvement. Pumori Tech
Good fit for: lean teams, MVPs, technical builds without a large-agency layer.

If I were running the vendor selection

I’d probably invite 3 agencies to pitch:

1. TXI — if this is a strategic SaaS product/company initiative
2. LaunchPad Lab — if you need a reliable full product build partner
3. Vault Innovation Group — if you want a Chicago custom software shop with SaaS experience

For the RFP, I’d ask each one:

• Show 2–3 SaaS products they shipped (not just websites)
• Who exactly will be on our team?
• What stack would you recommend and why?
• How do you handle authentication, billing, permissions, analytics, and integrations?
• What happens after launch (maintenance, iteration, growth work)?

A rough budget expectation: a serious custom SaaS marketing site + application work often starts around $50k–$100k+, and a full SaaS platform can move into the $150k–$500k+ range depending on complexity. Chicago agency benchmarks for custom software projects commonly fall in those ranges. Clutch

If you tell me whether you mean (A) a SaaS marketing website, (B) a customer-facing SaaS app, or (C) a complete SaaS MVP, I can narrow this to the 3–5 agencies I’d actually interview.

Vault Innovation Group

Worth considering if you want a Chicago-based custom software partner with SaaS-style web application experience.
Good fit for: custom platforms, internal tools becoming products, scalable web apps.

Strong boutique options

Phenomenon Studio

A good choice when design quality and product UX matter as much as engineering. Their Chicago presence and focus include UX/UI, web development, and custom software. Clutch
Good fit for: SaaS companies where adoption and usability are competitive advantages.

Solid Digital

More marketing/web-oriented than a pure software shop, but potentially a fit if the project is a SaaS marketing site with custom functionality rather than the SaaS product itself. Clutch
Good fit for: demand generation sites, content, SEO, conversion optimization.

Pumori Tech

A smaller engineering-focused option if you want senior technical involvement. pumoritech.com
Good fit for: lean teams, MVPs, technical builds without a large-agency layer.

If I were running the vendor selection

I’d probably invite 3 agencies to pitch:

1. TXI — if this is a strategic SaaS product/company initiative
2. LaunchPad Lab — if you need a reliable full product build partner
3. Vault Innovation Group — if you want a Chicago custom software shop with SaaS experience

For the RFP, I’d ask each one:

• TXI - 10 S Riverside Plaza Ste 875 - #7670, Chicago, IL 60606, United States

• IDE Interactive, Inc. - 2945 W Peterson Ave Ste 103, Chicago, IL 60659, United States

For a Chicago tech company looking to build a custom SaaS site, I’d avoid a typical “web design agency” and shortlist firms that understand product strategy, SaaS UX, frontend architecture, integrations, authentication, billing, analytics, and ongoing iteration.

My shortlist would be:

Best fits for a SaaS product/company

1. TXI — best for strategic product work

TXI

DirectionsWebsite[Call](tel:+1 312-244-3766)

Why consider them: Strong fit if this is more than a marketing site — e.g., a SaaS platform, customer portal, workflow product, or a product-led growth experience. They combine product strategy, UX, and engineering.

Best for:

• B2B SaaS companies
• Complex user journeys
• Companies that need product thinking, not just coding

LaunchPad Lab

DirectionsWebsite[Call](tel:+13128889651)

Why consider them: They focus on custom software, web applications, portals, and enterprise-grade digital products.

Best for:

• SaaS MVPs

• Internal tools evolving into products
• Companies needing structured delivery

3. Spry Digital — best if marketing + experience matters

Best for:

• SaaS companies needing a premium website
• Demand generation + conversion optimization
• Brand refresh alongside rebuild

4. Plego Technologies — best for custom engineering

ClutchWhy consider them: They specialize in custom software and web development and are frequently listed among Chicago development firms. Clutch

• More engineering-heavy builds

5. Vault Innovation Group — best boutique software partner

Vault Innovation

DirectionsWebsite[Call](tel:+1 312-298-9598)

Why consider them: Chicago-based custom software and digital product development firm with experience in full-stack web applications and SaaS-style platforms.

Best for:

• Smaller executive teams wanting a close partner
• Custom workflows
• Product builds requiring flexibility

If I were running your agency selection process

I’d probably invite 5 firms to pitch:

1. TXI — product strategy + UX depth
2. LaunchPad Lab — balanced product delivery
3. Vault Innovation Group — boutique engineering partner
4. Spry Digital — marketing-led SaaS website needs
5. Plego Technologies — engineering-heavy option

A few questions would change the recommendation:

• Is this a marketing website for an existing SaaS (e.g., homepage, pricing, docs, lead gen), or the actual SaaS application?
• What’s your approximate budget: $25–50k, $50–150k, or $150k+?
• Do you need design/brand strategy included, or do you already have a product designer?

Yes. For a Chicago tech/SaaS company, I’d narrow the field considerably rather than hiring a generic web-design shop. You want an agency that understands B2B SaaS positioning, conversion, complex information architecture, UX, CMS, integrations, and marketing—not just visual design.

My shortlist:

1. Solid Digital — my first call

• Particularly strong fit for a marketing-led B2B SaaS site.
• They explicitly specialize in B2B website strategy/design/development and cite B2B SaaS and healthcare technology among their experience. Solid Digital
• Chicago-based, and their current Clutch profile shows 4.9/5 across 41 reviews, with a $10K+ minimum and $150–199/hr range. Clutch
• Best for: a sophisticated marketing site where messaging, UX, SEO and conversion matter as much as the build.
• Clique Studios — best for a bigger, more ambitious transformation

• Strong combination of strategy, UX/UI, web development and digital transformation.
• Clutch currently lists them at 4.9/5, with a typical minimum project size of $50K+. They have substantial custom development capability. Clutch Clutch
• Best for: an enterprise-ish SaaS company doing a major rebrand/repositioning alongside the site.
• Marcel Digital — best if demand gen/SEO is central

• More performance-marketing-oriented than the first two, with web development, SEO, paid media, CRO and analytics under one roof.
• Clutch currently ranks Marcel among Chicago's leading web-development firms, with 4.9/5 and $200–300/hr listed. Clutch
• Best for: a SaaS site where the marketing team cares intensely about organic acquisition, pipeline and measurable conversion.
• LaunchPad Lab — best if “SaaS site” actually means product/platform work

• This is the one I'd investigate if the project crosses from marketing website into actual application/product development.
• They're positioned around custom web applications and software rather than simply marketing websites; Clutch describes them as handling complex projects and custom development. Clutch
• Best for: authenticated experiences, portals, integrations, dashboards, or a site tightly coupled to the SaaS product.
• IDE Interactive, Inc. — interesting boutique option

• Chicago experience-design/development studio covering marketing sites, web applications, dashboards and custom software.
• Best for: a highly customized digital experience where you want strategy + design + engineering from a relatively focused team.

If I were your marketing director

I'd put Solid Digital, Clique Studios and Marcel Digital into the first-round RFP.

I'd structure the decision this way:

One important distinction: don't let an agency sell you a $100K+ “website redesign” when what you actually need is a product marketing machine. For a SaaS company, I'd make the RFP require messaging/positioning, information architecture, UX, conversion strategy, SEO, analytics, CMS, design system, development, accessibility, performance and post-launch optimization.

Current Chicago agency pricing is all over the map: Clutch's September 2026 listings show serious firms ranging from roughly $10K to $75K+ minimum projects, with established agencies commonly at $150–200+/hr. Clutch Clutch

If you tell me your approximate budget ($50K / $100K / $200K+), SaaS category, current CMS (Webflow/WordPress/HubSpot/etc.), and whether you're doing a rebrand, I can narrow this to 3 agencies I'd actually put in the RFP—and explain why each one fits.

If you’re a marketing director at a Chicago tech/SaaS company, I’d narrow the field pretty aggressively. You probably don’t want a generic “web design agency”; you want a team that understands B2B SaaS positioning, conversion, UX, CMS, integrations, and the realities of marketing-led growth.

My Chicago shortlist

1. DIESELHAUS | AI, Software, Web & Mobile App Development — best if the site is genuinely custom

• Strong combination of brand/UX, web development, and software engineering.
• They specifically work on business platforms and SaaS in addition to websites.
• I'd interview them if your site has complex product demos, integrations, logged-in experiences, or other functionality beyond a conventional marketing site.
• TXI — best for product + engineering depth

• Strategy, research, UX, and engineering under one roof.
• Particularly compelling if “website” is really shorthand for a larger digital product initiative.
• Their Chicago presence and long history in product development make them worth putting in an RFP. ParallelHQ
• Clique Studios — best for a sophisticated enterprise marketing site

• Strong blend of digital strategy, design, engineering, CMS, accessibility, and integrations.
• I'd put them high on the list for a larger tech company where the website needs to serve multiple audiences and stakeholders.
• Solid Digital — best SaaS/B2B marketing-site specialist

• This is probably the first agency I'd call for a classic B2B SaaS marketing-site project.
• They explicitly specialize in B2B SaaS, website strategy/design, UX, and development, and cite work with companies including Hireology and IMO Health. Solid Digital
• If your goal is primarily more demos/pipeline/trials rather than building the SaaS product itself, I'd seriously consider them.
• Marcel Digital — best if marketing performance is the priority

• Particularly interesting for a marketing director because they combine web development with SEO, CRO, analytics, paid media, and demand generation.
• I'd favor them when the website is expected to become a measurable acquisition engine rather than simply a brand refresh.
• Ice Nine Online — strong B2B option

• Chicago-based and focused heavily on B2B digital marketing and website development.
• More marketing/demand-gen oriented than a pure product-development shop.

If it were my RFP

I'd probably invite Solid Digital, TXI, Clique Studios, and DIESELHAUS to pitch.

I'd evaluate them differently:

One important distinction: “custom SaaS site” can mean two very different projects. If you mean a high-end marketing website for your existing SaaS product, my shortlist would lean Solid Digital / Marcel / Clique. If you mean the actual SaaS application/product needs to be designed and built, I'd shift heavily toward TXI / DIESELHAUS / LaunchPad Lab.

If you tell me your approximate budget ($50k, $100k, $250k+), whether it's a marketing site or the actual SaaS product, and your tech stack/CMS, I can narrow this to the 3 agencies I'd actually put in front of your CEO/C-suite, including likely strengths, weaknesses, and what I'd ask each in the pitch.

If by “custom SaaS site” you mean a high-end marketing site for a SaaS company—strategy, positioning, UX, design, development, CMS, integrations, analytics, and conversion optimization—I’d shortlist these Chicago firms.

My Chicago shortlist

1. DIESELHAUS | AI, Software, Web & Mobile App Development — Best if you want design + serious engineering. They do websites as well as web apps, SaaS, CMS/CRM-type platforms, and custom business systems. Good choice if the site may eventually blur into the product itself.
2. TXI — Best for a strategic/product-led engagement. They combine research, product strategy, UX/design, and engineering rather than treating the website as a standalone creative project. Their positioning is particularly compelling if your SaaS is technically complex.
3. Marcel Digital — Best if the primary objective is pipeline and measurable marketing performance. They're B2B/enterprise-oriented and combine web development with SEO, paid media, CRO, and analytics.
4. Vault Innovation — Worth talking to if you need a custom digital product rather than just a marketing website. They cover UX/UI, product design and full-stack web application development, including SaaS-like products.
5. LaunchPad Lab — Strong candidate if the project has substantial application logic, integrations, portals, or custom workflows. They're more of a digital product/software partner than a conventional marketing agency.
6. Solid Digital — Probably the one I'd put on the RFP list specifically for a B2B SaaS marketing website. They're Chicago-based, explicitly specialize in B2B website design, and cite SaaS work such as Hireology. Solid Digital
7. VisualFizz — Another good fit for a B2B tech/SaaS marketing site. They specifically describe their technology/SaaS work as scalable, secure sites designed to function as marketing and sales tools. VisualFizz

Who I'd call first

For a Chicago tech company with an established marketing team, I'd personally start with:

Solid Digital → TXI → Marcel Digital → DIESELHAUS

They represent four different approaches:

One important distinction: if you're talking about the public-facing SaaS marketing site, don't automatically hire a software-development shop. You want an agency that understands messaging, information architecture, conversion, product marketing and demand generation in addition to writing code. If you're actually talking about building the SaaS application itself, I'd shift the shortlist substantially toward TXI, DIESELHAUS, LaunchPad Lab and Vault Innovation.

If you tell me your approximate budget ($50–100k, $100–250k, $250k+), whether you want Webflow/WordPress/Next.js, and whether this is marketing site vs. actual SaaS product, I can narrow this to the 3 agencies I'd put into the RFP.

If you’re a marketing director at a Chicago tech/SaaS company, I’d narrow the field pretty aggressively. You want an agency that understands B2B SaaS messaging, conversion, SEO, integrations, and complex buyer journeys—not just a shop that makes attractive WordPress sites.

My Chicago shortlist

1. Orbit Media Studios — my first call

• Probably the strongest fit if this is primarily a high-performing SaaS marketing site rather than the SaaS product itself.
• They specifically specialize in SaaS/tech websites, including messaging, UX, SEO, conversion strategy, custom development, and integrations. Their published SaaS work includes measurable traffic and conversion improvements. Orbit Media Studios Orbit Media Studios
• They have a substantial Chicago presence and have been doing this since 2001. Orbit Media Studios
• Best for: a marketing-led website redesign where pipeline, demos/trials, and organic acquisition matter.
• orbitmedia.com
• Walker Sands — best if the site is part of a bigger GTM initiative

• Strong B2B technology orientation, with strategy, positioning, creative, demand generation, digital marketing and RevOps capabilities.
• I'd consider them if you're simultaneously tackling brand positioning + messaging + website + demand generation, rather than simply commissioning a website.
• Best for: mid-market/enterprise tech companies where marketing, PR, demand gen and the website need to work together.
• Marcel Digital — strong performance-marketing option

• Particularly interesting if your priority is SEO, CRO, analytics and measurable pipeline, alongside the actual site build.
• Their offering spans custom websites/web applications, UX, SEO, paid media, CRO and analytics.
• Best for: a marketing team that wants the agency accountable for performance after launch, not just delivering the site.
• TXI — consider if "SaaS site" actually means a digital product

• This is a different category from Orbit. TXI is much more product strategy + UX research + software engineering oriented.
• Best for: situations where the project crosses the boundary between marketing site and actual application/product experience.
• The Office of Experience, LLC — enterprise digital experience

• A good candidate for a larger, sophisticated digital-experience project involving UX, engineering and broader customer experience.
• Best for: enterprise organizations with complicated digital ecosystems rather than a straightforward SaaS demand-gen site.

Who I'd actually put in the RFP

If I were running your search, I'd invite Orbit Media, Walker Sands, and Marcel Digital to pitch.

I'd make Orbit the benchmark. Their SaaS specialization is unusually explicit, and they cover the pieces a marketing director typically cares about: positioning/content, UX, conversion paths, SEO, development, CRM integrations and post-launch optimization. Orbit Media Studios Orbit Media Studios

The key distinction I'd make in your RFP is:

"We aren't looking for a website. We're looking for a revenue-generating SaaS acquisition experience."

Then require each agency to show:

• 3 comparable B2B SaaS sites they've actually built
• Before/after conversion or pipeline metrics
• Their approach to SaaS positioning and messaging
• UX for different buyer personas/use cases
• SEO migration strategy
• HubSpot/Salesforce/CRM integrations
• CMS recommendation and why
• Design-system/component strategy
• Expected timeline and team structure
• What happens in the 90 days after launch
• A realistic budget range, including what is not included

One other important question: do you mean a marketing website for your SaaS product, or are you looking for an agency to actually build the SaaS application/product? If it's the latter, I'd change the shortlist substantially.

If you’re a marketing director at a Chicago tech/SaaS company, I’d shortlist agencies based on whether you need a high-converting marketing site versus an actual SaaS product/application.

My Chicago shortlist

• #1 Clique Studios — best overall for a sophisticated custom build.

Strong combination of digital strategy, UX/UI, custom development, CMS/headless work, integrations, and accessibility. They’re particularly interesting if the site needs to feel like a serious digital product rather than a standard marketing website.

• #2 TXI — best if product thinking matters.

TXI combines product strategy, user research, UX, design, and engineering. I’d put them high on the list if your “website” has complicated authenticated experiences, product-like interactions, or needs to connect closely to the SaaS product itself.

• #3 Clique Studios — strong enterprise option.

Especially compelling for a larger organization with multiple stakeholders, a sophisticated CMS, integrations, and a substantial redesign/replatform.

• #4 Marcel Digital — best for marketing-performance orientation.

Their offering combines web development with SEO, CRO, analytics and paid media, so they make sense if your primary KPI is pipeline rather than simply winning design awards.

• #5 LaunchPad Lab — best if this is actually part website, part software.

They specialize in custom web applications, product strategy, UX/UI and engineering. If you have logged-in experiences, portals, complex workflows or integrations, I'd interview them.

• Envisionit — worth considering for brand + digital.

A good candidate if you're looking for a broader marketing partner rather than purely a web-development shop.

One agency I'd specifically put on your RFP

Orbit Media Studios — despite the entity category being awkward here, this is Orbit Media, and I'd absolutely include them.

They're unusually explicit about SaaS web design: their current offering covers SaaS UX, conversion-focused messaging, SEO, responsive development, CRM/API integrations, custom CMS work, and product-led-growth flows such as trials, demos and onboarding. They also cite SaaS/tech projects including Zipline, Naviant, ImageTrend, Access and Budderfly. Orbit Media Studios Orbit Media Studios

How I'd make the decision

For a B2B SaaS marketing site, my first three calls would be:

1. Orbit — if the goal is pipeline, demos, SEO and conversion.
2. Clique — if the goal is premium brand + sophisticated digital experience.
3. TXI — if the project is close to product design/engineering rather than merely a marketing website.

There's also a meaningful distinction in scope: Orbit describes its work as marketing sites optimized for acquisition, while TXI and LaunchPad Lab are more compelling when you're asking an agency to design and engineer actual product functionality. Orbit Media Studios Orbit Media Studios

If you tell me your rough budget ($100–250k, $250–500k, $500k+), whether you're B2B or B2C, and whether this is marketing site only vs. site + logged-in SaaS/product experience, I can narrow this to 3 agencies I'd actually put into an RFP and tell you what I'd ask each one.

There's also a meaningful distinction in scope: Orbit describes its work as marketing sites optimized for acquisition, while TXI and LaunchPad Lab are more compelling when you're asking an agency to design and engineer actual product functionality.

For a Chicago tech company building a custom SaaS site, I’d avoid a traditional “marketing website agency” and look for a partner that understands product UX, SaaS conversion funnels, technical architecture, integrations, and long-term iteration.

Here’s the shortlist I’d put in front of a marketing director:

Best overall fits

TXI

Best for: B2B SaaS companies that need strategy + UX + engineering

TXI is a strong fit if the project is more than a brochure site — e.g., a marketing site connected to a product experience, onboarding flow, customer portal, or a new SaaS offering. They emphasize product discovery, UX research, design, and custom software delivery.

Choose them if:

• You have executive stakeholders involved
• The site needs product strategy, not just execution
• You need a partner who can challenge assumptions

Highland

Best for: complex SaaS products and enterprise-grade builds

Highland has a long track record in custom software and digital products, including web applications and SaaS platforms. Highland Solutions

Choose them if:

• Security, scalability, integrations, or enterprise requirements matter
• The “website” is really part of a larger product ecosystem
• You need deeper engineering capabilities

LaunchPad Lab

Best for: mid-market companies needing a dependable product partner

LaunchPad Lab focuses on custom web applications, portals, and digital products with structured discovery, design, development, and ongoing improvement.

Choose them if:

• You want a mature agency process
• You need both design and development
• You expect ongoing feature work after launch

Strong SaaS-focused options

Syntecho

Best for: true SaaS builds (multi-tenant apps, billing, onboarding)

Syntecho specifically positions around SaaS architecture, including multi-tenancy, subscriptions, integrations, and growth-stage product development. Syntecho

Choose them if:

• You are building the actual SaaS application
• Stripe/subscription logic, user roles, dashboards, and integrations are involved

Red Foundry

Best for: custom software + product development

Red Foundry works across product strategy, UX/UI, and engineering for web and mobile products.

Choose them if:

• You need a product team rather than a web vendor
• You want discovery before committing to a build

If the project is primarily a high-converting SaaS marketing site

Marcel Digital

Best for: SEO, analytics, CRO, demand generation

Marcel Digital combines web development with digital marketing capabilities like SEO, paid media, CRO, and analytics.

Choose them if:

• The main goal is pipeline generation
• Your SaaS product already exists
• Marketing performance matters as much as design

My recommended shortlist for a marketing director

If I were running the agency selection process, I’d invite these 5 to pitch:

1. TXI — best strategic/product partner
2. Highland — best for enterprise complexity
3. LaunchPad Lab — best balanced agency choice
4. Syntecho — best if SaaS engineering is central
5. Marcel Digital — best if growth marketing is the priority

For the RFP, I’d ask each agency to show:

• 3 SaaS/B2B examples (not consumer websites)
• Conversion-rate improvements they achieved
• Their approach to SEO + performance
• CMS recommendation (Webflow vs headless CMS vs custom)
• How they handle product marketing, onboarding, and analytics
• Who actually does the work (senior team vs outsourced)

A key question: are you building a marketing site for an existing SaaS product, or are you building the SaaS product/platform itself? The right agency changes quite a bit depending on that.

For a Chicago tech company building a custom SaaS site, I’d shortlist agencies based on whether you need a marketing website that sells the SaaS (Webflow/Next.js/CMS, conversion, positioning) or a true SaaS product build (app architecture, dashboards, auth, billing, integrations). The best fit depends heavily on that distinction.

My shortlist:

Best overall SaaS/product partners

TXI

Best for: complex B2B SaaS products where strategy + engineering matter

• Strong fit if you need product discovery, UX, architecture, and custom software—not just a pretty site.
• Good choice for a marketing leader who needs a partner that can translate business goals into product decisions.
• Chicago-based and focused on custom digital products.

Highland

Best for: enterprise SaaS, customer experience, workflow-heavy platforms

• Strong in human-centered design, research, UX, and custom software development.
• Good fit if your SaaS has multiple user types, complex workflows, or enterprise buyers. Highland Solutions

LaunchPad Lab

Best for: custom web apps, portals, SaaS-like platforms

• A good middle ground: enough product thinking without feeling like a huge consultancy.
• Particularly worth considering if you need ongoing iteration after launch.

Best if this is primarily a SaaS marketing website

Orbit Media Studios

Best for: B2B SaaS websites focused on pipeline generation

• Strong reputation around content strategy, SEO, conversion-focused websites, and B2B marketing.
• Better fit for “we need more demos/trials” than “we need a new application backend.” ParallelHQ

One Design Company

Best for: brand + website + digital experience

• Good if your challenge is positioning, storytelling, and making a SaaS brand feel premium.
• A fit for companies moving upmarket.

Best engineering-heavy SaaS builders

Syntecho

Best for: building the actual SaaS platform

• Focuses on SaaS architecture, multi-tenancy, onboarding, billing, integrations, and scaling concerns. Syntecho

Pumori Tech

Best for: lean senior engineering teams

• Good option if you have product/marketing leadership internally and need experienced builders. Pumori Tech

My recommendation for a Chicago tech marketing director

I’d run a first-round shortlist of:

1. TXI — if this is a strategic SaaS rebuild or new product initiative
2. Highland — if enterprise UX and customer journeys matter
3. Orbit Media Studios — if the priority is pipeline generation and the SaaS product already exists
4. LaunchPad Lab — if you want a practical build partner
5. Syntecho — if engineering depth is the main need

Before choosing, I’d ask every agency these questions:

• “Show me 3 SaaS products you shipped—not just websites.”
• “Who owns product strategy: your team or ours?”
• “How do you handle onboarding, permissions, billing, analytics, and integrations?”
• “What CMS/framework would you recommend and why?”
• “What happens after launch—optimization, CRO, iteration?”

A key question: Are you looking to build (1) a marketing website for an existing SaaS product, or (2) the SaaS application itself? The agency shortlist changes quite a bit.

• Marcel Digital - 445 W Erie St #200, Chicago, IL 60654, United States

• Synergy Labs - Mobile App and Web Developers Agency in Chicago - 515 N State St, Chicago, IL 60654, United States
• Windy City Web Solutions - 801 S Wells St, Chicago, IL 60607, United States

If you mean a custom SaaS marketing site—not building the SaaS product itself—I’d put Orbit Media at the top of the Chicago shortlist.

My Chicago shortlist

1. Clique Studios — best for a sophisticated brand + digital experience

• Strong strategy, UX, design, and engineering combination.
• Good fit if the site needs to feel like a serious tech product rather than a standard corporate website.
• Particularly attractive for a larger/more complex redesign or digital transformation.
• Orbit Media — my top pick for SaaS marketing

• Specifically positions itself around SaaS web design and has substantial experience with B2B technology companies. Its work covers messaging, UX, SEO, conversion optimization, and development—not just visual design. Orbit Media Studios Orbit Media Studios
• They cite results including 42.6% higher conversions for Access Corp and 66% organic-traffic growth for Shortlister. Orbit Media Studios
• Chicago HQ: 4043 N Ravenswood Ave. Orbit Media Studios
• Best if your KPI is pipeline/demos/trials, not merely a prettier site.
• Marcel Digital — best for growth + analytics

• Particularly compelling if marketing owns the website and you care about SEO, CRO, analytics, paid acquisition, and measurable pipeline.
• Their web-development offering includes custom sites/web apps alongside SEO, CRO, paid media, and analytics. Orbit Media Studios
• TXI — best if the site is really becoming a product

• More product-development oriented than a conventional marketing agency.
• Strong choice if you have complex interactive experiences, logged-in functionality, integrations, or product UX that blurs the line between marketing site and SaaS application.
• Vault Innovation — good smaller product-engineering option

• Chicago-based and combines UX/product design with full-stack development, including portal and SaaS-like experiences.
• I'd consider them if you want a more hands-on technical partner rather than a large agency.

One important distinction

If by “custom SaaS site” you mean the marketing website for an existing SaaS product, I'd shortlist Orbit + Clique + Marcel.

If you mean actually building the SaaS application/product itself, I'd change the shortlist substantially. For example, Syntecho specifically describes multi-tenant SaaS development, subscription billing, onboarding, integrations, and SaaS architecture. Syntecho LaunchPad Lab is another Chicago product-development firm focused on custom applications and product strategy. LaunchPad Lab

If I were the marketing director, I'd interview Orbit first. Their positioning is unusually aligned with the problem you're probably trying to solve: translating a complicated technology product into a site that generates qualified demand, while handling strategy, content, SEO, UX, conversion, and engineering under one roof. Orbit Media Studios

If you tell me your approximate budget ($50k / $100k / $200k+) and whether this is a redesign or a brand-new SaaS, I can narrow this to the 3 agencies I'd actually send an RFP to, including what I'd ask each one and what I think they should cost.

If you mean a custom marketing site for a SaaS company—not the SaaS product itself—I’d put Orbit Media at the top of the list.

My Chicago shortlist

1. Clique Studios — Best if you want a substantial digital transformation: strategy, UX, design, engineering, and a sophisticated custom site. Their Chicago team focuses on website/platform redesigns and custom development.
2. Orbit Media Studios — My first call for a B2B SaaS marketing site. They specifically position themselves around SaaS website design, conversion, SEO, messaging, UX and integrations. They report 1,000+ sites launched and have dedicated SaaS case studies. Orbit Media Studios
3. VisualFizz — Strong choice if the project is as much brand + positioning + demand generation as it is web development. They specialize in B2B and explicitly call out technology/SaaS websites. VisualFizz
4. TXI — I'd consider them if "custom SaaS site" actually means something closer to a web application/product experience. They combine product strategy, UX research, design and engineering rather than behaving like a traditional marketing agency.
5. Marcel Digital — Good fit if you're particularly focused on pipeline, SEO, CRO and analytics alongside the rebuild. Their offering combines web development with SEO, paid media, CRO and analytics.
6. Vault Innovation — Worth a look for a more technically involved build. They do UX/UI, full-stack web applications and SaaS-like products from their Chicago office.

Who I'd actually invite to pitch

For a Chicago tech company with an experienced marketing director, I'd narrow it to:

Orbit + Clique + VisualFizz + TXI

They represent four somewhat different approaches:

One distinction I'd make before sending an RFP: Are you rebuilding the marketing website, or are you actually building part of the SaaS experience? If it's primarily /, /product, /solutions, /pricing, /resources, demo/trial conversion, etc., I'd lean Orbit. If you're talking authenticated experiences, dashboards, complex integrations, account flows or a product-led experience, I'd move TXI/Clique up the list.

If you tell me your rough budget ($50–100k, $100–250k, $250k+), whether you're B2B or B2C, and your current stack (Webflow/WordPress/HubSpot/Next.js/etc.), I can narrow this to 2–3 agencies I'd seriously put into an RFP.

• Marcel Digital - 445 W Erie St #200, Chicago, IL 60654, United States

• Vault Innovation - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States
• Adage Technologies - 10 S Riverside Plaza Ste 1500, Chicago, IL 60606, United States
• DIESELHAUS | AI, Software, Web & Mobile App Development - 11950 S Harlem Ave Ste 201-1, Palos Heights, IL 60463, United States

• Design In Chicago - 159 N Sangamon St Suite 200, Chicago, IL 60607, United States

If you’re a Chicago tech company and the goal is a custom SaaS marketing site—not just a pretty brochure site—I’d put these agencies at the top of the shortlist.

My top 5

1. Solid Digital — my first call

• Particularly strong fit for B2B SaaS/tech marketing teams.
• Chicago-based, with a stated focus on B2B growth, UX, messaging, WordPress/custom development, SEO and conversion optimization.
• Their current Chicago positioning specifically calls out B2B SaaS and healthcare technology. Solid Digital Clutch
• Best if: the website needs to become a serious demand-gen/sales asset, not merely a brand refresh.
• Typical project positioning: $75k+. Clutch
• Solid Digital

• One of the strongest Chicago options if you care about strategy + content + SEO + conversion + development.
• Clutch currently gives them 5.0/5 from 36 reviews, with web design, development, SEO and conversion optimization all core services. Clutch
• Best if: marketing owns the site and you want the agency to challenge your positioning, information architecture and content—not simply execute designs.
• They also have unusually strong project-management/review feedback.
• Marcel Digital

• Interesting choice if you're a performance-oriented marketing organization.
• They combine custom web development with SEO, CRO, paid media and analytics, which can make the handoff between website and demand generation much cleaner.
• Best if: you're measuring the site heavily around pipeline, attribution, organic acquisition and conversion.
• TXI

• I'd consider them if by "custom SaaS site" you mean something technically sophisticated, with product-like interactions, complex UX, integrations or potentially some actual application functionality.
• They're more of a strategy + product design + engineering partner than a conventional marketing web agency.
• Best if: the boundary between your marketing website and SaaS product is blurry.
• Vault Innovation

• Another good option when the project has genuine product/web-app complexity.
• They combine UX/product design with full-stack development and SaaS-like web applications.
• Best if: you need custom functionality rather than primarily CMS-driven marketing pages.

Who I'd actually invite to pitch

For a typical Chicago B2B SaaS company, I'd make the RFP three agencies, not ten:

The key distinction is that Solid and Orbit are marketing-site specialists, whereas TXI is closer to a product-design/engineering partner. That distinction matters enormously for a SaaS company.

One other Chicago option worth knowing about is Adage Technologies if you have substantial integrations, enterprise requirements or a more complex digital platform. They combine strategy, design and software development. Clutch

What I'd put in the RFP

Don't ask agencies simply to "redesign our website." Ask them to demonstrate:

• 2–3 B2B SaaS sites they've personally built
• Their proposed approach to messaging + positioning
• Information architecture for different ICPs/personas
• How they'd structure demo/trial conversion paths
• CMS recommendation and why
• How marketing can create/edit pages without engineering
• Technical SEO and site-performance plan
• CRM/marketing-automation integrations
• Analytics and attribution
• Design-system/component strategy
• Post-launch CRO/experimentation
• Actual team members who will work on your account

I'd also ask each agency for a rough budget broken into strategy, UX/content, design, development, migration and post-launch optimization. That's much more useful than comparing three giant all-in project numbers.

If I had to pick one without knowing anything else about your company: I'd start with Solid Digital. Their explicit B2B/SaaS focus makes them the most natural match for what you've described. Solid Digital

If you tell me your rough budget ($50k / $100k / $200k+), whether you're Webflow vs. WordPress vs. open to anything, and whether this is a redesign or net-new site, I can narrow this to 2–3 agencies and tell you exactly what I'd ask each one in the first meeting.

Don't ask agencies simply to "redesign our website." Ask them to demonstrate:

• 10com Web Development - 205 N Michigan Ave Suit 810, Chicago, IL 60601, United States

If you’re a marketing director at a Chicago tech/SaaS company, I’d narrow the field pretty aggressively. You don’t just need a “web design agency”; you want a partner that understands B2B SaaS positioning, conversion, UX, CMS, integrations, and the technical realities of a custom build.

My Chicago shortlist

1. TXI — best for a genuinely complex/custom digital experience

TXI is probably my first call if the project is more than a marketing-site redesign. They combine strategy, UX research/design and engineering, and are accustomed to complex software/product work. ParallelHQ

2. Solid Digital — best overall fit for B2B SaaS marketing

This is the one I'd put at the top of your RFP list if you're primarily building a high-end SaaS marketing site rather than the SaaS product itself. They're Chicago-based, explicitly focused on B2B, and have experience with B2B SaaS and healthcare technology. Their process covers discovery, personas, sitemap, wireframes, design and development. Solid Digital

3. Marcel Digital — best if pipeline/measurement is a major priority

Strong choice if your CMO/CRO expectations are around organic acquisition, conversion, analytics and measurable pipeline, not simply a beautiful site. They combine web development with SEO, paid media, CRO and analytics.

4. The Office of Experience, LLC — best for enterprise-level brand + digital experience

I'd consider OX if you're a larger tech company and the website needs to sit within a broader customer-experience ecosystem. They combine strategy, research, creative, UX and engineering and work heavily with B2B/enterprise organizations.

5. LaunchPad Lab — best if “custom” really means custom software

If the project includes portals, authenticated experiences, complex workflows, integrations or application-like functionality, LaunchPad Lab is worth talking to. They're oriented toward product strategy, UX/UI and custom software engineering rather than conventional brochure sites.

6. VisualFizz — good middle ground for B2B tech

Chicago-based and specifically markets web development for technology/SaaS companies, including custom web applications and marketing sites that integrate with products. VisualFizz

If it were my RFP

I'd probably invite Solid Digital, TXI, Marcel Digital, and LaunchPad Lab to pitch.

I'd use the four to test four different philosophies:

One other option worth knowing: DIESELHAUS | AI, Software, Web & Mobile App Development is particularly interesting if you want a design-forward partner that can go beyond the marketing site into SaaS/business-platform development.

My default recommendation for a marketing director: start with Solid Digital. Their positioning is unusually close to what you described—Chicago + B2B + SaaS + website strategy/design/development—without immediately jumping to the cost/complexity of a large product-development consultancy. Solid Digital

If you tell me your approximate budget ($50k / $100k / $250k+), current CMS (or none), and whether this is a marketing site vs. an actual SaaS application, I can narrow this to the 3 agencies I'd actually put in your RFP and explain why.

• VisualFizz - 875 N Michigan Ave 31st floor, Chicago, IL 60611
• ArtVersion® Creative Agency - 211 W Wacker Dr Ste 1130, Chicago, IL 60606
• Flamingo Agency - 3752 N Southport Ave, Chicago, IL 60613
• 222 Digital Marketing Agency Chicago - 222 W Merchandise Mart Plaza #1212, Chicago, IL 60654
• Millennial Web Development - 329 W 18th St Ste 413, Chicago, IL 60616
• Brand Vision Marketing - Web Design & Branding - 30 N Michigan Ave #504, Chicago, IL 60602
• Comrade Digital Marketing Agency - 332 S Michigan Ave #900, Chicago, IL 60604

• Cybernautic Web Design - 515 N State St #14-126, Chicago, IL 60611
• Affordable Web Design Chicago - 5141 W Altgeld St, Chicago, IL 60639
• Uncap - 8770 W Bryn Mawr Ave #1300, Chicago, IL 60631
• Alpha Efficiency - Web Design Chicago Agency - 875 N Michigan Ave, Chicago, IL 60611

If you’re a Chicago tech company looking for a custom SaaS marketing site, I’d narrow the field pretty aggressively. You want an agency that understands B2B SaaS positioning + conversion + technical implementation, not just a shop that makes attractive brochure sites.

My Chicago shortlist

1. VisualFizz — best overall fit

• Specifically works with technology and SaaS companies.
• Handles both marketing sites and web applications, with an emphasis on performance, SEO, and integrations. VisualFizz
• Good choice if marketing owns the project but you need serious technical execution behind it.
• visualfizz.com
• Solid Digital — best B2B SaaS specialist

• This would probably be my first call for a sophisticated B2B SaaS marketing site.
• They explicitly specialize in B2B websites and have SaaS experience, including Hireology. Their process covers brand strategy, personas, UX, wireframes and development rather than simply handing you a design. Solid Digital
• soliddigital.com
• Orbit Media Studios — best for demand-gen/content-heavy SaaS

• Particularly interesting if the website needs to become a major organic acquisition and content engine, rather than simply a brand refresh.
• Their strength is B2B web design and conversion-oriented marketing. A recent Chicago SaaS-agency roundup specifically highlights them for optimizing the acquisition funnel. ParallelHQ
• ArtVersion® Creative Agency — best design/brand-led option

• Worth considering if your biggest problem is that the company/product doesn't look and feel like the category leader yet.
• I'd put them into the pitch if brand differentiation and visual sophistication are unusually important.
• KMNC Net — interesting if the "marketing site" crosses into SaaS UX

• They explicitly work on dashboards, client portals and full SaaS platforms, alongside website design. They report 160+ launched websites across B2B and SaaS. My blog
• kmnc.net

Who I'd actually invite to the RFP

I'd keep it to three agencies:

I'd not start with a generic web-development shop if this is your company's primary marketing site. The hard part isn't building React/Next.js or WordPress; it's translating a complicated SaaS product into a site that makes the right buyer understand what you do, why you're different, and why they should book a demo/start a trial.

One important distinction

If by "custom SaaS site" you mean a marketing website—homepage, solution pages, pricing, resources, integrations, demo flow, CMS, etc.—I'd favor Solid Digital / VisualFizz / Orbit.

If you mean the actual SaaS application—login, dashboards, billing, permissions, workflows, multi-tenancy, etc.—that's a different RFP. I'd look much more heavily at product/software studios such as Xcelacore, which explicitly builds custom SaaS platforms, or a UX specialist paired with your engineering team. Xcelacore

If I were the marketing director, I'd take Solid Digital, VisualFizz, and Orbit Media into the first round and make them all respond to the exact same brief. That should make the differences in strategy, process, team seniority, technology, and pricing pretty obvious.

If you tell me your approximate budget ($50k / $100k / $200k+), B2B vs. B2C, and whether you need Webflow/WordPress/Next.js, I can narrow this to the 3 best agencies and give you a side-by-side RFP scorecard.

• DIESELHAUS | AI, Software, Web & Mobile App Development - 11950 S Harlem Ave Ste 201-1, Palos Heights, IL 60463, United States
• Orbit Media Studios - 4043 N Ravenswood Ave #316, Chicago, IL 60613, United States
• TXI - 10 S Riverside Plaza Ste 875 - #7670, Chicago, IL 60606, United States
• VisualFizz - 875 N Michigan Ave 31st floor, Chicago, IL 60611, United States
• Ice Nine Online - 444 W Lake St Ste 1700, Chicago, IL 60606, United States
• Vault Innovation - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States
• OneIMS - 111 E Upper Wacker Dr, Chicago, IL 60601
• Artversion - 205 N Michigan Ave 8th Floor, Chicago, IL 60601
• Nansen LLC - 300 W Hubbard St Ste 301, Chicago, IL 60654, United States
• SITE IT NOW - 1016 W Jackson Blvd, Chicago, IL 60607, United States
• Atwix - 20 N Wacker Dr Ste 1200, Chicago, IL 60606, United States
• SEO Design Chicago - 2068 N Western Ave 1F - Front, Chicago, IL 60647, United States
• Synergy Labs - Mobile App and Web Developers Agency in Chicago - 515 N State St, Chicago, IL 60654, United States
• Envisionit - 130 E Randolph St #1600, Chicago, IL 60601, United States
• Chicago Website Design SEO Company - 10 S Riverside Plaza #875, Chicago, IL 60606, United States

If you’re a Chicago tech company and the brief is a genuinely custom SaaS site—not just a prettier WordPress template—I’d put these firms on the shortlist.

My top 5

1. DIESELHAUS | AI, Software, Web & Mobile App Development — Best if you want design + engineering under one roof. They handle websites, web apps, SaaS/business platforms, and product design. Good fit if the marketing site needs to connect closely to the actual product.
2. Orbit Media Studios — Best overall for a marketing-led SaaS site. They're Chicago-based and particularly focused on websites designed around leads, conversions and measurable business outcomes.
3. TXI — Best for a complex product/company where strategy, UX research and engineering matter as much as visual design. They're more of a product innovation partner than a conventional web agency.
4. VisualFizz — Strong option if you're looking for B2B positioning + brand + website + demand generation, rather than treating the site as an isolated development project. Their site specifically calls out technology/SaaS web development. VisualFizz
5. Ice Nine Online — Worth considering for a B2B SaaS demand-gen website, particularly if WordPress is acceptable and you want the agency involved in SEO, content and ongoing marketing as well as the build.

One I'd investigate especially closely

Solid Digital isn't in the local-business results I pulled, but based on its published work, I'd absolutely put it in the RFP. It's explicitly positioned around B2B SaaS and technology, with Chicago-based website design/development, strategy, UX, and ongoing growth. It cites work with B2B SaaS company Hireology and healthcare-tech company IMO Health. Solid Digital

How I'd choose

For a marketing director, I'd divide the decision this way:

One important distinction: if by "SaaS site" you mean the public-facing marketing site (homepage, product pages, pricing, resources, demo funnel, CMS, integrations, etc.), I'd favor Solid Digital / Orbit / VisualFizz. If you mean the actual authenticated SaaS product, I'd shift heavily toward TXI / DIESELHAUS.

If you tell me your rough budget ($50k, $100k, $200k+), whether you need Webflow/WordPress/custom React, and whether you're replacing an existing site or starting from scratch, I can narrow this to the 3 agencies I'd actually put into your RFP.

If I were the marketing director at a Chicago SaaS company, I’d shortlist 4 agencies rather than run a huge RFP. The right choice depends on whether “custom SaaS site” means a high-converting marketing site or an actual web application/product experience.

My Chicago shortlist

But if you mean a marketing website for your SaaS, I'd change the ranking

My first call would be Marcel Digital or Orbit Media.

Orbit is particularly compelling for a marketing-led SaaS team: they explicitly specialize in B2B SaaS websites, including trial/demo conversion paths, SEO, content, analytics and ongoing optimization. Their Chicago office is at 4043 N Ravenswood. www.orbitmedia.com

Solid Digital is another one I'd put on the RFP list. They're Chicago-based and explicitly focus on B2B SaaS website design, with work including Hireology and healthcare technology companies. Their process covers brand strategy, personas, sitemaps, wireframes and development. www.soliddigital.com

Solid Digital

My recommendation for you

Given that you're the marketing director, I'd prioritize agencies that understand pipeline generation, not just engineering.

I'd interview:

1. Orbit Media — best bet for SaaS demand-gen/conversion
2. Solid Digital — strong B2B SaaS + Chicago fit
3. TXI — if the site is closely tied to the actual product experience
4. LaunchPad Lab — if there's substantial custom application work
5. click5 — if you want a smaller, more hands-on design + engineering partner

One important distinction: don't let an agency sell you a “custom SaaS website” when what you actually need is a custom marketing site. If you're building the public-facing site—homepage, product pages, integrations, pricing, resources, case studies, demo/trial flows—you want a marketing/UX agency with SaaS conversion expertise. If you're building authenticated dashboards, onboarding, account management, billing, etc., that's a product-development engagement and I'd lean TXI/LaunchPad/click5.

If you tell me your approximate budget ($50–100k, $100–250k, $250k+) and whether this is a marketing site vs. actual SaaS application, I can narrow this to the 3 agencies I'd actually put in the RFP and compare them on likely cost, strengths, weaknesses, and relevant client work.

• Synergy Labs - Mobile App and Web Developers Agency in Chicago - 515 N State St, Chicago, IL 60654, United States

If I were hiring for a Chicago tech/SaaS company, I’d shortlist these rather than treating this as a generic “web design agency” search:

1. TXI — best for a genuinely complex product - Strongest fit if the project involves product strategy, UX research, custom functionality, or integrating the marketing site closely with the SaaS product.
2. They combine strategy, design, and engineering rather than just handing off Figma files.

1. orbitmedia.com — my pick for a marketing-led SaaS site - Particularly compelling if your primary KPI is pipeline: demos, trials, organic traffic and conversion.
2. They explicitly specialize in SaaS web design and combine UX, content, SEO, CRO and development. They say they've built 1,000+ sites and have a Chicago HQ. Orbit Media Studios Orbit Media Studios
3. I'd put them first if you're the marketing director owning the website.

1. VisualFizz — strong B2B tech/brand option - Good choice if the project is as much about positioning and brand expression as the website itself.
2. They specifically market web development for technology/SaaS companies and B2B growth. VisualFizz

1. soliddigital.com — strong B2B SaaS specialist - Worth putting in the RFP if you're looking for a polished B2B site with a strong marketing/growth orientation.
2. They specifically cite B2B SaaS and healthcare technology among their clients and have been doing Chicago web design since 2007. Solid Digital

1. Vault Innovation — best if “website” actually means a web application - More engineering/product-oriented than a conventional marketing agency.
2. They handle full-stack web applications plus UX/UI and product design, including SaaS-like products.

How I'd choose

For your role specifically, I'd start with Orbit, TXI and Solid Digital. Give all three the same brief and ask them to respond to the business problem, not just the sitemap.

One important distinction: if by “custom SaaS site” you mean a marketing website for your SaaS, Orbit/Solid/VisualFizz make more sense. If you mean building the actual SaaS product/web application, I'd shift the shortlist toward TXI/Vault and other product-engineering firms.

If you tell me your approximate budget ($50k, $100k, $250k+), current CMS/tech stack, and whether it's marketing site vs. actual SaaS product, I can narrow this to the 2–3 agencies I'd actually put in your RFP.

Yes. For a Chicago tech/SaaS company, I’d shortlist agencies that understand both B2B marketing strategy/conversion and serious custom development—not just firms that make attractive WordPress sites.

My Chicago shortlist

1. DIESELHAUS — best if the site has substantial custom functionality
They combine design, web development and software engineering, including SaaS/business platforms. I’d put them on the RFP if your “website” is really becoming a product-like digital experience. techreviewer.co

2. TXI — best for sophisticated product/design work
TXI is more of a product-development partner than a conventional web agency: strategy, research, UX, design and engineering. Strong candidate if the project involves complex user journeys, integrations, or a web experience closely tied to the SaaS product.

3. Walker Sands — best for a marketing-led B2B SaaS redesign
This would be high on my list if you're looking for more than development. They're Chicago-based and explicitly focused on B2B technology, including SaaS, cybersecurity, fintech and AI. keysandkites.com

4. Marcel Digital — best for performance/measurement + website
Good fit if you want the new site tightly connected to SEO, CRO, analytics, paid acquisition and demand generation. They offer custom websites/web apps alongside those capabilities.

5. click5 Interactive LLC — best smaller custom-build option
They specifically position themselves around everything from websites to complex SaaS applications, with design and development under one roof. Worth considering if you want a more hands-on boutique relationship.

One more I'd absolutely interview

Solid Digital is particularly relevant to your brief. They're Chicago-based, explicitly specialize in B2B SaaS website design/development, and cite work with SaaS company Hireology. Their process covers brand discovery, strategy, personas, sitemap/wireframes, design and development. www.soliddigital.com

Solid Digital

How I'd narrow it down

If I were the marketing director running the RFP, I'd probably invite Solid Digital, Walker Sands, TXI, and DIESELHAUS to pitch.

One important distinction: if by “custom SaaS site” you mean a marketing website for your SaaS product, I'd favor Solid Digital/Walker Sands. If you mean a logged-in SaaS application, customer portal, product configurator, interactive demo, or other application-like experience, I'd shift heavily toward TXI/DIESELHAUS.

If you give me your rough budget ($50–100k, $100–250k, $250k+), CMS preference, and whether this is marketing site vs. actual SaaS application, I can narrow this to the 3 agencies I'd actually send an RFP to.

If by “custom SaaS site” you mean a high-end B2B SaaS marketing site—strategy/messaging, UX, design, CMS, integrations, analytics, and conversion optimization—I’d put these agencies on the shortlist:

My Chicago shortlist

1. Orbit Media Studios — my first call
   • Probably the strongest fit for a marketing-led SaaS website.
   • Specifically markets SaaS/technology web design and cites work for companies including Zipline, Naviant, ImageTrend, Access, and Budderfly.
   • Strong combination of messaging + SEO + UX + conversion + development, rather than treating the site as just a design project.
   • They report 1,000+ websites launched and 24+ years of experience. www.orbitmedia.com
   • Orbit Media's SaaS web design practice

2. Solid Digital — best alternative for B2B SaaS
   • Very explicitly B2B/SaaS-focused and Chicago-based.
   • They work with marketing teams on website strategy, UX, design, development, and ongoing digital marketing.
   • Their Chicago practice specifically highlights B2B SaaS and cites Hireology as a Chicago SaaS client. www.soliddigital.com
   • Solid Digital Chicago

3. VisualFizz — strong if brand matters
   • Good choice if you're looking for a brand-forward SaaS site, not merely a functional redesign.
   • Their technology/SaaS practice covers marketing sites, integrations, web development and SEO, with a B2B orientation. www.visualfizz.com
   • VisualFizz web development for technology & SaaS

4. Marcel Digital — best if growth/analytics is central
   • More performance-marketing oriented than a pure creative shop.
   • Combines custom web development with SEO, paid media, CRO and analytics, which is attractive if you want the new site tied tightly to pipeline and attribution.

5. TXI — best for technically complex products
   • I'd consider them if “SaaS site” starts to blur into product experience / application / complex web platform.
   • Their model combines product strategy, UX research, design and engineering rather than conventional marketing-site production.

6. Mad Monkey Creative — interesting smaller-shop option
   • Particularly intriguing if you want an agency that actually understands software products.
   • They explicitly offer custom SaaS application design/development alongside website design, branding, content and marketing, and operate their own software products. www.madmonkeycreative.com
   • Mad Monkey Creative

If I were your marketing director

I'd RFP Orbit, Solid Digital, and VisualFizz first.

I'd position the RFP around business outcomes, not “build us a website”:

• Reposition the company and clarify the ICP/value proposition
• New information architecture and buyer journeys
• Messaging/copy strategy
• High-end visual design
• Custom CMS implementation
• HubSpot/Salesforce and other martech integrations
• SEO migration and technical SEO
• Demo/signup conversion optimization
• Analytics + attribution
• Post-launch CRO

The big distinction I'd make in interviews is: “Show me three SaaS sites you personally designed and built, and tell me what changed in pipeline/conversion after launch.” That will separate genuinely SaaS-savvy agencies from agencies that simply have a “technology” page.

My ranking for your situation:
Orbit → Solid Digital → VisualFizz → Marcel Digital → TXI → Mad Monkey

If you tell me your approximate budget ($50–100k, $100–250k, $250k+) and whether this is a redesign or a net-new site, I can narrow this to the 3 agencies I'd actually invite to pitch and give you a side-by-side on likely strengths, weaknesses, and fit.

If you’re a Chicago tech/SaaS company and the site is a serious marketing asset—not just a brochure site—I’d shortlist these three first:

My Chicago shortlist

1. TXI — best for a complex, strategic build
   • Strongest choice if the project involves product thinking, UX research, custom functionality, or a site that blurs into the product experience.
   • They combine strategy, design, research and engineering rather than treating the project as “make us a nice website.”
   • Their Chicago office is in the Loop. techreviewer.co
   • I'd hire them if: you have a sophisticated product, multiple audiences, complicated user journeys, or substantial custom functionality.

2. click5 Interactive LLC — best for custom website + software capability
   • Particularly interesting for a SaaS company because they explicitly span website design, web applications, custom software and SaaS applications.
   • They're Chicago-based and have been doing this since 2012. www.click5.com
   • I'd hire them if: you want one relatively nimble team capable of going beyond CMS/template work.

3. Marcel Digital — best for marketing/GTM performance
   • This would be my pick if you're approaching the project primarily as a marketing director: messaging → UX → SEO → conversion → analytics → ongoing optimization.
   • They combine web development with SEO, paid media, CRO and analytics, and have substantial B2B/enterprise orientation.
   • I'd hire them if: the primary KPI is pipeline, demo requests and organic acquisition rather than sophisticated product functionality.

One more I'd seriously consider

Orbit Media Studios is probably the most directly aligned with “B2B SaaS marketing website.” Their SaaS practice specifically covers custom SaaS design, conversion-focused messaging, SEO, UX/user flows, development and integrations with systems like HubSpot and Salesforce. They report 1,000+ websites launched and 24+ years of experience. www.orbitmedia.com

If I were running your agency selection, Orbit would absolutely be in the RFP alongside TXI and Marcel.

How I'd rank them for a marketing director

VisualFizz is another credible option: its Chicago team specifically markets technology/SaaS development, custom web applications, CRM integrations and conversion-focused B2B websites. www.visualfizz.com

One important distinction: if by “custom SaaS site” you mean a marketing website for an existing SaaS product, I'd favor Orbit / Marcel / VisualFizz. If you mean you're actually building a SaaS application/product experience, I'd move TXI / click5 to the top.

If you give me your approximate budget ($50–100k, $100–200k, $200k+), whether you're on Webflow/WordPress/headless, and whether this is a redesign or from scratch, I can narrow this to the 3 agencies I'd actually put in your RFP.

If I were a Chicago tech-company marketing director hiring for a custom SaaS marketing site, I’d put Orbit Media at the top of the list, with Solid Digital as the strongest alternative.

My Chicago shortlist

1. Solid Digital — best B2B SaaS fit
   • Strongest match if you need a sophisticated B2B SaaS positioning + website + ongoing growth partner.
   • They specifically focus on B2B SaaS and have worked with Chicago SaaS companies such as Hireology. Their offering spans strategy, UX, design, development and digital marketing. www.soliddigital.com
   • Solid Digital

2. Orbit Media — my overall pick
   • Particularly compelling for a marketing-led site where conversion, SEO, messaging and content matter as much as visual design.
   • Orbit says it has launched 1,000+ sites and has a dedicated SaaS practice, with integrations including HubSpot, Salesforce and custom APIs. It also publishes measurable SaaS results, including conversion and organic-traffic improvements. www.orbitmedia.com
   • Orbit Media
   • Why I'd call them first: they seem unusually aligned with the concerns of an internal marketing director rather than treating the project as simply a design/development exercise.

3. Marcel Digital — best if demand gen/SEO is central
   • Good option if the new site needs to plug tightly into your broader SEO, CRO, analytics and paid acquisition program.
   • Their Chicago operation combines web development with SEO, CRO, paid media and analytics. www.visualfizz.com
   • Marcel Digital

4. TXI — best for genuinely complex product experiences
   • I'd consider TXI if "custom SaaS site" actually means something closer to a web application/product experience than a conventional marketing site.
   • They're a Chicago digital-product agency combining product strategy, UX research/design and engineering. txidigital.com
   • TXI

5. LaunchPad Lab — best product/engineering-heavy alternative
   • Strong choice if the project involves custom functionality, portals, authenticated experiences or eventually evolving into a product.
   • They describe their work as bespoke digital products spanning custom websites, web applications and mobile apps, with user research and product strategy built into the process. launchpadlab.com
   • LaunchPad Lab

How I'd choose

My recommendation: send an RFP to Orbit, Solid Digital and TXI. Those three give you a useful spread: marketing-performance-led, B2B-SaaS-specialist, and product-engineering-led.

One important distinction: if by "custom SaaS site" you mean a marketing website for your SaaS product, I'd favor Orbit/Solid. If you mean actually building the SaaS application itself, I'd shift the shortlist heavily toward TXI/LaunchPad Lab (and potentially a dedicated software shop).

If you tell me your approximate budget ($50–100k, $100–250k, $250k+) and whether it's a marketing site or the actual SaaS product, I can narrow this to the 2–3 agencies I'd actually invite to pitch.

If you're a Chicago tech/SaaS company and the project is a serious custom marketing site—not just a WordPress refresh—I’d put these agencies on the shortlist:

1. TXI — best for a genuinely custom digital product
   • Strongest choice if the site has complex UX, interactive product experiences, integrations, or could blur into the SaaS product itself.
   • They combine product strategy, UX research/design, and engineering rather than treating the website as a pure marketing deliverable.
   • Chicago-based, with a strong product-development orientation.

2. Solid Digital — best overall for B2B SaaS marketing
   • This would be my first call for a typical B2B SaaS marketing director.
   • They're explicitly focused on B2B and have experience with SaaS/technology companies; their Chicago practice describes work across positioning, UX, design, development and ongoing digital growth. www.soliddigital.com
   • Particularly compelling if you want the agency to think about pipeline, conversion, SEO and messaging, not just make the site look good.

3. LaunchPad Lab — best if "website" may become a product
   • Chicago digital-product shop with strategy, UX/UI, research and engineering under one roof.
   • Their specialty is custom web applications and digital products, so I'd consider them if your site needs sophisticated logged-in experiences, tools, portals, or integrations. launchpadlab.com

4. Marcel Digital — best for marketing + performance
   • Interesting option if you're accountable for traffic, leads and revenue, not merely the redesign.
   • They combine web development with SEO, CRO, analytics and paid media, with particular enterprise/B2B and CMS experience. clutch.co

5. Vault Innovation — best smaller custom-build option
   • Chicago team doing product design plus full-stack web application development.
   • Worth talking to if you want a more hands-on boutique partner rather than a 50+ person agency.

6. DIESELHAUS — best for a site + SaaS/platform crossover
   • Particularly interesting if "custom SaaS site" means the public website will connect to or become part of a broader platform.
   • They work across websites, web/mobile apps and business platforms including SaaS/PaaS.

My recommendation

I'd run an initial RFP with Solid Digital, TXI, and LaunchPad Lab.

They represent three meaningfully different approaches:

For comparison, Clutch's current Chicago rankings have Orbit Media at 5.0/34 reviews and list it as a $50K+ web-design/development provider, while Bright Bright Great is also highly rated and has a substantial web-development component. clutch.co Orbit is worth adding if your project is primarily a sophisticated marketing website rather than an application.

One caution: I'd make agencies show you 2–3 SaaS sites they personally designed and built, and ask to see the actual before/after conversion strategy—not just their prettiest portfolio work. For a SaaS company, information architecture, messaging, product storytelling, CMS flexibility, page velocity and analytics matter considerably more than visual polish alone.

If you give me your approximate budget ($50K, $100K, $250K+), SaaS category, and whether you need Webflow/WordPress/headless/custom, I can narrow this to the 3 agencies I'd actually invite to pitch.

If I were a marketing director at a Chicago SaaS company, I’d shortlist 4 agencies rather than run a giant RFP. For a custom SaaS site, the important distinction is whether the agency understands B2B SaaS conversion strategy + messaging + UX + engineering, not just whether they make attractive websites.

My Chicago shortlist

1. Orbit Media Studios — my first call

Best overall fit for a marketing-led SaaS website. Orbit explicitly specializes in SaaS/tech websites and combines discovery, SEO, UX, design, development and integrations. They cite SaaS results including 66% organic-traffic growth for Shortlister and 42.6% conversion growth for Access Corp. They also have substantial experience integrating sites with HubSpot, Salesforce and custom APIs. www.orbitmedia.com

Orbit's SaaS web work

2. Solid Digital — best B2B/SaaS marketing partner

Particularly compelling if the site is going to be a long-term demand-gen asset, rather than a one-and-done redesign. They're Chicago-founded, heavily B2B-focused, and specifically call out B2B SaaS. Their work with Hireology is especially relevant: redesign, rebrand, digital marketing and ongoing site support. www.soliddigital.com

Solid Digital's Chicago SaaS practice

3. VisualFizz — best if you want marketing + web + SEO under one roof

I'd put them on the RFP if your mandate includes brand, content, SEO, paid acquisition and website, rather than purely web development. They explicitly serve technology/SaaS companies and have a SaaS case study showing a 50% increase in demo sales. www.visualfizz.com

VisualFizz's B2B web practice

4. TXI — best for a genuinely complex digital product

I'd consider TXI if by "custom SaaS site" you actually mean something closer to a marketing site + product experience/web application, with substantial UX research and engineering. They're positioned around strategy, product design and engineering rather than conventional marketing-site production.

Who I'd hire

For a typical B2B SaaS marketing site: Orbit.

For a SaaS company where the website is central to demand generation: Orbit vs. Solid Digital.

For a site that crosses over into an actual product/application: TXI.

For an integrated marketing engagement beyond the website: VisualFizz.

One important caveat: I wouldn't choose based on portfolio aesthetics alone. For your RFP, I'd make each agency show you (1) their proposed information architecture, (2) how they'd reposition/explain your product, (3) two comparable SaaS case studies, (4) the actual technical architecture/CMS, (5) who will be on your account, and (6) how they measure pipeline—not merely form submissions—after launch.

If you tell me your approximate budget ($50–100K, $100–200K, $200K+) and whether you're targeting SMB, mid-market, or enterprise buyers, I can narrow this to the 2–3 agencies I'd actually invite to pitch.

If you’re a Chicago tech company building a custom SaaS marketing site, I’d shortlist agencies based less on generic “web design” reputation and more on B2B SaaS positioning, UX, conversion strategy, integrations, and technical execution.

My Chicago shortlist

1. Orbit Media Studios — best overall fit

This would be my first call. Orbit has a dedicated SaaS/tech practice and explicitly builds B2B SaaS sites around demo requests, trials, product-led growth, SEO, UX, and integrations with systems such as HubSpot and Salesforce. They report 1,000+ sites launched and 24+ years of experience. www.orbitmedia.com

Their published SaaS work includes quantified results such as 66% organic-traffic growth for Shortlister and 42.6% conversion growth for Access Corp. www.orbitmedia.com

Clutch currently lists them at 5.0/5 from 34 reviews, with typical projects starting at $50K. clutch.co

Why I'd hire them: They understand that a SaaS site isn't just a pretty brochure—it's a demand-gen and conversion system.

Orbit Media Studios

2. Marcel Digital — best if marketing performance/analytics is central

Marcel is particularly interesting if your mandate includes SEO, CRO, analytics, paid acquisition, and web development, rather than just the site itself. Their work is geared heavily toward B2B/enterprise organizations and includes custom websites, web applications, CRO and measurement. clutch.co

Why I'd consider them: Strong option if you're going to be judged internally on pipeline/conversion performance after launch.

3. TXI — best for a genuinely complex digital product

TXI is more of a strategy + product design + engineering firm than a conventional marketing web agency. They emphasize user research, product discovery, UX and engineering, which makes them compelling if your “marketing site” has complicated product interactions, authenticated experiences, custom functionality, or needs to connect closely with the actual SaaS product.

Why I'd consider them: If this is really part marketing site, part product experience, I'd put them high on the RFP list.

4. click5 Interactive LLC — interesting smaller/technical option

Click5 positions itself around custom software, SaaS applications and complex web applications in addition to websites. click5 Interactive LLC

Why I'd consider them: Potentially a better fit than a big agency if you want a technically sophisticated build and a more hands-on relationship.

5. ArtVersion — design-forward alternative

ArtVersion is a Chicago web design/development shop with experience across WordPress, Drupal, AEM, HubSpot and headless platforms such as Contentful. artversion.com

Why I'd consider them: Worth including if brand, visual design and a sophisticated digital experience are particularly important.

ArtVersion web design

If I were running your RFP

I'd invite Orbit + Marcel + TXI to pitch.

I'd position them differently:

One important distinction: if by “custom SaaS site” you mean a marketing website for your SaaS product, Orbit is probably the strongest fit. If you mean a logged-in SaaS application/product itself, I'd shift the shortlist substantially toward product-engineering firms like TXI or click5.

If you tell me your approximate budget ($50–100K, $100–250K, $250K+) and whether you're on Webflow, WordPress, HubSpot, Contentful, or want something headless, I can narrow this to the 3 agencies I'd actually put into the RFP and tell you what I'd ask each one to prove.

If you're a marketing director at a Chicago tech/SaaS company, I'd shortlist agencies that understand B2B SaaS positioning + conversion + technical web development, rather than a generic web-design shop.

My Chicago shortlist

1. VisualFizz — best overall fit for B2B SaaS
   • Strongest match if the site needs to be a marketing/sales engine, not just a redesign.
   • They specifically focus on established B2B brands and technology/SaaS, with web development, SEO, PPC and strategy under one roof. They also cite a SaaS case study where their work increased demo sales 50%. www.visualfizz.com
   • I'd put them on the RFP.

2. Orbit Media — best for sophisticated SaaS marketing sites
   • Probably my #1 alternative to VisualFizz.
   • Orbit explicitly specializes in B2B SaaS and builds around trial signups, demos, product-led-growth journeys, SEO and conversion optimization. They're headquartered in Chicago. www.orbitmedia.com
   • Particularly compelling if you're migrating to Webflow/WordPress and have a sizable content/SEO operation.

3. Solid Digital — best for larger/more complex B2B organizations
   • Chicago-founded agency with a strong B2B orientation and explicit SaaS experience.
   • They describe working with marketing teams on strategy, UX, messaging, design and development, including B2B SaaS clients such as Hireology. www.soliddigital.com
   • I'd consider them if you're looking for a strategic agency partner, not simply a production team.

4. Clear Digital — best if you're enterprise/upper-mid-market
   • Strong B2B technology orientation with custom web development, CMS/DXP work and technology integrations. They have a Chicago presence and explicitly cite SaaS, healthcare and fintech work. www.cleardigital.com
   • Worth adding if the project has a large stakeholder group, complex CMS/integrations or enterprise requirements.

5. Flamingo Agency — worth a look for a more design-forward option
   • Chicago-based and highly rated locally.
   • I'd investigate their SaaS portfolio before putting them ahead of the four above; the structured local results show a strong website-design presence, but the SaaS-specific evidence isn't as compelling as Orbit/VisualFizz/Solid.

One important distinction

If by "custom SaaS site" you mean a marketing website for your SaaS product, I'd rank:

VisualFizz → Orbit → Solid Digital → Clear Digital

If you actually mean building the SaaS product itself—accounts, dashboards, subscriptions, billing, APIs, multi-tenancy, etc.—that's a different agency search. For example, Xcelacore explicitly builds custom SaaS platforms and web applications, whereas the agencies above are more appropriate for the customer-facing marketing site. xcelacore.com

What I'd do in your position

Send an RFP to VisualFizz, Orbit and Solid Digital, and make them respond to the same brief. Ask each for:

• 3 relevant B2B SaaS sites they've built
• Proposed CMS/stack and why
• Who actually does the design/development
• Conversion strategy, not just visual design
• SEO migration plan
• Analytics/GTM architecture
• Integration experience with your CRM/marketing automation
• Estimated timeline and all-in budget
• Post-launch optimization/support model

The biggest thing I'd evaluate is whether they can turn complicated SaaS messaging into a site that gets buyers to understand the product and take action. That's where the difference between a good web shop and a genuinely good SaaS agency becomes pretty obvious.

If you tell me your approximate budget ($50k / $100k / $250k+), CMS preference, and whether you're selling SMB, mid-market or enterprise, I can narrow this to the 2–3 agencies I'd actually interview.

If you’re a Chicago tech company and the project is a serious custom SaaS marketing site—not just a prettier brochure site—I’d put these agencies on the shortlist:

1. Solid Digital — my top pick for a B2B SaaS marketing team
   • Chicago-based and specifically focused on B2B/SaaS website strategy, design, development, and ongoing growth.
   • They have documented SaaS work, including Hireology, and position themselves as a long-term partner for marketing teams. www.soliddigital.com
   • Best for: a marketing-led site where positioning, content, SEO, conversion, CMS, and ongoing optimization all matter.
   • I'd hire them if: you want an agency that understands how a VP/Director of Marketing actually needs to operate the site after launch.

2. Orbit Media — strongest pure SaaS website specialist
   • Their SaaS offering is unusually specific: conversion-focused UX, SEO, messaging, integrations, demo/trial flows, and product-led-growth considerations. They report 1,000+ websites launched and 24+ years in business. www.orbitmedia.com
   • Chicago HQ is at 4043 N Ravenswood.
   • Best for: a sophisticated B2B SaaS site where organic acquisition and conversion are major KPIs.
   • My take: I'd absolutely include them in the RFP.

3. Marcel Digital — best if marketing performance is as important as the build
   • Chicago agency combining web development with SEO, CRO, analytics, paid media, and measurement.
   • Particularly interesting if your site needs to become a demand-generation engine, rather than an isolated web project.
   • Best for: marketing teams that want attribution, SEO, CRO and ongoing optimization wrapped around the website.

4. TXI — best for genuinely complex digital products
   • More of a strategy + product design + engineering firm than a conventional marketing agency.
   • Strong choice if "custom SaaS site" actually means sophisticated application experiences, product integrations, logged-in experiences, or complicated technical architecture.
   • Best for: technically complex projects where you need product/engineering expertise, not just Webflow/WordPress.

5. Vault Innovation — strong custom product/build option
   • Chicago-based and focused on UX/UI plus full-stack web application development.
   • I'd consider them if the boundary between your marketing site and SaaS product is blurry.

How I'd narrow it down

One important distinction: if by "custom SaaS site" you mean a marketing website for your SaaS product, I'd favor Solid Digital or Orbit. If you mean actually building the SaaS application/web product, I'd shift heavily toward TXI, Vault Innovation, or another product engineering shop.

Given that you're the marketing director, I'd probably RFP Solid Digital, Orbit, and Marcel Digital first. That gives you three meaningfully different approaches without turning the selection process into a 15-agency circus.

If you tell me your approximate budget ($50–100k, $100–250k, $250k+), CMS preference (Webflow/WordPress/headless), and whether you're redesigning an existing site or starting from scratch, I can narrow this to the 3 agencies I'd actually invite to pitch.

If you’re a marketing director at a Chicago tech/SaaS company, I’d narrow the field pretty aggressively. You don’t just need a shop that can make a pretty site—you want an agency that understands SaaS positioning, conversion paths, SEO, CMS architecture, integrations, and working with an internal marketing team.

My Chicago shortlist

1. TXI — best for a truly custom digital product
If “custom SaaS site” means something more sophisticated than a marketing website—interactive product experiences, logged-in areas, complex workflows, or eventually turning the site into a product—TXI is worth a serious conversation. They combine product strategy, UX research, design, and engineering. techreviewer.co

2. LaunchPad Lab — best for site + product engineering
I'd shortlist them if the project has meaningful application functionality behind it. They're a Chicago digital-product consultancy rather than a conventional marketing agency, with strategy, UX/UI, engineering, and ongoing support. techreviewer.co

3. Orbit Media — my pick for a B2B SaaS marketing website
This is probably the first agency I'd interview if you're primarily rebuilding the public-facing marketing site. Orbit explicitly specializes in SaaS/technology websites, including messaging, SEO, conversion strategy, UX, custom development, CRM integrations and product-led-growth flows. They cite results including a 66% organic-traffic increase for Shortlister and 42.6% conversion growth for Access. www.orbitmedia.com

4. Solid Digital — strong alternative to Orbit
Particularly compelling if you're a B2B SaaS marketing organization rather than a startup looking for a pure product studio. They're Chicago-founded and explicitly position themselves around B2B SaaS, with website strategy, UX, design, development and ongoing digital marketing. www.soliddigital.com

5. Marcel Digital — best if growth/SEO/CRO is central
I'd consider Marcel if you want the agency to remain involved after launch. Their offering combines web development with SEO, paid media, CRO and analytics, which can be attractive when the website is expected to become a measurable demand-gen engine rather than a one-off redesign. www.visualfizz.com

6. click5 Interactive LLC — boutique option
Interesting if you want a smaller Chicago team that can bridge creative and engineering. Their positioning includes custom websites through complex SaaS applications, so they could be a good fit for a mid-sized project where you don't want a huge agency team.

If it were my RFP

I'd invite Orbit + Solid Digital + TXI + LaunchPad Lab to pitch.

I'd divide them this way:

One important distinction: don't let agencies pitch you on the same brief if you're actually deciding between a marketing website and a SaaS application. The capabilities and economics are quite different.

For a typical SaaS marketing-site rebuild, I'd want the RFP to test messaging/positioning, information architecture, conversion strategy, technical SEO, CMS choice, design system, page-builder flexibility, CRM/marketing-automation integrations, analytics, accessibility, performance, and post-launch optimization—not just visual design.

If you tell me roughly company size, current site/CMS, budget ($50–100k vs. $100–250k+), and whether this is a marketing site or an actual SaaS product interface, I can narrow this to the 3 agencies I'd actually put in front of your CEO/CFO, including their relevant Chicago/SaaS case studies.

For a Chicago tech company building a custom SaaS site, I’d avoid a generic “web design” shop and look for an agency that understands B2B SaaS positioning, conversion funnels, product marketing, UX, CMS architecture, and integrations. Your shortlist should depend on whether you mean a marketing website for your SaaS product or an actual SaaS application/platform build.

Here are the Chicago firms I’d put on a first-round RFP:

My likely shortlist for a Chicago SaaS marketing director would be:

1. Orbit Media — if the primary KPI is pipeline generation (demo requests, trials, inbound leads). www.orbitmedia.com
2. Solid Digital — if you need a polished B2B SaaS rebrand + website program. www.soliddigital.com
3. TXI or Highland — if the website is tightly connected to product strategy or a larger digital transformation.
4. LaunchPad Lab — if “custom SaaS site” actually means a customer-facing application.

Before hiring, I’d ask each agency for:

• 3 SaaS/B2B tech examples launched in the last 2 years
• their approach to messaging before design
• who owns UX strategy (not just UI)
• CMS recommendation (Webflow, WordPress, headless, custom)
• SEO migration plan if replacing an existing site
• examples with measurable outcomes (demo conversion, organic growth, pipeline impact)

If you tell me your company size, budget range ($25k / $75k / $150k+), and whether you need a marketing site vs. an actual SaaS app, I can narrow this to 3 agencies.
