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.

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.
