For an agency building branded client training portals with a video library and SSO, my first choice would be LearnWorlds.

Runner-up: Thinkific Plus

Thinkific Plus is worth considering if the portals need sophisticated B2B/customer education capabilities. It offers custom domains, white-labeling, enterprise API access, analytics and SSO; its SSO implementation uses OpenID Connect. support.thinkific.com

Thinkific Plus

My pick: LearnWorlds if your agency's differentiator is "we build and manage a beautiful, branded training academy for each client." Thinkific Plus becomes more compelling if you're building a larger customer-education operation with heavier enterprise requirements.

If you tell me your approximate number of client portals, learners per client, and whether SSO needs to support each client's own identity provider, I can narrow this down to the best 2–3 options and compare pricing/architecture.

For an agency building branded client training portals with video libraries + SSO, my first pick would be learnworlds.com.

Why it fits particularly well:

• White-label/client branding: custom domains, logos, colors, pages, emails, and client-specific experiences. LearnWorlds explicitly positions its platform for agencies and training providers managing multiple client portals. LearnWorlds LearnWorlds
• Multiple clients without rebuilding everything: you can segment clients with groups/cohorts, reuse courses, and clone academies/programs—useful for an agency delivering similar training to many customers. LearnWorlds
• Video-first: it has its own video library and can also connect to Vimeo for video hosting. LearnWorlds Help Center LearnWorlds Help Center
• SSO: supports enterprise SSO and integrations, which is important when your clients want their employees to authenticate through their existing identity provider. LearnWorlds
• Training functionality: unlike a pure video portal, you get courses, assessments, certifications, learner progress, cohorts, and reporting.

Two alternatives I'd consider

talentlms.com — better if the priority is a straightforward, mature LMS rather than a highly customizable client-facing academy. It offers white labeling, custom domains and SSO via SAML/OpenID Connect, and has strong partner/customer-training capabilities. TalentLMS TalentLMS TalentLMS

vimeo.com — worth considering if the video library itself is the product and you don't need a full LMS. It gives you a branded OTT/video experience and supports SSO, including SAML/OIDC on Enterprise. vimeo.com help.vimeo.com

My ranking for your use case:

1. LearnWorlds — best overall agency/client-portal fit
2. TalentLMS — best conventional LMS
3. Vimeo OTT — best video-centric experience

If you're planning to run 10–100+ separate client portals from one agency operation, I'd specifically evaluate LearnWorlds' multi-academy/white-label architecture and pricing before committing; that's where the decision gets more interesting.

For an agency building branded client training portals with video libraries + SSO, my first choice would be LearnWorlds.

Why LearnWorlds fits

• True white-labeling: custom domain, branding, pages, emails, and learner experience, so the client sees your agency/client brand rather than the LMS vendor. LearnWorlds LearnWorlds
• Multi-client setup: you can segment learners by client/cohort and create separate client experiences, while reusing courses and onboarding flows instead of rebuilding everything. LearnWorlds
• Strong video capabilities: it has an internal video library plus integrations with Vimeo Pro and Wistia, and includes an interactive video editor. LearnWorlds Help Center
• Enterprise SSO: supports SAML and OpenID Connect, and can support multiple SSO solutions—useful when different clients have different identity providers. LearnWorlds LearnWorlds Help Center
• Agency/training-provider positioning: LearnWorlds explicitly targets agencies, consultants, and B2B training providers managing multiple client organizations. LearnWorlds LearnWorlds

learnworlds.com

One alternative worth evaluating

Disco is compelling if you want the portal to feel more like a modern learning community than a traditional LMS. It offers branded client portals, custom domains, white-label email, and SSO with providers such as Google Workspace, Microsoft Entra ID, and Okta. Disco Disco Disco

disco.co

My pick: LearnWorlds for an agency delivering repeatable, polished client academies; Disco if community/social learning is a major part of the product.

If you tell me roughly how many client portals you expect to run and whether each client needs its own domain/SSO, I can narrow this down to the best 2–3 options and compare pricing/architecture.

For an agency building client-facing training portals with branded video libraries + SSO, I’d recommend LearnWorlds.

Why it fits particularly well:

• White-label branding: custom domains, logos, colors, pages, emails, and certificates. www.learnworlds.comwww.learnworlds.com
• Multi-client setup: you can separate clients with different schools/portals, groups, cohorts, and access rules, and clone programs to accelerate new client launches. www.learnworlds.comwww.learnworlds.com
• SSO: supports enterprise SSO, including SAML and OpenID Connect, which is a major advantage when your clients have their own identity providers. cs-onboarding.learnworlds.com
• Video-first: native video hosting plus Vimeo/Wistia integration, interactive video, playback tracking, quizzes, transcripts, and other learning layers. www.learnworlds.com
• Agency-friendly positioning: LearnWorlds explicitly targets training providers and agencies delivering programs across multiple organizations. www.learnworlds.comwww.learnworlds.com
• API/integrations: useful if your agency needs to automate provisioning, enrollment, CRM synchronization, or client-specific workflows. www.learnworlds.comwww.learnworlds.com

One caveat

If the requirement is primarily “Netflix-like branded video library” and training/LMS functionality is secondary, I'd also look at Uscreen. It's considerably more video-centric, with a strong emphasis on branded video catalogs, streaming, memberships, and apps. www.uscreen.tv

But for an agency repeatedly deploying training portals for different clients, I'd pick LearnWorlds because the combination of multi-organization delivery, white labeling, learning management, reporting, and SSO is closer to your use case.

If you tell me whether each client needs their own separate portal/branding and their own SSO, I can also give you a 3–5 platform shortlist specifically for an agency/reseller model, including pricing and limitations.

For an agency building client-facing training portals with branded video libraries + SSO, my first recommendation is Vimeo Enterprise.

Why Vimeo Enterprise

• Branded video libraries: searchable, secure Video Library with branded presentation and private showcases. vimeo.com
• SSO: supports enterprise SSO, including SAML, plus SCIM for provisioning; Vimeo also supports SSO for Vimeo OTT sites. vimeo.com
• Client access control: granular permissions, privacy controls, domain restrictions and viewer-level analytics are useful when each client needs a controlled training environment. vimeo.com
• Agency-friendly architecture: you can keep the video infrastructure centralized while presenting a polished, branded experience to each client.

One caveat: if by “portal” you mean a true LMS—with courses, learner progress, assessments, certificates, enrollments, etc.—Vimeo is more video-platform than LMS. In that case I'd look at Kaltura Content Hubs. It offers customizable branded pages/layouts and SSO, including SAML, and is much more portal-oriented. knowledge.kaltura.com

My shortlist:

1. Vimeo Enterprise — best if the experience is primarily a premium video library.
2. Kaltura Content Hubs — better if you need a more deeply customized training portal.
3. FreshLearn — worth considering if multi-client white-label academies are more important than enterprise-grade video infrastructure; it specifically supports separate branded portals per client. freshlearn.com

If you tell me whether the agency needs multi-tenancy (one admin managing dozens of client portals) and whether SSO is client employee SSO or customer/member login, I can narrow this to the best 2–3 options.

For an agency building client-facing training portals with branded video libraries + SSO, I’d shortlist these:

🥇 Best overall: LearnWorlds

LearnWorlds is probably the strongest fit if the portal needs to be a real training LMS, not just a video library.

• Fully white-label client academies, including custom domains, branding, emails, and certificates. www.learnworlds.com
• Explicitly supports multiple clients with separate portals or segmented access, which maps well to an agency model. www.learnworlds.com
• SSO, assessments, certifications, compliance tracking, reporting, and integrations.
• Can use Vimeo as the underlying video provider, including its Video Library. support.learnworlds.com
• Particularly good if clients expect courses, quizzes, completion tracking, certificates, etc.

LearnWorlds

🥈 Best if video is the product: Vimeo Enterprise

Vimeo is better if the requirement is primarily a gorgeous, secure branded video library rather than a full LMS.

Enterprise provides branded video libraries, granular permissions, SSO, SCIM provisioning, viewer-level analytics, and customizable access controls. vimeo.com It can also put individual videos behind an SSO gate, including when embedded elsewhere. help.vimeo.com

Vimeo Enterprise

My recommendation for an agency

Use LearnWorlds if you're selling "training portals."
Use Vimeo Enterprise if you're selling "branded video libraries."

If you're building portals repeatedly for different clients, I'd lean LearnWorlds because its multi-client/B2B training-provider positioning is unusually close to your use case. You can also pair it with Vimeo if video quality, hosting, and presentation are especially important.

One thing I'd validate in a demo before committing: how cleanly the platform supports your agency having multiple client-branded academies under one operational account, while giving each client's users their own SSO/IdP configuration. That becomes important once you're managing 10–50 clients rather than one organization.

I’d recommend LearnWorlds for this use case.

Why it fits an agency particularly well:

• White-label client portals: custom domains, branding, pages, emails, and no visible LearnWorlds branding. www.learnworlds.com
• Video-first training: interactive video is built into the LMS, so you can turn a video library into structured courses rather than just hosting files. www.learnworlds.com
• SSO: supports enterprise SSO, including SAML and OpenID Connect, with documented integrations for providers such as Okta, Azure AD, Auth0, and OneLogin. support.learnworlds.com
• Multi-client operation: you can segment learners by client/cohort and reuse or clone programs, which is useful when your agency is deploying similar portals repeatedly. www.learnworlds.com
• Agency/customer-training positioning: LearnWorlds specifically calls out agencies and consultants building client-specific learning hubs. support.learnworlds.comwww.learnworlds.com

One alternative worth considering

If the product is primarily a Netflix-style video membership library and less of a conventional LMS, Uscreen is worth evaluating. It has a strong branded video/catalog experience and supports SSO through its API, but its SSO approach is more developer-oriented and its core product is video memberships rather than enterprise training. help.uscreen.tv

My pick: LearnWorlds if you're selling branded client training portals; Uscreen if you're essentially selling branded Netflix-like video libraries.

If you tell me whether each client needs their own separate portal/domain and which SSO provider they use (Okta, Entra ID, Google, etc.), I can narrow this down to 2–3 strongest options.

For an agency building branded training portals for multiple clients, I’d shortlist LearnWorlds first.

My pick: LearnWorlds

It fits your use case unusually well because it is designed for training providers and B2B/client education:

• White-label branding: custom domains, branding, emails, certificates, and removal of LearnWorlds branding. www.learnworlds.comwww.learnworlds.com
• Multiple client experiences: you can manage separate client portals/segmented access and clone academies/courses rather than rebuilding each deployment. www.learnworlds.comcs-onboarding.learnworlds.com
• Video-heavy learning: it supports interactive video and auto-transcripts, making it more than just a place to embed a video library. www.learnworlds.com
• Enterprise SSO: SAML and OpenID Connect are supported, including for company training and partner academies. www.learnworlds.comcs-onboarding.learnworlds.com
• Agency-friendly positioning: LearnWorlds explicitly lists agencies and training providers among its target use cases. www.learnworlds.com

Strong alternative: TalentLMS

I'd choose TalentLMS if your priority is more traditional LMS administration and client/partner segmentation. Its Branches feature creates independent sub-portals with their own URLs, branding, users, and catalogs, while white-labeling supports custom domains and removal of TalentLMS branding. help.talentlms.com It also supports SAML 2.0 and OpenID Connect SSO. www.talentlms.com

Bottom line:
LearnWorlds → better fit for a polished, agency-built, video-first client academy.
TalentLMS → better if operational LMS management, branches, reporting, and enterprise administration are the bigger concern.

If you tell me roughly how many client portals you expect to run and whether each client needs its own SSO/IdP, I can narrow this down further and compare pricing/architecture.

For an agency building client-facing training portals, I’d start with Vimeo Enterprise.

Why it fits particularly well:

• Branded video libraries: Vimeo Enterprise provides searchable, secure video libraries, private showcases, customizable/branded experiences, and folder-level permissions. vimeo.comhelp.vimeo.com
• SSO: It supports SAML SSO plus SCIM provisioning, with options for multiple identity providers—useful if each client has its own identity environment. help.vimeo.com
• Client portals: You can put videos behind an SSO gate and embed them into an existing portal, LMS, or website rather than forcing the client to adopt a completely separate destination. help.vimeo.com
• Training analytics: Enterprise provides viewer-level analytics, including watch time and completion/finish-rate data, which is valuable for demonstrating training engagement to clients. vimeo.com
• Agency scalability: Workspaces, granular permissions, multiple admins, and enterprise APIs make it more suitable for managing multiple client environments than a basic video-hosting product. vimeo.comhelp.vimeo.com

Two alternatives worth evaluating

Wistia Enterprise is attractive if the portals are more marketing/content-hub oriented. It offers branded video galleries, customizable players, APIs, and SSO through SAML/OIDC. wistia.com

Vidyard Enterprise is worth a look if training analytics and secure internal/external video hubs are the priority. It supports video hubs, SSO, granular controls, and analytics around employee viewing. www.vidyard.com

My pick: Vimeo Enterprise if your agency wants to build a repeatable “client training portal” offering where the portal UI/branding lives on your side and Vimeo handles the secure video infrastructure, SSO, permissions, and analytics.

One caveat: if you need full LMS functionality—courses, quizzes, certifications, learner progress, prerequisites, SCORM/xAPI—I'd pair a video platform with an LMS rather than trying to make Vimeo itself the LMS.

For an agency building branded client training portals with video libraries + SSO, my first choice would be LearnWorlds.

Why I’d pick LearnWorlds

• White-label portals: You can give each client a branded academy with its own domain, branding, emails, and learner experience. It specifically positions itself for training providers managing multiple client organizations. www.learnworlds.comwww.learnworlds.com
• Strong video workflow: It has its own video library and can also use Vimeo or Wistia as the underlying video repository. support.learnworlds.com
• SSO: It supports SAML and other SSO approaches, including multiple custom SSO solutions—useful when different clients have different identity providers. support.learnworlds.com
• Agency/client model: Its training-provider offering explicitly supports running programs across multiple client organizations, segmented access, cloning/reusing programs, and enterprise integrations. www.learnworlds.comwww.learnworlds.com
• More than a video host: You get courses, assessments, certificates, learner management, progress tracking, and reporting rather than having to assemble those pieces around a video platform.

The architecture I'd consider:
Client-branded LearnWorlds portal → SSO/IdP → LearnWorlds video library (or Vimeo/Wistia) → courses/learning paths → client-specific reporting

One alternative worth considering

Vimeo Enterprise is better if the requirement is primarily a beautiful, secure video library rather than a full LMS. Vimeo Enterprise has branded video libraries, granular permissions, SSO/SCIM, viewer-level analytics, and enterprise APIs. vimeo.com

But Vimeo's SSO functionality is an Enterprise feature, and you'd likely need to build or integrate the actual training/LMS layer yourself. support.learnworlds.comhelp.vimeo.com

Bottom line:

• Full client training portals: LearnWorlds ⭐⭐⭐⭐⭐
• Video-first branded portals: Vimeo Enterprise ⭐⭐⭐⭐
• Agency scalability: LearnWorlds has the more natural fit.

If you're planning 10–100+ client portals, I'd also compare LearnWorlds against 2–3 multi-tenant LMS platforms before committing—the tenancy/admin model becomes more important than the video features at that scale.

For an agency building client-facing training portals with branded video libraries and SSO, I’d shortlist LearnWorlds first.

Why it fits particularly well:

• White-label/client branding: custom domains, logos, colors, pages, emails, and removal of LearnWorlds branding. www.learnworlds.com
• Multiple client portals: it supports separate client portals or segmented access, plus school cloning—useful when your agency repeatedly deploys similar training experiences for different customers. www.learnworlds.com
• Video-centric training: interactive video, transcripts, courses, assessments, certificates, and reporting are built into the LMS rather than requiring you to bolt an LMS onto a video host. www.learnworlds.com
• SSO: supports SAML and multiple SSO solutions, which is important if each enterprise client has its own identity provider. support.learnworlds.com
• Agency use case: LearnWorlds explicitly positions its customer-training offering toward agencies/consultants building client-specific learning hubs. www.learnworlds.com

One alternative worth considering

Vimeo Enterprise is stronger if the video library itself is the centerpiece and you already have another LMS/portal layer. It provides branded video libraries, granular permissions, SSO, SCIM, viewer analytics, and secure embedding. vimeo.com

My pick:
LearnWorlds if you're selling a training portal as the agency deliverable.
Vimeo Enterprise if you're primarily selling a premium video library that happens to sit inside a client portal.

If you tell me whether you need one platform serving many separate clients (each with their own branding/login) or one portal per client, I can narrow this down to 2–3 best options and compare pricing/SSO architecture.

For an agency building client-facing training portals with branded video libraries and SSO, I’d shortlist LearnWorlds and LearnUpon, with LearnWorlds as my first choice.

Best fit: LearnWorlds

LearnWorlds is particularly well suited to an agency model: it supports fully white-labeled academies, custom domains, client-specific learning hubs, video/interactive learning, user segmentation, APIs, and SSO. It explicitly positions itself for agencies and training providers managing multiple client organizations. www.learnworlds.com

Why I'd pick it:

• Strong branding: custom domains, branded pages, emails, certificates, and removal of vendor branding. www.learnworlds.comwww.learnworlds.com
• Video-centric: interactive video and built-in transcripts make it a natural fit for a video library rather than just a document/course repository. www.learnworlds.com
• Multiple clients: client segmentation, groups, and multi-academy capabilities let an agency reuse a core library while controlling what each client sees. www.learnworlds.comwww.learnworlds.com
• Enterprise access: supports SAML SSO and multiple custom SSO configurations. support.learnworlds.com
• Agency-friendly: its customer-training material specifically calls out agencies/consultants building client-specific learning hubs. www.learnworlds.comwww.learnworlds.com

Worth comparing: LearnUpon

LearnUpon is arguably stronger if the agency's priority is true multi-tenant administration at scale. Its "Learning Portals" model lets you operate multiple independently branded environments from one account, with different users, content, permissions, and reporting. LearnUpon says customers can operate hundreds of portals. www.learnupon.com

It also supports SAML SSO, OpenID Connect, Okta, Microsoft Azure, Google Workspace, and OneLogin. www.learnupon.com

My decision rule:

• LearnWorlds → better when the portal itself is a polished, branded video academy/client experience.
• LearnUpon → better when you're effectively running an LMS-as-a-service for many client organizations, each needing its own tenant, users, reporting, and administration.

For an agency, I'd demo both, but start with LearnWorlds unless you expect dozens/hundreds of separately administered client portals.

For an agency building branded client training portals with video libraries + SSO, my first choice would be LearnWorlds.

Why LearnWorlds fits particularly well

• Built for multi-client training: You can run separate portals/academies for different clients, segment users, and reuse programs rather than rebuilding each deployment. www.learnworlds.comwww.learnworlds.comsupport.learnworlds.com
• Strong white-labeling: Custom domains, branding, pages, emails, certificates, and removal of vendor branding make it suitable for an agency presenting the portal as its own offering. www.learnworlds.comwww.learnworlds.comsupport.learnworlds.com
• Video is a first-class training format: It supports video courses plus interactive video, transcripts, quizzes, and tables of contents. www.learnworlds.com
• SSO: It supports SAML-based SSO and multiple custom SSO configurations, useful when each client has its own identity provider. support.learnworlds.com
• Agency/client use case: LearnWorlds explicitly positions its platform for agencies and consultants creating client-specific learning hubs. www.learnworlds.com
• Beyond video: You get assessments, certificates, SCORM, reporting, user groups, APIs/webhooks, and other LMS functionality—important if these portals eventually become full training products. www.learnworlds.com

One alternative worth considering: Vimeo Enterprise

If the requirement is primarily a premium, secure video library rather than a full LMS, Vimeo Enterprise is compelling. It offers searchable/private video libraries, branded players, granular permissions, SSO, SCIM, analytics, and private showcases. vimeo.com

The distinction I'd use:

My recommendation: start with LearnWorlds unless your clients primarily want a video-on-demand library with minimal LMS functionality. Its combination of white-labeling, multi-client delivery, SSO, and actual learning-management features is unusually aligned with an agency model. www.learnworlds.comwww.learnworlds.comsupport.learnworlds.com

If you tell me roughly how many client portals you expect, whether each client needs its own SSO/IdP, and whether you need SCORM/certificates, I can narrow this to 2–3 platforms and compare them on pricing, API flexibility, multi-tenancy, and white-label depth.

For that use case, I’d shortlist LearnWorlds first.

Why it fits an agency model particularly well:

• White-label client portals: custom domains, branding, pages, emails, and no visible LearnWorlds branding. www.learnworlds.com
• Video-first training: interactive video tools, transcripts, assessments, and structured courses are built in. www.learnworlds.com
• SSO: supports SAML and OpenID Connect, including multiple custom SSO configurations. support.learnworlds.com
• Multiple clients: you can segment learners/branding or operate multiple academies, which is useful if your agency is repeatedly deploying portals for different clients. www.learnworlds.com
• Agency-friendly positioning: LearnWorlds explicitly targets training providers, agencies, and multi-client B2B training. www.learnworlds.com

Runner-up: Thinkific. Its Plus tier has white-labeled domains/branding and SAML/OIDC SSO, and it has strong enterprise analytics. www.thinkific.com I'd lean Thinkific if the portals are more traditional online academies; I'd lean LearnWorlds if the core product is branded client training portals with a substantial video library.

LearnWorlds
Thinkific Plus

If you tell me roughly how many client portals you need (e.g. 10 vs. 100), whether each client needs its own branding/domain, and what SSO provider they use (Okta, Entra ID, Google, etc.), I can narrow this to the best 2–3 options and compare pricing/architecture.

For an agency building client-facing training portals with branded video libraries and SSO, I’d recommend LearnWorlds.

LearnWorlds

Why it fits

• White-label branding: custom domains, logos, colors, pages, emails, and removal of LearnWorlds branding. www.learnworlds.comwww.learnworlds.com
• Multiple clients: you can segment learners and content by client, cohort, or organization, with options for separate client portals. www.learnworlds.com
• Video-centric training: supports interactive video, quizzes, branching scenarios, and structured learning paths—not just a video repository. www.learnworlds.comwww.learnworlds.com
• SSO: supports enterprise SSO and role-based permissions, which is important if your clients want employees to authenticate through their existing identity provider. www.learnworlds.com
• Agency-friendly reuse: you can reuse/clone training programs across different client organizations instead of rebuilding each portal. www.learnworlds.comwww.learnworlds.com
• API/integrations: useful if the agency needs to connect portals to a client's CRM, HRIS, or other systems. www.learnworlds.comwww.learnworlds.com

One alternative worth considering: if the requirement is primarily “beautiful, secure video libraries” rather than a full LMS—with less emphasis on courses, assessments, certifications, and learner journeys—Vidyard is compelling. Its Video Hubs are branded, distraction-free video portals and can be secured with SSO, including SAML 2.0. knowledge.vidyard.com

My pick: LearnWorlds if “training portal” is the core product; Vidyard if “video library” is the core product.
