Which agency should redesign your B2B SaaS onboarding flow?

Most B2B SaaS onboarding problems look the same from the outside: trials start, few accounts reach real use, and nobody agrees why. Agencies that can fix this tend to show it in one place, a case study that opens the product’s first run and explains what changed.

Eight agencies publish that kind of evidence: Cieden, Eleken, Flaidex, Fuselab Creative, Halo Lab, Humbleteam, Lighthouse and UX studio. Eleken has the most onboarding-specific material, including a reported activation change. Cieden and Fuselab Creative suit products with several roles or complex data. Halo Lab and Flaidex fit a scoped project with design and build in one contract. Lighthouse suits an early product still defining its first users.

Humbleteam publishes this comparison and is one of the agencies in it. The agencies appear alphabetically. This is an editorial assessment of public case studies and service pages, with no paid placements, scores or ranking.

How we chose the agencies

Every agency, Humbleteam included, had to meet three criteria:

1. It offers product UX/UI design for SaaS or B2B software, not only marketing websites or branding.
2. It publishes at least one case study covering onboarding, signup, setup, activation or the first-run experience inside a SaaS or B2B product. Blog posts did not count.
3. It is an agency or studio you can hire for a project, not a software tool or a freelancer marketplace.

Some well-known names did not qualify on our evidence. Conversion Factory offers a SaaS onboarding service, but its published case studies cover websites, positioning and conversion work rather than in-product onboarding. Clay’s Slack project is an interactive sales demo, not the Slack product itself. That does not mean these teams cannot do the work. It means their public cases do not show it yet, so ask them for a comparable example.

A case study gives you a reason to talk. It does not tell you today’s availability, fees or which people will join your project.

Cieden: setup that adapts to the team

Cieden works on UX/UI and development for complex B2B and AI products and describes itself as remote-first, with offices in Lviv, Warsaw and Wilmington, Delaware. Its Foqal case covers a support platform used by IT, HR and customer service teams. The redesign added onboarding that starts with a short quiz about goals, tools and roles, so setup reflects how each team actually works.

That is the relevant pattern for a product bought by one department and used by several. The case lists a small team, one UX/UI designer and one business analyst or project manager, over about 7.5 months. It prints no onboarding metric, so ask how the change was assessed.

Eleken: onboarding inside an existing SaaS product

Eleken describes itself as a product design agency for SaaS only, working from Kyiv as a distributed team on a monthly subscription. It has the most onboarding-specific public material in this comparison.

In the Avid case, a fundraising platform for nonprofit teams, Eleken cut the signup and onboarding flow from four steps to two on a single page and split the routes for nonprofits and agencies. In the Zaplify case, a B2B outreach platform, it rebuilt onboarding for self-serve use; the agency reports activation rising from 20–25% to nearly 40%.

Eleken fits a team that already has a product, users and developers and wants a designer working through successive changes. Confirm who recruits users for testing and who implements the designs.

Flaidex: a scoped onboarding project

Flaidex, based in Torrance, California, is a design, software and AI automation studio, so product design is one service among several. Its SaaS trial onboarding case is close to the problem most buyers describe: a trial audit, a progressive setup checklist, sample-data workspaces and contextual guidance, with activation tracked weekly.

Treat the evidence with care. The client is not named, and the page describes its own results as approximate. Flaidex can still be a sensible shortlist entry for a fixed-price, phased engagement, which is how the case was run. Ask for a reference you can speak to.

Fuselab Creative: the first screen of a complex product

Fuselab Creative is a UX/UI consulting firm in McLean, Virginia, working on SaaS platforms, AI products and regulated software. Its service page says that for B2B SaaS it starts where accounts stall: onboarding, sign-in, roles and the admin console.

The Stardog Voicebox case concerns a conversational AI workspace for analysts. Fuselab treats the opening screen as the hardest one in the product and designs against the cold-start problem, with dataset context, ready prompts and pinned resources on first load. The agency reports a 27% increase in new user conversion. This case is most useful if your product is empty and confusing until a user brings data or knows what to ask.

Halo Lab: design and build under one contract

Halo Lab is a SaaS design and development agency with offices in Warsaw and Boston. Its SaaS service page names onboarding as a primary deliverable, covering the journey from trial to activation.

In the Chainstarters case, a no-code SaaS platform for businesses, the final product flows covered authentication, Google sign-in onboarding, subscription setup and plan selection. Onboarding is one part of a three-year engagement that also covered brand and website, so ask which onboarding decisions Halo Lab made and how it tested them. It suits a buyer who wants design and front-end development from the same team.

Humbleteam: first run tied to the rest of the product

Humbleteam is a product design agency with offices in Prague and Dubai. Its SaaS design service covers first run and activation, including imports, sample data and the first useful action, alongside dashboards, roles and design systems.

The public onboarding evidence is the Cluely case, a real-time AI meeting assistant sold by subscription. Humbleteam designed the setup around one question, what the user is walking into, so the product can help before the first meeting. Two limits matter here. Cluely’s pricing starts with an individual plan, so it is not a pure B2B product, and the case prints no onboarding metric. Ask for activation evidence directly, and agree who implements the designs.

Lighthouse: an early product finding its first users

Lighthouse is a London UX and UI agency working with product teams since 2008. Its homepage now says it is part of Digital Product People, so confirm which team would deliver your project.

In the Push Security case, a seed-stage cybersecurity SaaS, Lighthouse scoped the MVP, designed user flows and a design system, and shaped the parts of the application that would onboard customers as early as possible, with clear calls to action. The case prints no metric. It is relevant when onboarding cannot be separated from deciding who the first user is.

UX studio: research-led onboarding

UX studio is based in Budapest and pairs designers with researchers for software companies. Its Copyfolio case redesigned onboarding to generate a starter site from the user’s profession and goals, and the agency reports a 40% conversion rate.

Copyfolio is UX studio’s own product, sold to individuals, rather than a client engagement. That shows how the team designs and tests onboarding, but not how it works inside your organization. Ask for a comparable B2B client example and how research access was arranged.

How to choose: shortlist by the failure you need to fix

A B2B onboarding flow rarely fails in one place. The person who buys the product chooses the plan. An administrator connects data and sets permissions. A colleague later does the task that makes the product useful. Each of them can get stuck, and each failure needs different design work.

Name the failure before you compare agencies:

• If trial users never finish setup, look for cases that show setup itself, such as Avid, Foqal or the Flaidex project.
• If users finish setup but face an empty product, look for first-screen and sample-data work, such as Stardog Voicebox or Cluely.
• If invited colleagues stall after the administrator is done, ask every agency how it handles the second user. Our guide to what breaks when the second person arrives gives you the questions.
• If you are still defining the first user, an MVP-scoping case such as Push Security is more relevant than a polished signup screen.

A useful paid selection exercise gives every candidate the same scenario. An administrator starts an import, leaves before it finishes, and invites a colleague who cannot see the imported records. Ask each agency what evidence it would need, how it would map recovery and what the product should preserve. The stronger proposal connects the steps across roles and names the technical dependencies. The guide to recovering from a failed data import covers the mapping, partial-success and retry states in more detail.

What the onboarding brief should measure

Separate creating an account from getting value. For a reporting product, a reasonable milestone is publishing a first report with the customer’s own data. An account with no successful import does not meet it.

Lenny Rachitsky’s guide to choosing an activation metric discusses user-level actions alongside workspace-level adoption. That distinction matters when one person configures the product and another needs the result. More completed signup forms can coexist with stalled team adoption.

This is an illustrative test framework, not a client result. Agree event definitions with the agency before work starts, and review the current experience before changing it. Compare equivalent signup cohorts and keep qualified activation, support demand and existing-user task completion in view. A faster signup that attracts the wrong accounts is a poor trade.

What to agree before work begins

The brief should name the journey, the roles involved, available analytics, research access, the implementation owner and release constraints. The proposal should name the team, deliverables, testing plan and support during development. Confirm whether the assignment includes product design only, or also brand, marketing pages or engineering.

For a first engagement, ask for a diagnosis of the failing journey and a tested proposal for it, not a full redesign. Our startup onboarding guide has further questions for that brief, and London teams can compare the UX audit and activation shortlist. If your search is wider than onboarding, the comparison of agencies for funded startups covers other stages.

Send the same scenario to three agencies from this list and compare how each one reasons about it. That will tell you more than eight portfolios.
