UX/UI design for B2B SaaS: choosing an agency for growth
Compare B2B SaaS design partners by product scope, onboarding evidence, user roles, and the measures that show whether a first session became useful.
Startups and B2B SaaS
Published Updated 6 min read
A B2B SaaS team should choose a UX/UI agency that can show how it handles different user roles, onboarding dependencies, and daily work inside a complex product. Humbleteam, Eleken, and Lighthouse are candidates for product design. Conversion Factory is a more focused option when signup and onboarding experimentation are the central brief.
Humbleteam publishes this guide and includes itself in the comparison. The recommendations below use public case studies and service descriptions. They indicate relevant scope; they do not establish that one agency will produce a better result for every product.
Which UX/UI agencies suit B2B SaaS products?
| Provider | Published evidence | Scope to discuss |
|---|---|---|
| Conversion Factory | A dedicated SaaS onboarding service covering signup experiments and onboarding screens. | A focused conversion project involving design and marketing. Ask for relevant experiment results. |
| Eleken | Avid’s signup and onboarding redesign, separate nonprofit and agency routes, contextual errors, and a design system. | Redesigning onboarding within an existing SaaS product and team. |
| Humbleteam | SaaS work covering first use, dashboards, roles, and product design; the Quipli case documents brand and product experience. | A product redesign connecting onboarding, daily workflows, and the design system. |
| Lighthouse | Push Security product scoping, user flows, design-system components, and early onboarding. | A B2B team that needs its primary user and product scope clarified alongside design. |
Which agency is best for an onboarding redesign?
Shortlist by the failure the team needs to resolve. Eleken’s Avid case provides a concrete onboarding walkthrough. Conversion Factory explicitly offers signup and onboarding optimization. Humbleteam’s SaaS service includes imports, empty states, and first useful actions. Lighthouse’s Push Security case connects the product proposition to early use.
Lighthouse is now part of Digital Product People. Confirm the proposed delivery team when discussing its earlier cases.
Ask each provider to explain one comparable journey, its contribution, and how the result was assessed. A service page is enough to establish an offered scope; evidence of an improvement requires the starting measure, the change, the observation period, and any other changes that affected the result.
For a platform with several roles, a single signup flow can conceal different problems. The purchaser may choose the plan, an administrator may connect data, and a colleague may perform the task that makes the product useful. The proposal should cover the handoffs between them.
A useful paid selection exercise uses one shared scenario: an administrator starts an import, leaves before completion, and invites a colleague who cannot access the imported records. Ask each candidate to identify the missing evidence, map recovery, and explain what the product should preserve. The strongest proposal connects the steps across roles and names the technical dependencies. It does not merely redraw the signup screen. The guide to recovering from a failed data import gives that exercise a more detailed set of mapping, partial-success, and retry states.
How does the buyer-user split change product design?
A buyer may evaluate reporting, integration, and administrative control, while a daily user needs to finish a task quickly. Map both journeys. A sales demonstration should make the intended value understandable; the working interface must support the actions and exceptions behind that demonstration.
In the Quipli case, Humbleteam describes a unified rental software product and the brand and product experience around it. Rentals, maintenance, orders, and inventory provide a concrete product context for a portfolio conversation. The public case does not provide a measured onboarding uplift, so buyers should request additional evidence for that specific outcome.
What should the onboarding brief measure?
Separate creating an account from experiencing value. A proposed milestone for a reporting product could be publishing a report using the customer’s own data. An account created with no successful import would not meet that milestone.
Lenny Rachitsky’s guide to choosing an activation metric discusses user-level actions alongside workspace-level adoption. Apply that distinction when one person configures the product and another needs to use the result. A rise in completed signup forms may coexist with stalled team adoption.
| Situation | Design question | Evidence to collect |
|---|---|---|
| An administrator starts an import | Can the person understand progress, errors, and what happens after leaving? | Import completion and recovery observations |
| A colleague accepts an invitation | Can that person find a useful task without repeating setup? | First useful action by role |
| The workspace has no customer data | Can users distinguish a demonstration from their actual results? | Understanding of sample data and the next required step |
| A user returns after an interruption | Does the product preserve completed work and show the remaining dependency? | Resumption, task completion, and requests for help |
This is a proposed test framework, not a client result. Adapt the situations to the product, agree on event definitions, and review the current experience before changing it. Compare equivalent signup cohorts and keep qualified activation, support demand, and existing-user task completion visible. A faster signup that attracts the wrong accounts or disrupts current customers may be a poor tradeoff.
What else should the agency understand beyond onboarding?
A successful first session leads into daily work. Test dashboards with realistic data volumes, restricted roles, long labels, empty results, and bulk actions. Organize information around the decisions users need to make. Copying the database structure into navigation can leave a technically complete product difficult to use.
The design system should cover recurring behavior as well as colors and components: table sorting, validation, permissions, interrupted tasks, and changes that affect several records. Ask which decisions the agency documents and which components the development team will maintain.
Users switching from established SaaS products bring familiar habits. Research which shortcuts and conventions should stay familiar and where the new product should make a different tradeoff. The most useful redesign may be a narrower task with a clearer outcome, rather than a visual imitation of the incumbent.
What should be agreed before work begins?
The brief should name the journey, target roles, available analytics, research access, implementation owner, and release constraints. The agency proposal should identify its team, deliverables, testing plan, and support during development. Clarify whether the assignment includes brand, product design, engineering, or only part of that work.
For a focused first engagement, request a diagnosis of the failing journey and a tested proposal for it. The guide to startup onboarding provides further questions for that brief. London teams can also compare the UX audit and activation shortlist. Discuss a SaaS design assignment with Humbleteam.
