About this list
B2B products fail differently than consumer ones: the buyer isn't the user, workflows run six hours a day rather than six minutes, and "engagement" means fewer clicks, not more. The agencies on this page have documented B2B work — each lists at least two named, published engagements designing products that businesses buy: SaaS platforms, industrial and logistics tools, professional services, developer tooling.
We classify by the engagement's context first: what the designed product actually serves. An agency earns the B2B chip when at least two documented engagements were products sold to businesses — the client's own revenue model is only the fallback when the engagement context isn't public. Genuine two-sided businesses (marketplaces) can legitimately count toward both B2B and B2C, but a consumer conglomerate whose documented engagement was an internal business tool earns B2B credit, not B2C.
B2B design competence shows up in unglamorous places: information density that respects power users, permission models and admin surfaces, data tables that survive real datasets, onboarding that works for a procured tool the user didn't choose. Portfolios full of marketing sites and consumer apps predict none of that. If you're building a SaaS product specifically, the SaaS industry page complements this list with vertical depth; this page cuts across industries by business model. Selling to enterprises specifically? The enterprise page filters by client size instead.
Expert Insight
Why B2B fit matters
The buyer/user split defines B2B UX: agencies without documented B2B work consistently design for the demo, not the daily workflow.
Information density is a discipline — B2B users live in these tools; consumer-style whitespace and mobile-first patterns actively hurt them.
Admin surfaces, permissions, and integrations are where B2B products win deals; documented B2B engagements are the only evidence an agency has built them.
Business-model fit compounds with vertical fit: cross-reference this page with the industry pages (SaaS, FinTech, Healthcare) to find agencies matching both.
Frequently asked questions
Documented engagements designing products sold to businesses — SaaS platforms, industrial and logistics software, professional services, developer tools. We classify by the engagement's context (who the designed product serves), not the client's brand: at least two named, published B2B engagements per listed agency, with two-sided marketplaces allowed to count toward both B2B and B2C.
The buyer isn't the user, so success means workflow efficiency, not engagement time. B2B interfaces need information density, keyboard-speed interaction, permission and admin models, and integration-heavy flows — and they're procured, so onboarding must work for users who never chose the tool. Agencies on this page evidence exactly that kind of work.
Both axes matter. This page filters by business model; the industry pages (SaaS, FinTech, Healthcare and others) filter by domain. The strongest shortlist usually comes from the intersection — an agency with documented B2B work in your vertical. The combo pages linked below list exactly those intersections where enough verified agencies exist.
