Ranked agencies for B2B clients
About this list
Barcelona's B2B roster concentrates on the marketing and conversion surface of B2B software — the sites and systems that turn a complex product into signups, often for international clients. Embacy documents brand identity and Webflow sites for fintech, SaaS and crypto; BRIX evidences conversion-focused Webflow sites and design systems for SaaS and AI companies; BRICX names US-based AI and SaaS startups needing MVP and conversion work.
That gives the roster a specific shape: fast, conversion-oriented B2B web and design-system work rather than deep workflow research. Rates run €25–150 per hour, with the Webflow-and-systems shops in the mid band. Novicell adds Iberian B2B lead-generation and conversion depth.
This is a strong list for a SaaS or AI company that needs a credible B2B site, a design system and a converting funnel; it is a weaker fit if your problem is a dense internal workflow. Read each profile's documented B2B clients for whether the work is the product itself or the site that sells it — both are legitimate, but they are different buys, and the editorial review makes the distinction clear.
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.
