Agent-native infrastructure. Loved by builders.

Used by AI engineers, SaaS builders, and procurement teams across Europe.

“The MCP integration with Claude is seamless. Our procurement agent answers sourcing questions in seconds — directly from structured btob.dev data. We went from manual research to automated in a weekend.”

Andrei M.

AI Engineering Lead · B2B SaaS, Romania

“This is the first EU-focused supplier API I've found that isn't behind a €50K contract or just a scraped directory with no structure. The NACE code taxonomy alone is worth integrating.”

Lars K.

CTO · Procurement Software, Norway

“btob.dev cut our supplier discovery time from three weeks to under two hours. The search filters actually work — NACE code, country, size. Nothing else does this for European suppliers.”

Emma R.

Head of Procurement · Industrial Manufacturing, DE

“We plugged the API into our KYC pipeline. Sub-100ms response with structured company data including VAT and legal status. Replaced two manual lookup steps overnight.”

Sophie L.

Compliance Lead · Fintech, France
