Jules LangeardPrograms Director, Station F“We want founders to walk in with their hands in their pockets and walk out having cold called a list they built just before. In our demo, Pipecorn found 89 mobile numbers in under 20 minutes. It's exactly what we're looking for, simple and fast.”

Ksenya BorzovGTM Manager, OSS Ventures“On the same list, Pipecorn found more mobile numbers than Zeliq, so my choice was quick. With the Pipecorn MCP in Perplexity, I now build the lists we used to pay €1,500 a month for. I think all our companies will move to Pipecorn.”

Edson KouebiLead Growth, Iconoclass“We called every number from four tools three times in 48 hours. Pipecorn came first on numbers that picked up, ahead of FullEnrich and Zeliq, when the whole team expected Zeliq to win.”

Antoine VermesseFounding GTM, Covera“I connected Pipecorn to Claude through the MCP and was fully set up in 15 minutes. Now I build our lists in Claude and enrich them through the API, with no SDR team.”

OSS Ventures
Malo BrinquinGTM Engineer, Bonx“We didn't replace Clay — we filled the gap Clay couldn't. Pipecorn found the Italian manufacturers Clay didn't index, with phone numbers that actually rang. +6 meetings per rep in a market we couldn't crack before.”Read the case study →
