Causa Prima Raises $20M Seed Led by Base10 for Agent-to-Agent B2B Payment Negotiation

Delaware-based Causa Prima closed a $20M seed round led by Base10 Partners with QED, FJ Labs, Creandum, Kfund and Borusan Ventures, bringing total funding to $30M. The 25-person team (Madrid, Munich) builds an agent-to-agent platform that lets company AI agents negotiate payment terms and resolve billing disputes directly, taking a cut when early-payment deals clear. Founded in 2026 by Maex Ament, Henrik Gebbing and Philip Stanislaus; a New York office is planned.
