Causa Prima raises $20 million seed led by Base10 for AI agents that settle invoices

The story so far, in brief; the legwork, and the full article, stay with the original outlets.

Causa Prima, a start-up founded in 2026 with offices in Madrid and Munich, has raised a $20 million seed round (about €17.88 million) led by Base10 Partners. QED Investors and FJ Labs come in as new investors, and Creandum, Kfund and Borusan Ventures, who backed the company before, have put in more. It arrives less than four months after a $10 million pre-seed, taking total funding to $30 million. The valuation was not disclosed.

The problem Causa Prima works on sits between companies rather than inside them: a buyer queries an invoice, the supplier chases the money, and an email thread grows for weeks. Its AI agents act for each side on a shared network, reconciling invoices, working through disputes and payment timing, and negotiating discounts for paying early. Chief executive and co-founder Maex Ament says finance teams "stop chasing and start deciding." The network counts more than 3,000 active accounts, the same figure the company gave in June, and it says it is now bringing on enterprise customers worth several billion dollars each.

Ament has been here before. He co-founded Taulia in 2009, in which SAP bought a majority stake in March 2022, and the company credits him with inventing dynamic discounting, the practice of trading early payment for a lower bill. He later co-founded Centrifuge, a platform for tokenised real-world assets. Henrik Gebbing co-founded Berlin crypto custodian Finoa in 2018 after three years at McKinsey, and chief technology officer Philip Stanislaus led more than 600 enterprise security audits at Oak Security. The company has 25 employees and will spend the money on expanding into the United States, where it is targeting trade credit, including a New York office, and on further work on the platform.
