[Exponential Beers] Maex & Philip - Causa Prima

​​Exponential Beers, live in Madrid

​​​Exponential, in person in Madrid.

​​​​In this edition, we feature Maex Ament - co-founder Taulia (exited to SAP) and Centrifuge (one of the best protocols in crypto) - and Philip Stanislaus - founder of Oak Security. Between them, 10 startups, +$400M raised, and 2 unicorns.

​​​They are now building together Causa Prima, still running in stealth. Not many founders of this caliber in EU/Madrid. ​​​

​​​About Causa Prima

​$90T moves between businesses every year — most through manual data entry, spreadsheets, and email. 68% of companies still key invoices by hand; 80% of early-payment discounts go uncaptured.

​Enterprise software digitized the paperwork. It didn’t eliminate it. Causa Prima is building the agentic AI network for the Office of the CFO: specialized agents that reason, act, and coordinate across AP, AR, and treasury. Infrastructure, not chatbot.
