Context & Analysis

Causa Prima's founders bring payments and fintech backgrounds. Maex Ament began his career as a software engineer at SAP SE and later founded Taulia in 2009, a supply chain finance company, before starting Centrifuge in 2017. Henrik Gebbing spent three years at McKinsey & Company before cofounding Finoa in 2018. The two met in Madrid nearly a decade ago while pitching earlier startups, and later brought in Philip Stanislaus, who had led engineering under Ament at Centrifuge, as chief technology officer.

The company was founded early this year after the three realized internal corporate AI agents were still getting stuck waiting days for humans to answer emails. Its name comes from the Latin term for "first cause," reflecting Ament's philosophy that the root cause of all business is simply getting paid.

Base10 general partner Rexhi Dollaku said in a written statement that every dollar going into accounts payable and accounts receivable automation today assumes the bottleneck sits inside one company, while Causa Prima is building for the handoff between companies.
