Causa Prima Pulls In $20M Seed Within a Quarter of Its Pre-Seed to Put AI Agents Between Buyers and Suppliers

Co‑founder and chief executive Maex Ament summed up the thesis by saying that the biggest inefficiency in corporate finance now sits between companies rather than inside them. The goal, he said, is for finance teams to stop chasing invoices and start making decisions, with full control and discount opportunities captured along the way.

The founding team has a long history in this corner of finance. Ament began as a software engineer at SAP and later co‑founded Taulia in 2009. The company credits him with inventing dynamic discounting, the practice of paying a supplier early in exchange for a reduced price. SAP completed the acquisition of a majority stake in Taulia in March 2022. He then co‑founded Centrifuge, a platform for tokenised real‑world assets. Henrik Gebbing co‑founded the Berlin digital asset custodian Finoa in 2018 after three years at McKinsey. Philip Stanislaus, the chief technology officer, previously led engineering under Ament at Centrifuge and ran enterprise security audits at Oak Security.

Causa Prima was founded in 2026 and operates from Madrid and Munich, with a team of about 25 people. It says more than 3,000 companies have joined its network, and that it has started onboarding large corporate customers with revenue in the billions of dollars. A network of that kind only works if both buyers and suppliers sign up, so early account numbers matter more here than they would for a single‑sided tool.

Rexhi Dollaku, general partner at Base10, explained the firm's reasoning in plain terms. Money flowing into payables and receivables automation today assumes the bottleneck sits within one company, he said, whereas Causa Prima is built for the handoff between them. Returning to the company three months after the pre‑seed, he added, reflects both the size of the problem and the speed at which the team is shipping.

Base10 describes its focus as automating the real economy, and its portfolio includes Nubank, Brex, and Instacart. QED Investors is a fintech specialist, while FJ Labs concentrates on marketplaces and businesses that benefit from network effects. That last point fits the product well, since every new buyer or supplier on the platform makes it more useful to the others.

The new capital will go toward expansion in the United States, including a planned office in New York, and continued development of the platform. Entering the American market will put the company in front of a much larger base of corporate buyers and suppliers, and also in front of better‑funded competitors.

Rivals are not hard to find. Stuut, a New York company that applies AI agents to order‑to‑cash processes for large enterprises, raised a $52.5 million Series B on October 7 led by Insight Partners, with Andreessen Horowitz also taking part. Most of the recent rounds in AI finance serve one side of a transaction, either the company chasing money or the company paying it. Causa Prima is betting that the more valuable position is the connection between them.

There are open questions. Payment terms are often set by contract and procurement policy, so agents negotiating invoice by invoice will need clear guardrails from finance leaders who are understandably careful about autonomy over cash. Large enterprises also move slowly on vendor onboarding, and a network product has to reach critical mass before the benefits become obvious. Security, auditability, and the ability to explain why an agent agreed to a discount or rejected a dispute will weigh heavily in enterprise buying decisions.
