## Summary

Causa Prima, a Delaware-based startup founded by German entrepreneurs Maex Ament, Henrik Gebbing, and Philip Stanislaus, has closed a $20 million seed round led by Base10 Partners. The company develops an agent-to-agent AI platform designed to automate B2B payments, resolve billing disputes, and accelerate invoice processing between companies. This funding brings its total raised capital to $30 million, following a previous $10 million pre-seed round. Investors in the new round include QED Investors, FJ Labs, Creandum, Kfund, and Borusan Ventures, though Causa Prima did not disclose its valuation.

The platform addresses the inefficiency of manual approval processes in accounts payable and receivable. According to a 2025 report by Ardent Partners, nearly half of executives in these roles cite slow invoice approvals as their primary challenge, with average processing times exceeding eight days. Causa Prima’s agents negotiate directly with counterpart agents to facilitate early payments, monetizing the service by taking a percentage of the transaction. The company currently has 25 employees in Madrid and Munich and plans to open a New York office to expand its presence in the United States.

The founders, who met nearly a decade ago while pitching earlier startups, identified the gap in current AI automation, which often stalls when waiting for human intervention across organizational boundaries. They aim to build a network where agents handle the handoff between companies, targeting a market that Fortune Business Insights estimates at roughly $98 trillion in annual B2B payments.

## Key points

- Causa Prima raised a $20 million seed round led by Base10 Partners in September.
- The platform uses AI agents to automate B2B payments and resolve billing disputes between companies.
- Total funding reaches $30 million, with plans to open a New York office for US expansion.

## Why it matters

This funding supports the shift from internal AI agents to cross-organizational agent networks, potentially reducing the eight-day average delay in B2B invoice approvals and streamlining the $98 trillion global payments market.
