Madrid-based Causa Prima raised a $20M seed led by Base10 Partners, three months after a $10M pre-seed, to build AI agents that settle business invoices.
Key Takeaways
- Causa Prima raised a $20M seed on October 13, 2026, led by Base10 Partners, with no valuation disclosed.
- The round follows a $10M pre-seed from June 2026 and lifts total funding to $30M.
- The company has 25 employees across Madrid and Munich and plans a New York office.
Lead
Causa Prima, a fintech headquartered in Madrid with a second team in Munich, announced a $20 million seed round on October 13, 2026. Base10 Partners led the financing. QED Investors and FJ Labs joined as new backers, while Creandum, Kfund and Borusan Ventures reinvested.
The company builds software in which AI agents represent a buyer and a supplier on a shared network. They approve invoices, resolve disputes, negotiate payment timing and offer early-payment discounts. Valuation was not disclosed.
What Does Causa Prima Actually Do?
Causa Prima sells an agent-to-agent network for business-to-business finance. One agent acts for the paying company and another for the supplier, and the two settle questions that normally pass between accounts payable and accounts receivable teams by email and phone.
Those questions include whether an invoice matches a purchase order, why a payment is late, and whether a supplier will accept a discount for faster payment. The company says it has more than 3,000 active accounts and is onboarding multibillion-dollar enterprises. It has not said how many of those accounts are paying customers.
CEO Maex Ament framed the pitch this way: "The biggest inefficiency in corporate finance is no longer inside the company. It is between companies."
Who Is Behind It?
Ament is a former SAP software engineer who co-founded the invoice-financing firm Taulia in 2009 and later co-founded Centrifuge. Henrik Gebbing co-founded the crypto custody company Finoa in 2018 after three years at McKinsey. CTO Philip Stanislaus ran more than 600 enterprise security audits at Oak Security and previously led engineering at Centrifuge.
That résumé explains how a company launched in 2026 can claim an account base in the thousands. Founders with a decade of supplier-finance relationships start with introductions that most seed-stage companies lack. It also means the traction figure reflects the founders' history as much as the new product.
Why Did Causa Prima Raise Again So Quickly?
The company raised again because its first round was already large and its target market, the United States, is far from Madrid. The $10M pre-seed, announced on June 16, 2026 and led by Creandum, was billed as the largest pre-seed ever raised by a Spanish company. It funded product and engineering hires in Madrid and Munich.
A seed three months later, at twice the size, shows investors competing for the founders rather than waiting for revenue to prove the model. Both rounds came before any disclosed commercial milestone beyond the account count. The repeat participation of Creandum, Kfund and Borusan Ventures is the clearest signal that existing backers saw enough in three months to write more checks.
The money goes toward US expansion, including a New York office, and further platform development. The company says nearly half of credit-based B2B sales in the United States are overdue, citing research from credit insurer Atradius. A late-payment problem of that scale gives a negotiation network something concrete to sell against.
How Crowded Is B2B Payments Automation?
The field is crowded. Established vendors in accounts payable automation, supply chain finance and spend management already sell invoice matching and early-payment programs to the same enterprise buyers. Several of them are adding AI features to existing products.
Causa Prima's distinction is architectural. It places an agent on both sides of the transaction instead of automating one company's internal workflow. That approach only works if enough counterparties join the network, which is a harder sales problem than selling software to a single finance department. Network effects reward the first company to reach critical mass, and they punish the second.
What Are the Risks?
Autonomous agents moving money between companies raise questions of liability and control. Finance chiefs will want to know who is accountable when an agent approves a disputed invoice or grants a discount it should not have. The company has not published details on approval limits or audit trails.
The funding structure carries its own pressure. A $30M total raise at seed stage sets a high bar for the next round, and with no disclosed valuation, outsiders cannot judge how much of that bar is already priced in.
Outlook
Causa Prima has $30M in total funding, 25 employees and a plan to open in New York. What it has not shown publicly is revenue, customer concentration or how many network participants transact through its agents. The next test is whether enterprise buyers and their suppliers adopt the network in the US, and whether the 3,000-account figure converts into paid volume before the next funding round.
