What's the endgame? Causa Prima positions AI agents on both sides of a transaction — one company's accounts payable, the other's accounts receivable — to negotiate payment terms directly.

Where's it going? The startup has 25 employees across offices in Madrid and Munich and plans to use the funding to open a New York office as it enters the US market. It previously raised $10 million in a pre-seed round, bringing total funding to $30 million.
