Capsa AI has raised $18 million in Series A funding to expand its artificial intelligence platform built for the private capital industry. The company, founded in the United Kingdom in 2023 and based in London, England, announced the round on June 10, 2026.
The financing was co-led by TX Ventures and Pivot Investment Partners, with participation from Bek Ventures and continued backing from existing investors Outward VC, Antler and Cornerstone VC. A group of angel investors also joined, including Indeed co-founder Paul Forster. The new money brings Capsa AI’s total funding to $20 million.
Capsa AI is building what it describes as an AI operating system for private capital firms. The core idea is to help these firms capture, organize and use institutional knowledge, which the company argues is one of the most valuable and most overlooked advantages in private markets. Its platform is designed to preserve and compound the knowledge that accumulates across transactions, so the system grows more capable with every deal a firm completes.
The raise follows a stretch of strong commercial results. The company reported a 100% customer renewal rate, net dollar retention above 122%, and 14x year-on-year growth in annual recurring revenue. Those figures point to customers not just staying but spending more over time, which tends to draw investor attention in the fintech space.
Capsa AI plans to put the proceeds toward expanding its presence in the U.S. market, growing both its engineering and go-to-market teams, and continuing to develop the platform’s agentic and indexing capabilities. The push into the U.S. is notable for a company that has so far built its base in the United Kingdom, and it signals where Capsa AI sees the largest pool of private capital firms to serve.
