Capsa AI, a London and New York startup building what it calls an “AI operating system” for private capital, has raised $18M in Series A funding. The round was co-led by TX Ventures and Pivot Investment Partners, with participation from Bek Ventures, and takes the company’s total raised to $20M.

Every existing institutional backer reinvested, including Antler, Outward VC, and Cornerstone, alongside angels such as Indeed co-founder Paul Forster.

Founded in 2024, Capsa indexes a fund’s scattered data, the CRM entries, Outlook threads, SharePoint files, and deal memos, into a single searchable layer. The pitch is that decades of institutional knowledge, currently locked in PDFs and inboxes, become instantly queryable, with agentic AI running across sourcing, due diligence, portfolio monitoring, and back-office work.

The underlying problem is real. Private capital manages more than $15tn in assets, the company says, yet much of it is still tracked in spreadsheets and email, and investment staff lose hundreds of hours a year to manual search, a drag Capsa puts at $35bn a year across the industry.

Assets have tripled since 2015 while data volumes keep doubling, and teams have not grown to match.The 💜 of EU techThe latest rumblings from the EU tech scene, a story from our wise ol' founder Boris, and some questionable AI art. It's free, every week, in your inbox. Sign up now!
