Capsa AI, the London and New York-based startup building the AI operating system for private capital, has raised $18m (£13.4m) in a Series A round.
The round was co-led by TX Ventures and Pivot Investment Partners, with significant participation from Bek Ventures.
The round closes on the back of a 100 per cent customer renewal rate and 14x year-on-year ARR growth.
Capsa AI was founded by Danyal Ozduzenciler and Callum Downie.

Oezduezenciler brings over seven years of experience working in private equity and investment banking, including roles at AEA Investors, Citi, and Deutsche Bank, during which he participated in more than 50 due diligence processes.
Downie has a proven track record of leading machine learning teams and developing AI products from the ground up, with experience spanning the full machine learning lifecycle at companies including ThirdEye Labs and Standard AI.
Capsa AI’s technology is already in use at several of the world’s largest private capital firms, with further major enterprise deployments rolling out across the US and Europe.
Capsa AI’s growth accelerated rapidly this year when the UK startup opened a New York office, with CEO Danyal Oezduezenciler permanently relocating to the US.
The team stands at 14 people across London and New York.
All existing institutional investors have reinvested in the Series A, including Antler, Outward VC, and Cornerstone VC, alongside industry angel investors from leading private capital firms and tier-1 US operators, including Paul Forster, co-founder of Indeed.
Rather than bolting AI onto existing workflows, Capsa embeds it as infrastructure across the full fund lifecycle: sourcing, due diligence, portfolio monitoring, and back-office operations.
Across leading private capital firms, Capsa indexes millions of internal sources and tens of thousands of deals – every memo, conversation and decision a firm holds – making decades of institutional knowledge instantly searchable for the first time.
Ozduzenciler, CEO and co-founder of Capsa AI,said: “Private capital is one of the most data-intensive industries on earth, and it has been chronically underserved by technology.
“We set out to build the platform that changes that – one that encodes how a fund thinks and operates and then executes on it.
“We’re bringing world-class AI to private capital, and the support of TX Ventures, Pivot Investment Partners, Bek Ventures, and all of our existing investors will allow us to scale what we’re building even faster.”
Funding from the Series A raise will be deployed into US market expansion, hiring across engineering and go-to-market, and further investment in the platform’s agentic and indexing capabilities.
