Capsa AI, a London and New York-based startup developing an AI operating system for private capital, has closed an $18m Series A funding round, bringing its total raised to $20m.
The round was co-led by TX Ventures and Pivot Investment Partners, with significant participation from Bek Ventures.
All existing institutional investors reinvested, including Antler, Outward VC, and Cornerstone VC, as well as angel investors from leading private capital firms and tier-1 US operators, among them Paul Forster, co-founder of Indeed.
The raise follows strong commercial performance, including a 100% customer renewal rate, net dollar retention exceeding 122%, and 14x year-on-year ARR growth.
Proceeds from the Series A will be directed towards expanding Capsa AI’s presence in the US market, growing its engineering and go-to-market teams, and further developing the platform’s agentic and indexing capabilities.
Capsa AI was founded in 2024 by Danyal Oezduezenciler and Callum Downie. The platform embeds agentic AI across the complete fund lifecycle, covering sourcing, due diligence, portfolio monitoring, and back-office operations, and is built on a model-agnostic, SOC 2 Type II certified architecture with single-tenant deployment options, regional data hosting, and no training on client data.
Capsa AI CEO and co-founder Danyal Oezduezenciler 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.”
TX Ventures partner Krzysztof Bialkowski said, “Private capital is one of the largest knowledge-work markets still running on fragmented documents, emails and siloed systems. We invested in Capsa because the team is building a purpose-built intelligence layer for how funds source, diligence and monitor investments – not a generic AI copilot.
“The product compounds with every workflow and every piece of institutional knowledge captured, which is exactly the kind of vertical AI infrastructure we believe will define the next generation of financial services software. Danyal, Callum and the team have shown exceptional customer pull, capital efficiency and enterprise-grade execution, and we are excited to support them as they scale across Europe and the US.”
