Note: Founded in 2024 by former private equity investor Danyal Özdüzenciler (AEA Investors, Citi, Deutsche Bank) and machine learning specialist Callum Downie (ThirdEye Labs, Standard AI), Capsa AI has engineered an AI-powered operating system custom-tailored for the global private capital industry. While the sector manages over $15 trillion in global assets, critical investment data remains heavily fragmented across opaque PDFs, unstructured emails, and isolated spreadsheets, costing analysts over 500 hours annually in manual compliance entry and deal search. Capsa's model-agnostic, SOC 2 Type II certified platform unifies and structures a fund's entire data estate—indexing every memo, conversation, and historic deal team decision into a single knowledge layer. Operating on a single-tenant deployment architecture with localized data hosting, the platform has seen explosive traction, closing the round on the back of a 14x year-on-year ARR expansion, a 100% customer renewal rate, and net dollar retention exceeding 122%. The fresh $18m funding will fuel structural hiring across engineering and go-to-market functions, expand product agentic indexing pipelines, and heavily back their rapid US market footprint following the permanent relocation of its CEO to their newly opened New York headquarters.
