Caplight Technologies has closed a $16 million Series A led by BlackRock and Fin Capital, with LEAP Global Partners as a new co-lead investor and UBS Investment Bank participating strategically. The San Francisco-based company said the funding will support expansion across private market data and agentic workflows for research and transactions. Caplight operates a platform focused on venture secondary data and private market infrastructure. The company says its system includes 100,000 company and investor profiles, $4 trillion in funding round data, more than $300 billion in proprietary secondary data, and more than $5 billion in daily live transaction flow. It said customers collectively manage more than $52 trillion in assets and access the platform through its interface, API and MCP server. The investment also sets up a framework for future collaboration with BlackRock across its private markets and technology ecosystem, including Aladdin and Preqin. Caplight said private markets have grown into a more than $12 trillion asset class over the past three years, increasing demand for better data, transparency and secondary market liquidity.
