infrastructure connecting private markets.
In an increasingly complex landscape of private fund structures, the complete absence of standardization is costing the industry billions in lost efficiency while millions of investors remain blocked from participating in an entire asset class. A shared infrastructure for the global private funds industry — serving all participants through a single point of access — is essential to move private capital with precision and at the speed of opportunity.
Private capital moves at institutional scale — yet every instruction, confirmation and settlement still travels across fragmented systems. FundStream brings that volume onto one synchronized, standardized network where every participant connects once and reaches everyone.
Global transaction volumes across private‑fund markets, including 9,118 deals in the Americas and 8,278 in Europe
Global private capital raised across all private asset classes reached new highs, fueled by demand for AI-driven infrastructure such as data centers
