DFX Intelligence

Allocator Intelligence

The capital-owner graph behind private markets. Who owns the capital, who decides, how much, under what policy, on whose advice, to which managers, and what changed, with a source and a date behind every row. A target is never an actual, a disclosed holding is never an approval, and an estimate says so.
