Summary List PlacementTwo Sigma's expansion into the private markets has added another arm. Two Sigma Real Estate is the $58 billion quant giant's newest unit and will be led by Tom Hill, the former Blackstone executive who joined Two Sigma in 2019 as a consultant, and Rich Gomel, a former managing director at WeWork who led the firm's real-estate investment platform. This is the fourth private investing business Two Sigma has built, and second since Hill joined the firm.
