StepStone Group is a private-markets investment manager whose venture and growth platform spans seed through growth equity, combining fund investments, direct investments and secondaries.

Its direct investment practice uses relationships with venture and growth fund managers, proprietary data and a global team to evaluate companies. This sits alongside its role as an investor in those managers’ funds.

The platform can participate in new company financings and in secondary transactions involving existing ownership. Founders should distinguish the capital needs of the business from shareholder liquidity when considering which part of StepStone’s investment model is relevant.
