Roger Ehrenberg built his reputation through a concentrated reserve strategy at IA Ventures, typically backing 22-25 companies per fund but putting the majority of capital into 5-7 breakouts like The Trade Desk and Wise, then aggressively recycling early liquidity to drive 10x+ net returns. After stepping back from IA Ventures, he has evolved into a specialized sports and entertainment investor with minority ownership stakes in major franchises including the Miami Marlins, Real Salt Lake, and Alpine F1, while building a multigenerational family investment enterprise where he and his wife lent capital to their sons to invest alongside him.
