Spencer Rascoff

Spencer Rascoff founded his family office in 2019, the same year he exited as CEO of Zillow Group. The firm manages the wealth Rascoff generated as a co-founder and long-time leader of the real estate technology company, which went public in 2011 and grew to a market cap exceeding $10 billion during his tenure. Rascoff has described the office as a vehicle for active direct investing rather than passive wealth management. The office focuses on early-stage venture capital, concentrating on Seed and Series A rounds across technology verticals aligned with Rascoff's expertise. Documented sector exposures include PropTech, SpaceTech, HRTech, FinTech, and Digital Health. The firm makes direct investments and occasionally participates in special-purpose vehicles alongside other family offices. Portfolio companies revealed through public filings include space infrastructure startup Astrolab and HR platform Fountain. Geographically, all known investments target North American companies. Team size and staffing details have not been disclosed publicly. The office maintains its headquarters in Menlo Park, California. In 2023, Rascoff joined the advisory board of R360, a membership organization for ultra-high-net-worth families, signaling an interest in peer networks. No philanthropic foundation has been publicly associated with the entity. The office's structural differentiator is its operator-led model: Rascoff takes board seats at portfolio companies and uses his experience scaling Zillow to advise founders. His prior roles as a technology executive and his deep network in real estate and consumer internet give the office a sourcing pipeline that competes with institutional venture firms.
