Heron Rock

Heron Rock is a multi-family office investment platform based in the Bay Area, USA, enabling entrepreneurs to invest their capital in early-stage ventures and providing guidance to portfolio companies. The firm focuses on pre-validation stage opportunities, operating on a carried interest model that charges no management fees and earns solely from successful portfolio returns. Heron Rock maintains a portfolio of 32 current investments and has completed 45 prior investments, exclusively deploying capital from aligned individual investors rather than institutional sources. Notable activity includes leading an $11 million Series B funding round for Jumbotail in October 2020, following a prior $12.98 million Series B investment in the same company in November 2019. The platform aims for a limited number of significant outcomes annually from a concentrated deal flow. Heron Rock was founded by Tom Williams.
