Philip Black co-founded one of the earliest institutional seed funds at True Ventures, designed from day one to write small initial checks while thinking in terms of very large long-term outcomes, and he evaluates startups using four distinct categories of risk that he maps each company against as part of his structured investing approach. He's known for backing iconic product-centric companies like Fitbit, Peloton, and Automattic at the very earliest stages, focusing on founder gravity and consumer resonance rather than just financial metrics, and he coaches founders using his principle that great startup CEOs should make reversible decisions quickly and irreversible decisions thoughtfully.
