Felicis portfolio companies in San Francisco

Felicis’s San Francisco portfolio is one of the most active recruiting pools in the market. The list above ranks Felicis-backed companies headquartered in San Francisco by current headcount, drawn from public LinkedIn and Crunchbase records. With 120 matching companies in Refolk’s index, you can see exactly where the Felicis thesis has landed locally.

Felicis companies in San Francisco tend to attract a specific type of operator - a founder or early hire bought into both the firm’s thesis and the city’s ecosystem. That makes the engineers and designers at these companies particularly valuable signals.

Refolk lets you reach this pool. Ask for “Felicis companies in San Francisco hiring founding engineers” or “founders of Felicis-backed companies in San Francisco who left in the last year” and Refolk returns a ranked shortlist with evidence behind each match.
