Jonathan Heiliger brings unusually deep large-scale systems experience to venture capital, having run global infrastructure at Facebook during its hypergrowth from 35 million to over 800 million users and previously built infrastructure at Yahoo and ISPs before becoming an investor at Vertex Ventures. He's known for his counseling-style approach with founders, focusing on their emotional journey and personal growth as much as the business, and for his philosophy that when you raise capital, you're buying speed, not time.
