Jeff Bezos

Jeff Bezos, before becoming the world's richest person, was a prolific angel investor who put $250,000 into Google in 1998—a 1998 stake worth over $3 billion by 2004—and backed Uber, Airbnb, and Twitter in their earliest rounds. His Google check alone returned roughly 12,000x, actually beating Andy Bechtolsheim's 10,000x multiplier from the same company. However, Bezos's angel activity was more selective than #3 Ron Conway: Conway made 700+ seed bets compared to Bezos's handful, which underscores Bezos's focus on high-conviction, low-volume decisions. Bezos's 1998 Google investment remains the single largest percentage gain on this list for any individual, demonstrating his knack for atomic bets on transformative technology.
