Michael Sachaj built his reputation at Hyde Park Angels by sourcing an unusually high number of deals—837 in under nine months—and by bringing a founder's eye to the job, having started a few companies himself in high school and college before working at Booz Allen Hamilton on Pentagon-related work and later finding his way into venture through a friend; he's also fluent in Polish. He tends to favor teams with multiple co-founders over solo founders, pays close attention to how AI might reshape the logistics and supply chain companies he focuses on, stresses the importance of having a champion inside an investor group to back a founder, and writes about using equity and option pools as tools for building fairer, more motivated teams.
