Peter co-founded ExpressVPN in 2009, bootstrapping the company from its earliest days, writing much of the code himself and growing it into one of the world's most recognized VPN providers with over 4 million paying customers. He and his co-founder maintained 50-50 ownership from launch through the company's sale for $936 million in 2021, a rare outcome in any exit. Today Peter invests in and mentors entrepreneurs through his firm, Titanium Birch.
