Arianna Simpson’s trip to Zimbabwe in 2013 changed her life. But it was the experience of using Western Union, and the platform’s extortionary fees, to send money to the family she sponsored that changed her mind on crypto. Now a general partner at Andreessen Horowitz, she helps to manage the massively influential venture capital firm’s $2.2 billion crypto fund. Simpson previously spent time at Facebook and BitGo. She’s also run her own investment funds, Autonomous Partners, which focused on digital assets, and Crystal Towers Capital, which worked with early-stage startups.
