Brian Acton
Brian Acton is the co-founder of WhatsApp, which sold to Facebook for $19 billion in 2014, and the founder of Signal Foundation, where he champions privacy-focused communication. After walking away from $850 million in unvested Facebook stock over ethical disagreements about user privacy, he invested $50 million to build Signal, an encrypted messaging platform designed to put users first. A Stanford computer science graduate who was rejected by both Facebook and Twitter in 2009, Acton has given over $1 billion to charitable causes with his wife Tegan, focusing on low-income families, reproductive rights, and internet privacy.
