Sun joined Ripple Labs as a chief representative and adviser in Greater China at the end of 2013, according to his LinkedIn page. He worked at the cryptocurrency startup — which has received backing from Google Ventures, Andreessen Horowitz, and other blue-chip investors — for just over two years. Sun also founded Callme or Peiwo, China's largest voice live-streaming app, in 2013.
In July 2017, Sun founded the Tron Foundation, a blockchain company with its own cryptocurrency that is "dedicated to building the infrastructure for a truly decentralized Internet," his LinkedIn page states. Less than a year later, Tron acquired BitTorrent, a peer-to-peer file-sharing service, for around $126 million, according to TechCrunch. Sun currently serves as CEO of Peiwo, Tron, and BitTorrent.
