Dan joined a successful early Internet service provider that sold in 1998, founded and failed by 2000 with a venture-backed roll-up in Asia, and then started M5 Networks. As CEO, Dan grew M5 into a pioneer in the cloud communications industry. After 12 years, he sold the company to ShoreTel (SHOR). During a sabbatical with his family in Barcelona, and a Henry Crown Fellowship at the Aspen Institute, Dan developed Circles, a video platform to make it easy for small groups to help each other work and grow. Today Circles is used by schools like Harvard Business School, Companies like Square and Banker’s Life, and communities like Millennium Schools and YPO.
