Previously, Michael led digital media and business development across the portfolio of 22 FOX regional sports networks. He joined YES Network beginning in 2006, helping build and ultimately sell the business to FOX for $3.8BN in 2014. While at YES, Michael was responsible for several initiatives including launching the first ever authenticated streaming product in U.S. sport.

Personally, Michael has served as an early stage investor in and advisor to Bonobos, Trunk Club, Tecovas, Billie, RotoQL, Drone Racing League, Overtime, Cargo and Boom.

Michael graduated magna cum laude from Amherst College, where he played football and baseball, with a bachelor’s in economics, and from the Stanford Graduate School of Business, where he played dodgeball and led the GSB Show, with an MBA. Michael was named to the Multichannel News 40-under-40 list in 2010 and is a two-time Emmy winner who enjoys reading, fitness and traveling. A native Rhode Islander, Michael splits time between New York and the Bay Area.

At Overtime we love our partnership with Sapphire and Michael, particularly as he helped our latest round come together and was a constant source of encouragement. Sometimes it’s those intangibles, that energy, that belief, that keep you going. Having a partner that doesn’t just write you a check, but believes in you and sticks their neck out and brings other people to the table – that was really, really critical for our business.
