Bio
John Kosner is an internet pioneer and four-decade veteran of sports media. Today, he is an investor and advisor in sports tech startups and president of Kosner Media, a digital media and sports consultancy.

In 2018, John and the late NBA Commissioner Emeritus David Stern created Micromanagement Ventures, a portfolio of sports technology start-ups focused on media, betting and player health. John continues to serve as an advisor to and an investor in 10 of the original Micromanagement Ventures portfolio companies which include WHOOP, WSC Sports, Overtime and Bit Fry Game Studios.
