Jon founded his first company, Mountain Bike Outfitters, Inc in 1986. He started his venture career as an associate at Summit Partners and then joined AOL’s Greenhouse, the venture capital/incubator for AOL. Jon joined the internet market early by joining CMGi’s @Ventures group in 1996. Before founding True, Jon was a Managing Director at Globespan Capital.
