John Gleeson

John Gleeson is the Founder and General Partner of Success Venture Partners, a $10M seed-stage venture firm in San Francisco laser-focused on the post-sales customer success space. A Canadian-born operator who scaled customer success from $1M to $300M+ ARR at KeepTruckin (now Motive), John built the world's largest Customer Success Meetup communities in San Francisco and New York before turning his practitioner network into a differentiated LP base of over 87 Chief Customer Officers from companies like Slack, GitHub, Braze, and Notion. He bets on founders who are obsessively close to their customers, treating customer success not as a support function but as the primary engine of enterprise value.
