You Mon Tsang
You Mon Tsang is the founder and CEO of ChurnZero, the Washington, DC customer success platform he started in 2015 to fix a blind spot he hit as a software CMO: companies knew everything about prospects and almost nothing about the customers they already had. A four-time software founder with prior exits at Biz360, Engine140, and Milktruck, Tsang has turned a single metric - net revenue retention - into a rallying cry for subscription businesses, arguing that product-market fit is not the ability to sell customers but the ability to keep them.
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.
