Jung-Hong Kim
Co-founder & CEO, Klipy
Jung-Hong Kim is the co-founder and CEO of Klipy, the AI CRO for owner-led B2B teams. He has spent over 15 years in B2B technology and builds Klipy while running its sales himself, the same owner-seller he builds for who still closes and delivers the work. He writes about sales follow-up, speed-to-lead, and running a founder-led sales motion without an SDR team, grounded in what actually works when the person selling is also the person doing the delivery.
Klipy turns your real conversations into ready-to-send follow-ups, drafted through proven sales frameworks, and you approve every one.
