Our Team

15+ years in the MLB agency business, representing some of the best players in the world, from top draft picks to seasoned big leaguers.

The agency was founded by Jonathan Weisz with one mission: helping players reach their maximum potential, at every stage of their career.

What separates Weisz Sports is intentional: deep negotiation experience built over almost two decades, a range of perspectives across the game, and a roster we keep small on purpose so every player gets real attention, not just a name on a client list.

Jonathan Weisz

FOUNDER / CEO

Jonathan brings two decades of experience as a certified MLB player agent and more than thirty years of entrepreneurial success, having led companies including SKLZ, iTarget, OnTech, and now Wagstaff Law / AUDITLab. His background in business, marketing, negotiation, and athlete representation serves as the foundation of everything we do.
