Maximizing athletes’ potential

GSI is a global baseball agency providing individualized representation, career strategy, and NIL advisory services to professional and collegiate athletes. We represent players and coaches across MLB, MiLB, and international markets, and advise college athletes navigating Name, Image, and Likeness opportunities with a long-term professional lens.

Unlike volume-driven agencies, GSI operates with a career-first approach – prioritizing performance, market positioning, and sustainable earning potential. Our goal is to help clients build lasting careers and create generational growth for themselves and their families.
