New York Knicks captain Jalen Brunson is expanding his vision beyond basketball with the launch of Thirty Third Management Group, a family-owned brand advisory firm based in New York.

The company, announced September 16, 2026, will manage Brunson’s off-court business interests while also advising athletes, NIL talent, entrepreneurs, executives and charitable organizations on branding, partnerships, business development and philanthropy.

A Family Business

Brunson is building Thirty Third alongside people who have been part of his journey for years. His mother, Sandra Brunson, serves as president, while his sister Erica Brunson is Director of Client Services. Longtime friend and former teammate Connor Cashaw serves as Director of Business Development.

The name Thirty Third comes from Brunson being selected 33rd overall in the 2018 NBA Draft.

The company also plans to make women’s professional sports an early priority, with Erica Brunson leading that initiative.

Building Beyond Basketball

For Brunson, the venture represents another step toward building something that can extend beyond his NBA career. Instead of simply managing endorsements, Thirty Third gives the Brunson family its own platform to develop brands, partnerships and long-term business opportunities.

Thirty-three marked the beginning of Jalen Brunson’s NBA journey. Now, Thirty Third represents what the Brunson family is building for the future.
