Jalen Brunson Launches Family-Run Brand Advisory Firm

New York Knicks star Jalen Brunson has launched Thirty Third Management Group, a family-owned brand advisory firm designed to manage his off-court business and represent other clients. The company, announced on September 16, 2026, is named after Brunson's 33rd overall selection in the 2018 NBA Draft by the Dallas Mavericks. The firm will handle brand development, partnerships, business development, and philanthropy for athletes, NIL talent, executives, entrepreneurs, and charitable foundations. Brunson will be the firm's foundational client, but the venture aims to grow beyond his personal portfolio. An early priority will be building a practice dedicated to women's professional sports. Leadership roles within the company are filled by Brunson's family and a longtime friend. His mother, Sandra Brunson, who has managed his off-court business for eight years, serves as president. His sister, Erica Brunson, is director of client services and will lead the women's sports initiative. Connor Cashaw, Brunson's high school teammate, is director of business development.
