New York Knicks star Jalen Brunson and his family are launching Thirty Third Management Group, a family-owned brand advisory firm that will manage his off-court business and represent clients across professional sports, business, and philanthropy, as first reported by NBA insider Chris Haynes.
"My family has been with me every step of the way, and everything we do is rooted in trust," Brunson said. "Thirty Third gives us the chance to take ownership of my off-court business, to build something that reflects who we are, and to do it together."
According to the same report, Brunson's mother, Sandra Brunson, will serve as president of the company.
His sister, Erica Brunson, has been named Director of Client Services, while Connor Cashaw will serve as Director of Business Development.
Brunson expands off-court business after title season
This move comes after the biggest season of Brunson's career. He averaged 26.0 points, 6.8 assists, and 3.3 rebounds during the 2025-26 regular season before leading New York to its first NBA championship in 53 years.
Brunson was also named 2026 NBA Finals MVP after averaging 32.6 points, 4.6 assists, and 4.2 rebounds against the San Antonio Spurs. He scored 45 points in the title-clinching Game 5.
The 30-year-old is a three-time NBA All-Star and has spent the last four seasons with the Knicks after beginning his career with the Dallas Mavericks.
