Brunson, who recently won the 2026 NBA Finals MVP award, is taking a similar approach to controlling his off-court interests, but with his family at the center of the operation, as reported by EssentiallySports.

Sandra Brunson, Brunson's mother, will serve as president of the company, while his sister Erica Brunson has been named Director of Client Services, and Connor Cashaw will serve as Director of Business Development, according to EssentiallySports.

The move comes after Brunson had his biggest season, averaging 32.6 points, 4.6 assists, and 4.2 rebounds during the NBA Finals against the San Antonio Spurs, as reported by BasketNews.com.

The company is also targeting college athletes who make money from their name, image, and likeness (NIL), a market that has exploded since the NCAA started allowing such deals in 2021, according to Baller Alert.

The name of the company has a clear connection to Brunson's NBA story, and the firm aims to grow well beyond him, with plans to advise other clients in the future, as reported by EssentiallySports.
