Jalen Brunson Expands Off-Court Empire With Launch of Family-Led Brand Advisory Firm Thirty Third Management Group

New York Knicks star guard Jalen Brunson is taking a commanding step into the business world with the official launch of Thirty Third Management Group, a comprehensive, family-owned brand advisory and management firm headquartered in New York City. The venture is designed to consolidate Brunson’s expanding portfolio of commercial endorsements, business investments, and philanthropic endeavors under a single corporate umbrella. More importantly, it establishes a formal platform to extend high-level representation and strategic advisory services to outside clients, positioning the All-Star athlete not just as a marquee talent on the hardwood, but as an emerging entrepreneur and executive off it.
The founding of Thirty Third Management Group represents a growing paradigm shift in professional sports, where elite athletes increasingly seek to bypass traditional agency structures to build independent, family-led business infrastructures. By centralizing his commercial interests, Brunson is following a modern blueprint set by some of the sports industry’s most astute business minds, ensuring that his likeness, intellectual property, and long-term financial legacy remain firmly under his own control and the stewardship of his closest confidants.
From the 33rd Pick to a New York City Icon: The Origins of the Firm
The name Thirty Third Management Group is more than just a corporate moniker; it is a deeply personal nod to the foundational narrative of Brunson’s professional career. On June 21, 2018, following a decorated collegiate career at Villanova University where he won two NCAA national championships and earned consensus National Player of the Year honors, Brunson heard his name called 33rd overall by the Dallas Mavericks in the NBA Draft.
While being selected in the second round is often viewed as a steep climb in professional sports, Brunson used the perceived slight as fuel. Over the ensuing years, he evolved from a reliable bench contributor in Dallas into one of the most dynamic guards in the NBA. His high-profile move to the New York Knicks in the summer of 2022 transformed him into the undisputed face of one of the NBA’s most storied franchises, earning him multiple All-Star selections and cementing his status as a beloved New York icon.
The number 33 serves as a daily reminder of the persistence, grit, and strategic patience required to build long-term success—qualities that the leadership team of Thirty Third Management Group intends to instill in every client they represent.
A Core Team Built on Trust and Family Ties
Unlike traditional sports agencies that rely on sprawling corporate hierarchies and external executives, Thirty Third Management Group is built entirely upon a foundation of familial trust and lifelong relationships. The firm’s inaugural client roster includes Jalen Brunson himself, his wife Ali Marks Brunson, and his father, Rick Brunson, a former NBA player and current assistant coach for the New York Knicks whose guidance has shaped Jalen’s career at every level.
To manage the day-to-day operations and execute the firm’s ambitious strategic vision, Brunson has assembled a leadership team comprised of family members and trusted inner-circle associates:
- Sandra Brunson (Mother): Serving as President, Sandra brings invaluable organizational leadership and oversight to the firm, ensuring that the company’s foundational values remain intact as it scales operations.
- Erica Brunson (Sister): Appointed as Director of Client Services, Erica will oversee client relations and spearhead the firm’s high-priority initiative into women’s professional sports.
- Connor Cashaw (Friend and Former High School Teammate): Tasked with overseeing business development, Cashaw brings a lifelong personal connection and a sharp commercial eye to help identify emerging market opportunities for the firm’s roster.
To ensure the highest standards of corporate governance, compliance, and fiscal health, Thirty Third Management Group has retained premier external partners. The prominent law firm Meister Seelig & Schuster will serve as general legal counsel, while Focus Financial Partners has been brought on to advise the Brunson family on complex financial matters, asset management, and long-term wealth preservation.
Strategic Focus: Women’s Professional Sports and Underserved Markets
While Thirty Third Management Group is equipped to advise a diverse roster of professional athletes, high-potential Name, Image, and Likeness (NIL) collegiate talent, corporate executives, entrepreneurs, and philanthropic foundations, the firm’s leadership has already identified a clear initial priority: women’s professional sports.
In recent years, the sports landscape has witnessed an unprecedented surge in viewership, attendance, and media valuation across women’s professional sports leagues, most notably the WNBA and women’s collegiate basketball. However, despite this exponential growth in public interest, industry analysts and athletes alike have consistently pointed out that commercial infrastructure, marketing support, and corporate sponsorship opportunities have historically lagged behind the soaring demand.
Thirty Third Management Group aims to bridge this gap. Led by Erica Brunson, the firm’s initiative in women’s sports is designed to provide female athletes with specialized representation, sophisticated brand positioning, and lucrative commercial partnerships that match their cultural and athletic impact. By entering this space early, the firm positions itself not only as an advocate for gender equity in sports commerce, but also as an early mover in what financial analysts project to be one of the most lucrative growth sectors in the sports industry over the next decade.
The Broader Implications of Athlete-Led Enterprises
The launch of Thirty Third Management Group arrives at a pivotal inflection point in the modern sports economy. Over the past decade, the traditional athlete-agent dynamic has undergone a fundamental transformation. Athletes are no longer content with merely collecting a salary and a handful of standard endorsement checks; they are increasingly viewing themselves as venture capitalists, media proprietors, and brand founders.
By establishing Thirty Third Management Group, Jalen Brunson joins a select group of elite athletes who have successfully transitioned from talent to executive ownership. This trend allows athletes to retain a significantly higher percentage of their off-court earnings, build generational wealth, and dictate the terms of their public narratives. Furthermore, by opening the firm’s doors to outside clients—ranging from rising stars in the NIL ecosystem to seasoned corporate executives—Brunson is creating a self-sustaining business model that will outlast his playing days on the basketball court.
Industry analysts suggest that family-run advisory firms offer a distinct competitive advantage in an otherwise crowded marketplace. Where traditional agencies often manage hundreds of clients simultaneously, leading to stretched resources and impersonal communication, boutique family-led firms can offer bespoke, high-touch attention. This individualized approach is particularly attractive to young athletes navigating the complex, high-stakes world of professional sports and digital marketing for the first time.
Looking Ahead: Building a Lasting Legacy in New York and Beyond
As Thirty Third Management Group officially opens its doors in New York City, the firm faces a promising yet demanding road ahead. The challenge will lie in scaling its operations effectively while maintaining the close-knit, family-oriented ethos that defines its core identity. With a clear focus on diversifying client portfolios, championing equity in women’s sports, and providing meticulous brand management, the firm is well-positioned to make a lasting impact.
For Jalen Brunson, Thirty Third Management Group represents the ultimate extension of his basketball IQ into the boardroom. Just as he methodically dissects opposing defenses on the court to orchestrate the New York Knicks’ offense, he is now applying that same strategic foresight to construct a business enterprise designed to endure long after the final buzzer sounds.
