Mark Cuban

General Partner, President

Mark Cuban is a pioneering entrepreneur, investor, and sports team owner, currently serving as a General Partner at Harbinger Sports Partners Fund I, LP,  where he brings decades of innovation and success at the intersection of sports, media, and technology. Known for his bold vision and disruptive approach, Cuban plays a pivotal role in shaping investment strategies that target high-growth opportunities in the global sports ecosystem.


Entrepreneurship & Corporate Leadership

Cuban rose to prominence during the tech boom of the late 1990s, co-founding Broadcast.com and later selling it to Yahoo! for $5.7 billion. Since then, he has built a dynamic career investing in and advising companies across industries ranging from AI and healthcare to fintech and entertainment.


As owner of the NBA’s Dallas Mavericks since 2000, Cuban transformed the franchise into a perennial contender, delivering an NBA championship in 2011 and dramatically enhancing the fan experience through innovation and community engagement. The Mavericks have become a model for digital strategy and player-first culture under his ownership.


Cuban is also a cornerstone investor on the Emmy Award-winning show Shark Tank, where he’s helped scale dozens of early-stage companies with a hands-on, entrepreneur-first approach. In 2022, he founded Cost Plus Drugs, a public-benefit corporation committed to radically improving transparency and affordability in the U.S. pharmaceutical industry.


Philanthropy & Civic Engagement

A passionate advocate for access, equity, and innovation, Cuban has supported numerous causes, particularly in healthcare, education, and entrepreneurship. His philanthropic efforts include funding initiatives that bridge digital divides, provide medical access, and create economic mobility for underserved communities.


Personal Life

Cuban holds a business degree from Indiana University’s Kelley School of Business. He and his wife Tiffany are proud parents of three children and are actively involved in philanthropic and community-focused efforts in Dallas and beyond.
