About Mark Cuban
Mark Cuban was born in Pittsburgh and graduated from Indiana University Bloomington with a business degree. His first company was MicroSolutions, a software and computer services firm that he sold for $2 million, according to EBSCO.
In 1995 he founded the video portal Broadcast.com (originally AudioNet) with Todd Wagner. According to Forbes, they sold it to Yahoo for $5.7 billion in 1999. He later founded the HDNet and AXS TV channels and co-founded 2929 Entertainment.
He sold 58% of the Dallas Mavericks in December 2023 and keeps a minority stake, per Forbes. In January 2022 he launched Mark Cuban Cost Plus Drugs, which aims to lower prescription drug prices. He was an investor on ABC's Shark Tank for 13 seasons and announced his exit from the show in 2025. His company directory is at markcubancompanies.com.
Cuban invests mainly his own money. Crunchbase lists 44 investments for him. Other trackers count more: Dealroom shows 252 investments and Tracxn shows 125 portfolio companies. The counts differ because each tracker covers different deals, so treat any single figure as approximate.
On Shark Tank he invested in 85 companies, according to GOBankingRates. He told CNBC in 2025 that he put about $33 million into the show's deals and estimates the remaining stakes are worth at least $250 million. One early Shark Tank deal was $150,000 in Tower Paddle Boards in 2011.
Outside the show, his backing includes Percepto, the drone computer vision company he has held since 2015, per Yahoo Finance. Other backed companies in trackers include Upstart, Sportradar, Dave and Underdog Fantasy. Tracxn lists 24 portfolio exits, including Dave, Sportradar, Cadre and FiscalNote. Crunchbase shows no exits for him, so the sources disagree.
Crunchbase counts 11 AI investments since 2023. Its AI portfolio list includes Bot-It, BoldHue, Clipbook, DIRT Research Technologies, Leverage, ESAI, Yendo, Advanced Machine Intelligence and ASI.
Clipbook, an AI media monitoring platform, announced a $3 million seed round on December 1, 2025, co-led by Cuban, Commonweal Ventures and Carpenter Capital. Its founder, Adam Joseph, reached Cuban by cold email in late 2024. In October 2025 Yendo, a Dallas AI credit platform, announced a $50 million Series B that included Cuban. In December 2025 he joined a $4 million Series A extension for Orreco, an AI sports performance company.
Tracxn and Seedtable list a seed round for AMI Labs in March 2026, with a round size of about $1 billion. Cuban was among its investors. He is also a returning investor in FORT Robotics, which makes safety hardware and software for autonomous machines. Bloomberg reported that the company plans to go public through a SPAC merger at an enterprise value of about $557 million.
Cuban's disclosed deals run from pre-seed to Series B. Trackers show him mostly in early rounds, sometimes alongside larger venture funds. Sectors include AI and machine learning, fintech, robotics, security, enterprise software, media, sports technology and consumer products. Dealroom shows most of his portfolio in the United States, with smaller numbers in Canada, the UK, Australia and elsewhere.
He has said he reads his own inbox. He told TechCrunch he has invested tens of millions of dollars from emails, and Clipbook is an example. According to the reporting on that deal, he opened with skeptical questions to test the founder's grasp of the business. He tends to favor products where he knows the problem well. On Clipbook he said he knows how painful PR and marketing research is.
On risk, he told CNBC that a $10,000 check carries a different risk and reward profile than a $1 million check. He also looks at a founder's effort, intelligence and ability to sell. He has not published a standard check size. Third-party databases give ranges, but we could not confirm them, so none is stated here.
