Mark Cuban started his first company with $500 from his first customer.
He had just been fired from a software store in Dallas and was sleeping on the floor of a three-bedroom apartment he shared with five friends. He told the customer that if the software didn’t work, he would wash their car.
What came after:
MicroSolutions, sold to CompuServe in 1990
Broadcast.com, sold to Yahoo for $5.7B in 1999, with Cuban still owning a third
The Dallas Mavericks, bought for $285M in 2000
Cost Plus Drugs, launched in 2022 with 111 medications
What would he build today? We asked him in Las Vegas last October. His answer was AI, repeated six times.
Since then he has given founders the same playbook in every interview: learn agents, walk into small businesses and charge for the work they never get to.
📚 In this newsletter, we break down the seven rules he has followed since his first $500 and the AI playbook he gives founders today with clips.
Inside you will find:
Get Paid by Customers Before You Raise From Investors See why Cuban treats cash as more important than revenue and raising money as an obligation.
Know Your Business Better Than Anyone Trying to Kill It The learning habit he built reading software manuals at night, and still runs today with agents.
Bet on the Ideas People Call Stupid Learn how to tell a contrarian bet from a bad idea, and why you only have to be right once.
Sell Trust and Let Your Customers Do the Marketing The trust formula behind Cost Plus Drugs, and the cookie company making $12M in profit with zero ads.
Hire People Who Cover Your Weaknesses His startup rules on teams, the day his partner told him he was a jerk, and why star hires rarely save a company.
Use AI to Show Up With the Work Already Done Build the 12-minute business plan and the weekly price report, and pass the test he now runs on every founder.
Start Where Small Businesses Need AI Most The $100-an-hour agent business he would start at 20, and the Rebel Cheese agent that recovers $50K a month.
