Two calls made by hand, not formulas. how we score →
Summary
He started in his parents' house in a well-off Maryland suburb, with a father's PC and a bedroom, and charged for a shareware game by mail.
The cost of failing was low: he was a student living at home. What he kept was control. Epic took outside money late, and he is still reported as the largest shareholder.
Where they worked
How it happened
Sweeney grew up in Potomac, Maryland, the youngest of three brothers. His father worked for the Defense Mapping Agency and gave him an IBM PC/AT. He had a Commodore 64 and an Apple II before that, and has estimated he spent more than 10,000 hours teaching himself to program between eleven and fifteen, mostly through bulletin boards. As a teenager he mowed lawns for wealthy neighbors, at half the going rate.
While studying mechanical engineering at the University of Maryland he set up a consulting firm, Potomac Computer Systems, run from his parents' home. It didn't take off. Wikipedia describes it as shelved, and no start-up capital for it is documented.
He wrote ZZT in a Pascal text editor and released it on January 15, 1991, as shareware: the first episode free, further worlds by mail order, with orders going to his parents' address. Sales started at a few copies a day and had reached about $100 a day by November 1991. That was enough to persuade him to make games for a living, and he renamed the company Epic MegaGames. Because the product sold itself through bulletin boards, he never needed an investor or a publisher to get started.
Mark Rein joined as vice president in 1992. The company moved to Cary, North Carolina in 1999, became Epic Games, and released Unreal in 1998. The engine behind it, Unreal Engine, became the company's licensing business, and Epic's own games, including the Gears of War series, ran on it. Sweeney left college one credit short of his degree because the company was taking his time.
In 2012 Tencent bought a stake in Epic that Wikipedia puts at about 48.4% of outstanding stock, or 40% of the company including employee options, for $330 million. Tencent can nominate board directors. Sweeney is described as the controlling shareholder; Wikipedia's infobox lists him at 41.4%, though the article gives no voting figure.
Fortnite launched in paid early access in July 2017, then as a free battle royale in September 2017, and was estimated to have passed $1 billion in revenue by July 2018. Epic then took on the app stores. After Epic added its own payment system to Fortnite in 2020, Apple removed the game and Epic sued. In 2021 a judge ruled largely for Apple, but against it on anti-steering rules. A jury found against Google in a separate case in December 2023. Epic itself also paid in the FTC matter, reported at $520 million in December 2022 across privacy and purchase-practice claims. These are company-level matters, not findings about Sweeney personally.

The cost-of-failure score comes from this person's own money and circumstances. But who they were in America carried its own weight, the same way their household or income did, and it shaped how hard the path was just as much. That part isn't in the cost-of-failure number. It's here instead.
Men founded the companies that took nearly all the venture funding and almost every top outcome, a tailwind that never shows up in one person's own circumstances.
↗ techcrunch.comWhite founders are heavily overrepresented among funded companies and top-tier wealth relative to their share of the population, an edge that has nothing to do with a person's own money.

Each holds one thing constant and varies another, so the difference is the point. A list of similar names wouldn't tell you anything.
