Founders Fund
Founders Fund is a venture capital firm that invests early in ambitious startups, especially in technology, and makes its money when those companies grow or sell.
Founders Fund is a venture capital firm — a place that pools money from wealthy investors and institutions and uses it to buy stakes in young, private companies. The startups it backs are usually trying to build something big and new, often in software, space, defense, health, and other deep technology. Founders Fund puts money in early, sometimes when a company is just a few people with an idea, and then waits years for those companies to grow, raise more money, or sell.
The firm earns its keep through carried interest and management fees. Management fees are a slice of the fund's size paid each year to keep the lights on. Carried interest is the bigger prize: a share of the profits, usually around 20%, when an investment pays off. Its investors — the limited partners — get most of the upside. Founders Fund's reputation rests on being early and being right. It was an early backer of Facebook and SpaceX, and those bets made its name. Founders Fund is known for a specific attitude. Its partners argue that most of the world is underbuilding and that the best companies are the ones trying to make big, ambitious things that sound slightly crazy at first. That has pulled it toward defense, hard tech, and space, areas that many other venture firms avoided for years. It does not just write checks and disappear; it often takes board seats and leans in.
The business is not a sure thing. Venture capital is a hits business: a fund can make many bets and lose on most of them, and the whole return can ride on a handful of winners. Founders Fund closed a large growth fund recently, reflecting that it wants to keep supporting its winners as they get big. Its edge, if it has one, is picking the strange-but-someday-huge companies before everyone else does.

BIG PICTURE
Three venture firms, including Founders Fund, took 48.1% of all VC fund money raised
- 48.1% a16z, Thrive Capital and Founders Fund
- 51.9% All other venture funds
In the first half of 2026, just three firms pulled in 48.1% of all the money raised by venture funds. Founders Fund was one of them, alongside a16z and Thrive Capital. For a firm whose business is spotting and backing startups, that means founders who want its money are dealing with one of the few hands that can write a big check.

Timeline
Thiel Starts Founders Fund
Peter Thiel had already helped build PayPal, and he kept thinking about a problem: the people who start companies often get pushed aside by the investors who fund them. So in 2005 he teamed up with two former PayPal colleagues, Ken Howery and Luke Nosek, and raised a first fund of $50 million. Their promise was simple and a little contrarian: they would back fellow entrepreneurs and never remove a founder from his own company.
The SpaceX Bet
Then came a bet that would define the firm. During the financial crisis, Founders Fund became the first institutional investor in SpaceX, putting in more than $20 million when almost everyone else said no. The company had just suffered three failed rocket launches and was close to running out of money. It looked like a way to lose a lot of money. Instead, that one investment became central to who the firm is and to the returns it would later earn, eventually worth billions.
The Future Manifesto
Over time, the firm grew worried that the tech world had become too focused on social media and apps. So it published a manifesto called "What happened to the future?", arguing that the most ambitious projects, the hard technology that changes the physical world, deserved the attention. From then on, deep tech, defense, and frontier technology became a main focus.
A Miami Office
The firm had long been based in San Francisco, but in 2021 it opened an office in Miami. It was part of a wider movement of venture capital money heading to Florida, and it showed the firm was willing to follow talent and money wherever they went.
Silicon Valley Bank and a Smaller Fund
In 2023, Founders Fund told its portfolio companies to pull their money out of Silicon Valley Bank. The bank failed within two days, and the firm drew attention for its part in the run. That same year, with markets uncertain, it cut its eighth venture fund in half, a sign that even confident investors were being careful.
A $6 Billion Growth Fund
By 2026, the caution had paid off in a big way. Founders Fund closed a $6 billion growth fund, its largest ever, less than a year after spending its previous $4.6 billion fund. That earlier fund had backed just seven companies, with average checks of roughly $600 million, including $1.25 billion in Anthropic and $1 billion in Anduril. The firm had placed billions into frontier AI and defense, putting itself right at the center of the AI money race.
