Founders Fund: the contrarian powerhouse behind SpaceX, Palantir and Anduril

Founders Fund is one of the most recognisable names in venture capital — the San Francisco firm behind SpaceX, Palantir and Facebook. Founded in 2005 by PayPal co-founder Peter Thiel with Ken Howery and Luke Nosek, it has grown to roughly $17 billion in assets under management. Its defining instinct is contrarian: back ambitious founders building revolutionary technologies, and hold the line when the market disagrees.

Investment thesis

The firm invests in smart people solving difficult problems, across all stages, sectors and geographies. Its philosophy was laid out in Bruce Gibney's 2017 manifesto, "What happened to the future?", built around Thiel's famous line: "We wanted flying cars, instead we got 140 characters." It has pivoted from consumer internet to become one of Silicon Valley's heaviest backers of hard tech, defence and frontier AI.

Sectors & stages

Founders Fund is deliberately industry-agnostic and multi-stage, from seed to late-stage growth. Its sweet spot today is aerospace, defence tech, artificial intelligence, fintech, biotech and space. The portfolio spans SpaceX, Palantir, Stripe, Airbnb, Anduril, DeepMind, Spotify, Neuralink, Nubank, Ramp, Flexport, OpenAI.

Fund & cheque sizes

With about $17 billion in AUM as of 2025, the firm runs parallel venture and growth franchises. Landmark raises include a combined $3 billion in 2020 and the $4.6 billion Founders Fund Growth III in 2025 — the largest raise in its history. Notably, Thiel halved the eighth venture fund from around $1.8 billion to about $900 million in 2023, arguing that "venture capital is due for a slimdown". Cheque sizes are not published as a range, but the third growth fund targets roughly $460 million per company across about ten portfolio names.

Notable portfolio

The firm's $1 billion investment in Anduril's 2025 Series G is the largest single investment in its history. It was the first institutional investor in SpaceX and Palantir, an early investor in Facebook, and has backed Stripe, Airbnb, DeepMind, Nubank, Neuralink. Partners have also incubated companies in-house, including Anduril and Varda Space Industries.

Partners & team

Peter Thiel remains the firm's lodestar. Trae Stephens co-founded Anduril. Mike Solana, Lauren Gross (partner and COO), Scott Nolan, Napoleon Ta and Delian Asparouhov round out the partnership. The firm operates from the Letterman Digital Arts Center in San Francisco, with a Miami office opened in 2021.

Programs run

Founders Fund runs no public accelerator. Its signature gathering is the invite-only Hereticon conference — billed as "a conference for thoughtcrime" — which celebrates technologies ambitious enough to transform the world. For founders, the signal is simpler: the firm prefers direct, conviction-led relationships over programme pipelines.

How to approach

Founders Fund invests across all stages and geographies and publishes no India-specific programme, so founders typically engage the San Francisco team directly, usually through a warm introduction from a portfolio founder or a co-investor. The bar is high and deliberately contrarian: the firm funds people it trusts to build things that should not be possible. If your startup is an incremental SaaS tool, look elsewhere; if it is a rocket, a drone swarm or a new financial primitive, you have its attention.
