# Founders Fund Founders Fund is a San Francisco-based venture capital firm founded by Peter Thiel, known for early investments in technology companies including OpenAI and Anduril Industries. Founders Fund is a venture capital firm headquartered in San Francisco, California. It was founded in 2005 by Peter Thiel, along with Ken Howery, Luke Nosek, and [Elon Musk](https://www.wikiprompt.org/wiki/elon-musk). The firm invests across a range of sectors, including software, artificial intelligence, aerospace, and biotechnology. Founders Fund is known for its contrarian investment philosophy and its focus on backing ambitious founders working on transformative technologies. The firm has backed several notable companies in the [artificial intelligence](https://www.wikiprompt.org/wiki/artificial-intelligence) space. In 2015, Founders Fund participated in the founding investment of [OpenAI](https://www.wikiprompt.org/wiki/openai), the research organization dedicated to ensuring that artificial general intelligence benefits all of humanity. The firm also invested in Anduril Industries, a defense technology company that applies AI to national security challenges. These investments reflect Founders Fund's interest in frontier technologies with the potential for significant societal impact. ## Investment Philosophy Founders Fund is characterized by a thesis that emphasizes backing founders who pursue "moonshot" ideas - projects that may seem risky or unconventional but have the potential to create entirely new markets. The firm's partners often describe their approach as focusing on companies that can achieve outsized returns, rather than incremental improvements. This philosophy has led to investments in areas such as space exploration, advanced materials, and [machine learning](https://www.wikiprompt.org/wiki/machine-learning). The firm's early backing of [OpenAI](https://www.wikiprompt.org/wiki/openai) was notable because, at the time, large-scale [deep learning](https://www.wikiprompt.org/wiki/deep-learning) research was not a typical focus for venture capital. Founders Fund's willingness to support such research helped catalyze later investment in the field. ## Notable Investments Beyond OpenAI and Anduril, Founders Fund has invested in a wide array of technology companies. In the [large language model](https://www.wikiprompt.org/wiki/large-language-model) space, the firm has backed companies such as [Inflection AI](https://www.wikiprompt.org/wiki/inflection-ai), which develops conversational AI systems. It has also invested in [Figure AI](https://www.wikiprompt.org/wiki/figure-ai), a company building humanoid robots, and [Sanctuary AI](https://www.wikiprompt.org/wiki/sanctuary-ai), another robotics firm focused on general-purpose robots. In the autonomous vehicle sector, Founders Fund was an early investor in [Cruise](https://www.wikiprompt.org/wiki/cruise), the self-driving car company, and [Waymo](https://www.wikiprompt.org/wiki/waymo), which originated from Google's self-driving car project. The firm also invested in [Neuralink](https://www.wikiprompt.org/wiki/neuralink), a company developing brain-computer interfaces, reflecting its interest in neurotechnology. ## Team and Leadership Peter Thiel, co-founder of PayPal and Palantir, serves as a partner at Founders Fund. Other partners include Brian Singerman, Keith Rabois, and John Langelier. The team includes investors with backgrounds in engineering, finance, and entrepreneurship, allowing the firm to provide operational and strategic support to portfolio companies. Founders Fund has offices in San Francisco and New York. The firm manages multiple funds, with assets under management exceeding $11 billion as of 2024. ## Impact on AI Ecosystem Founders Fund's investments have had a significant impact on the [AI](https://www.wikiprompt.org/wiki/artificial-intelligence) ecosystem. By funding early-stage AI research and applications, the firm has helped accelerate the development of [generative AI](https://www.wikiprompt.org/wiki/generative-ai) technologies. Its support for [OpenAI](https://www.wikiprompt.org/wiki/openai) contributed to the creation of models like [GPT-3](https://www.wikiprompt.org/wiki/gpt-3) and [GPT-4](https://www.wikiprompt.org/wiki/gpt-4), which have become foundational in the field of [large language models](https://www.wikiprompt.org/wiki/large-language-model). The firm's involvement in defense technology through Anduril has also influenced the application of AI in national security, a domain that has grown in importance. ## Criticism and Controversy Founders Fund has faced criticism for its investments in companies that raise ethical concerns, such as [Neuralink](https://www.wikiprompt.org/wiki/neuralink) and defense contractors. Some critics argue that the firm's focus on high-risk, high-reward ventures can lead to unintended consequences. However, the firm maintains that its investments are driven by a belief in technological progress and the potential for positive impact. ## See Also - [OpenAI](https://www.wikiprompt.org/wiki/openai) - Anduril Industries - Peter Thiel - Venture capital --- Source: https://www.wikiprompt.org/wiki/founders-fund License: CC BY-SA 4.0 (https://creativecommons.org/licenses/by-sa/4.0/) Last updated: 2026-09-05T14:07:45.150176+00:00
