He later enrolled for a computer science course at Stanford University. However, he dropped out in 2005.
Career Beginnings
Sam Altman co-founded Loopt shortly after dropping out of Stanford University. Loopt was a company that provided geo-social networking mobile application services which allowed smartphone users to share their physical locations selectively.
In addition to founding Loopt, Altman also served as its CEO. However, the company shut down in 2012 despite its founders raising over $30 million in venture capital. It was later acquired by Green Dot Corporation
Career Breakthroughs
Sam Altman joined the technology startup accelerator Y Combinator in 2011 as a part-time partner. This turned out to be one of the best investment decisions of his life. Y Combinator has helped launch over 3,000 startups over the years. Noteworthy ones include Airbnb, Reddit, Twitch, and DoorDash.
Altman rose through the ranks to become Y Combinator’s president in 2014, taking over from Paul Graham. He instituted a new deal for startups, in which Y Combinator provided $150,000 funding in exchange for 7% equity.
In 2015, Sam Altman announced the establishment of a $700 million growth-stage equity fund called YC Continuity. The fund invested exclusively in Y Combinator companies. The same year, Altman founded a non-profit research laboratory known as Y Combinator Research. The lab’s focus areas included education, urban development, basic income, and the future of computing.
In 2016, Sam Altman became the president of YC Group, a collective of Y Combinator and its other distinct units.
In 2019, Altman transitioned to the role of YC Group chairman so he could get ample time to focus on his other fledgling company – OpenAI. He was replaced as CEO by Geoff Ralston the same year before eventually leaving the company.
Sam Altman’s OpenAI was created in December 2015 in collaboration with many other investors, including Elon Musk. However, Altman did not focus on the company until he quit working for Y Combinator.
OpenAI comprises the for-profit OpenAI LP as well as the non-profit OpenAI Inc. Based in the Mission District of San Francisco, the company conducts research in the field of artificial intelligence. Altman is its current CEO.
One of OpenAI’s most popular products is the GPT-3 language model that automatically generates human-like speech while also offering translation services. Others include Gym – a public beta version of its reinforcement learning research platform, as well as Universe – a software platform for gauging AI’s capabilities across millions of websites, applications, and games.
Other Ventures
In 2019, Sam Altman co-founded Tools For Humanity, a company that uses a cryptocurrency known as Worldcoin to build a global iris-based biometric system.

Sam Altman’s Net Worth

Sam Altman is a shrewd entrepreneur and investor with a net worth of $500 million as at September 1, 2023. He has earned his millions through his involvement in numerous successful projects, such as OpenAI and Y Combinator.
Altman would have become a billionaire in January 2023 after a deal between OpenAI and Microsoft led to a private funding round that valued the AI company at $29 billion. However, it later emerged that Sam had not taken any equity in OpenAI. So, he definitely missed out from the company’s cash windfall.
That said, Sam Altman seems to be on course to join the billionaires club. That’s especially when you consider that OpenAI’s ChatGPT currently has over 100 million users.
While ChatGPT is mostly free for basic usage, there’s a premium version that costs $20/month and provides more generative features. Besides, the chatbot’s framing as a “preview” implies that the developers are probably considering introducing an exclusive premium plan.
Private Life
Sam Altman is gay. He’s presently in a relationship with Australian software engineer Oliver Mulherin.
Prior to meeting Mulherin, Altman was in a 9-year relationship with Loopt co-founder Nick Sivo. The couple broke up when the company was purchased in 2012.
