About
Sam Altman is the CEO of OpenAI, the company behind ChatGPT and GPT-4. Previously, he was president of Y Combinator, one of the world's most successful startup accelerators.

Key Contributions
- Ran Y Combinator during its high-growth era; Tad Friend's 2016 New Yorker profile captured both his ambition and his polarizing style
- Invested across startups and hard-tech bets, including energy, biotech, and identity projects such as Worldcoin
- Co-founded OpenAI around a public-benefit AGI mission, then led its shift toward a capped-profit, product-driven AI company
- Led the 2022 launch of ChatGPT, making conversational LLMs a mainstream interface for work, education, and software
- Built OpenAI's Microsoft partnership and API business, accelerating frontier AI adoption while drawing criticism over closed models and concentrated power
- Became the face of AI governance tensions after his 2023 firing and reinstatement exposed conflict between OpenAI's nonprofit board and commercial momentum

Connections
Ilya Sutskever
CollaboratedCo-founder, Safe Superintelligence Inc.
Both were there at OpenAI's December 2015 launch — Altman as co-chair, Sutskever as the research director who became chief scientist — and they became the two poles of its unresolved question: whether a company can keep building something it believes might be dangerous. In November 2023 Sutskever voted to remove Altman from the board, then within days said publicly that he regretted it; Altman stayed, Sutskever left to found Safe Superintelligence. The rupture remains the most candid thing the industry has said aloud about who governs whom.

Dario Amodei
CollaboratedCEO & Co-founder, Anthropic
Amodei was OpenAI's VP of Research under Altman from 2016 and the last author on the GPT-3 paper, before leaving in 2021 over differences of direction to found the competitor built around the safety case. The relationship has an unresolved coda: in November 2023 OpenAI's board approached Amodei about replacing Altman and merging the two labs, and he declined both. Two men who built the same technology and have never agreed on who should be trusted to steward it.

Demis Hassabis
In contrastCEO, Google DeepMind
An instructive opposition rather than a feud: DeepMind's founding order was solve intelligence, then use it to solve everything else — games, protein folding, weather — while OpenAI arrived at general intelligence by putting a chat box in front of the public and letting a hundred million people find its edges. One route earns a Nobel Prize in chemistry; the other rewrites how people work within a season. In 2023 both signed the same one-sentence statement placing extinction risk beside pandemics and nuclear war.
