About Jerry Tworek
Jerry Tworek is a Polish AI researcher based in San Francisco. He is co-founder and CEO of Core Automation, an AI research lab he started in 2026. Crunchbase lists his previous role as VP of Research at OpenAI.
He left OpenAI in January 2026 after about seven years. At OpenAI he worked on reasoning models, reinforcement learning, Codex and earlier GPT models. His X profile lists o1, o3, GPT-4, ChatGPT, Codex and RL for robots. One secondary profile says he studied mathematics at the University of Warsaw and worked in quantitative finance before OpenAI. That profile is not a primary source.
Core Automation says it wants to build the most automated AI lab in the world. It is developing new learning algorithms and architectures intended to scale better than transformers. Press reports in 2026 say Nvidia is among its early backers and that the company was seeking more funding at a valuation reported at around $4 billion.
Tworek's only publicly documented angel investment is Sycamore. Crunchbase shows one personal investment, in Sycamore's seed round, and lists one portfolio company. Sycamore's March 30, 2026 press release names him among the angel investors in the round, describing him as a former Research Scientist at OpenAI.
We found no public record of other angel investments, a fund, or a stated investing program. We found no public statements from him about what he looks for in startups or his typical check size.
Sycamore Labs is a Palo Alto startup led by former Atlassian CTO Sri Viswanath. It is building an agentic operating system for enterprises, covering the discovery, building, deployment and oversight of AI agents, with security and governance controls. It announced a $65M seed round on March 30, 2026, led by Coatue and Lightspeed Venture Partners. Abstract Ventures, Dell Technologies Capital, 8VC, Fellows Fund and E14 Fund also took part, along with a group of angels. The amount Tworek invested has not been disclosed.
With one known investment, there is not enough public information to describe a stage or geographic focus. That investment was an enterprise AI infrastructure company at seed stage, and Tworek's own work is in frontier AI research. His check size is not public. Founders should treat any claim about his preferences as unconfirmed unless he states it himself.
