OpenAI announced OpenAI Grove in September 2025, a mentorship program targeting technical talent at the earliest stages of company building. Unlike traditional accelerators that require established startups, Grove accepts individuals without concrete business ideas who want to explore AI entrepreneurship. The first cohort of approximately 15 participants completed the five-week program between October and November 2025 at OpenAI’s San Francisco headquarters.
What Makes Grove Different
OpenAI Grove is not a conventional startup accelerator. The program specifically targets “pre-idea” individuals who are curious about building AI companies but haven’t yet formed a concrete startup concept.
Traditional programs like Y Combinator or OpenAI’s own Pioneers program require established companies with products. Grove operates at an earlier stage, offering mentorship before entrepreneurs have defined their direction.
Key features include:
- Direct collaboration with OpenAI researchers and technical leaders
- Early access to unreleased OpenAI tools and models
- Weekly office hours and in-person workshops
- No requirement to use OpenAI’s API or technology stack
Program Structure and Requirements
The five-week program required two in-person weeks in San Francisco, the first and last with OpenAI covering travel costs. Middle weeks operated asynchronously, requiring 4–6 hours of weekly commitment.
Participants received technical mentorship, joined a curated peer network, and gained hands-on experience with pre-release OpenAI models. After completion, founders could pursue raising capital, explore roles within OpenAI, or continue building independently.
The program welcomed individuals from all backgrounds and experience levels, including teams applying together. Applications closed on September 24, 2025, with the inaugural cohort running October 20 through November 21, 2025.
Why OpenAI Built Grove
OpenAI designed Grove to connect with potential talent and ideas earlier in the startup ecosystem. The program addresses a gap where early-stage founders have the least resources but often need the most support.
By engaging entrepreneurs before they commit to specific directions, OpenAI can help shape market-oriented AI applications while building long-term relationships with emerging founders. Participants who succeed may eventually join OpenAI’s established programs like Pioneers or OpenAI for Startups, which support later-stage companies.
The program also serves as a talent pipeline, offering pathways for participants to explore internal opportunities at OpenAI alongside external entrepreneurship.
What Happens Next
OpenAI has not announced future Grove cohorts or application timelines as of January 2026. The inaugural cohort completed their program in late November 2025, with participants now in post-program stages exploring funding or other development paths.
The program established itself as OpenAI’s earliest-stage founder initiative, distinct from their existing startup support programs. Future cohorts would likely follow a similar structure if the program continues.
