AI's Linux moment
Oumi emerged from stealth in January 2025 with $10M in seed funding led by Venrock and Obvious Ventures. Founded by ex-Google Cloud AI leader Manos Koukoumidis (CEO) and ex-Apple engineer Oussama Elachqar, the Seattle-based public benefit corporation was built with 20+ researchers from Google, Apple, Meta and Microsoft alongside collaborators from 13+ universities including MIT and Stanford.
One platform for the model lifecycle
The open-source Oumi platform (9,000+ GitHub stars) handles everything needed to build custom models: data synthesis and curation, fine-tuning and pretraining from 10M to 405B parameters, evaluation, and deployment — with full reproducibility of code, data and recipes rather than just open weights. The commercial layer promises custom models from a simple prompt in as little as two hours, claiming up to 50% higher accuracy than frontier models on targeted tasks and up to 90% lower costs, with customers owning their weights outright.
Open by charter
As a PBC, Oumi commits to keeping its core platform 'unconditionally open' — no license switches or gated features — positioning it as neutral infrastructure the research community can standardize on.
