Stefano Ermon co-founded Inception, an AI research and product company developing diffusion-based language models, where he serves as CEO. Inception's founding team also includes Aditya Grover and Volodymyr Kuleshov. Under Stefano Ermon's leadership, Inception announced the Mercury family of diffusion large language models, available through a playground, API, and on-premise deployments. Inception raised $50 million in funding led by Menlo Ventures, with participation from Mayfield, Innovation Endeavors, NVentures, M12, Snowflake Ventures, and Databricks Investment. Stefano Ermon also co-founded Atlas AI, where he serves as Chief Technical Advisor.

Stefano Ermon's research contributions span several influential works in generative AI. He co-authored Denoising Diffusion Implicit Models (DDIM) with Jiaming Song and Chenlin Meng, co-authored FlashAttention with Tri Dao and collaborators, and co-authored Generative Adversarial Imitation Learning (GAIL) with Jonathan Ho. His work on score-based generative modeling through stochastic differential equations helped establish a unified framework connecting score-based and diffusion probabilistic modeling.
