Mu Li

Mu Li is the co-founder of BosonAI, an LLM startup he launched after serving as a principal scientist at Amazon, where he spent roughly seven and a half years before leaving to start the company in 2023 . In a first-person account published in mid-2024, he described the founding process as deliberately defiant — assembling a team with leads across data, pre-training, post-training, and architecture, then navigating a volatile fundraising environment where a lead investor pulled out at the last minute . He has framed his move into entrepreneurship as a response to a long-held impulse, writing that "if there's something you're meant to try in life, start as early as possible" .
