Spence Green is the CEO and co-founder of Lilt, steering an AI-first platform that blends state-of-the-art NLP with professional translation to make the internet truly multilingual. He holds a PhD from the Stanford AI Lab and brings 13+ years of experience translating deep research in machine translation, mixed-initiative systems, and syntax into production products used by enterprises. His background includes research and published work with Stanford, Google (improvements to Google Translate), Johns Hopkins, and technical diligence at XSeed Capital, evidencing a rare mix of academic rigor and commercial judgment. Early software engineering roles at Northrop Grumman gave him hands-on systems and team leadership experience across defense and large-scale web migrations. An active contributor to the Stanford CoreNLP codebase, he combines low-level code improvements with strategic product vision—driven by the mission to make information accessible regardless of language or origin.
