Sean Grove is the Founder of Linzumi, a YC-backed AI platform that serves as the central chat interface for engineering teams to direct and coordinate dozens of AI coding agents.

Sean previously served as an alignment researcher at OpenAI, where he spent years in post-training and alignment reasoning, helping develop model-spec infrastructure and deliberative-alignment techniques.

Sean is a prolific speaker and thinker who argues that specifications, not code, are the true source artifact of software, famously contending that code is only a lossy projection of human intent.

Prior to Linzumi, Sean founded OneGraph, a GraphQL API platform that was acquired by Netlify, where he subsequently served as Principal Architect; he also co-founded Bushido (YC S11) and held roles at PayGarden and Sauce Labs.

Linzumi is backed by Y Combinator, Matrix, SV Angel, Decibel, Pioneer Fund, and Axiom Partners, and enables engineering teams to kick off, review, and ship work entirely from a unified chat interface powered by AI agents.
