Jay Hack

I'm the Head of AI at ClickUp, where I lead our work on agents for general-purpose knowledge work.

I founded Codegen, a coding agent backed by Thrive that grew to serve Ramp, Notion, Ironclad and many more. Codegen was acquired by ClickUp in 2025.

I also built AI-driven shopping at Mira AI Inc, intelligent data systems at Palantir, and studied CS/AI at Stanford.

This is my actual name and not a pseudonym.
