Jay Hack

I'm a mathemagician. I like building mind-blowing products with AI that seem like magic. What an incredible time to be alive.

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

Previously, 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.

Before that, I 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.
