Risking It All?

Better Call Zal.


I’m Zal (rhymes with “Saul”), solo capitalist at Refactor. For over a decade, I’ve backed founders refactoring the real world.

I invest $1–2M in seed stage hard tech startups across the US. Refactor is a solo employee firm managing $300M across five funds. If we work together, I want to be your first call.

A Refactor founder coined “Better Call Zal.”

I try to earn it every day.
