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.
