Refactor
the world.
Are you a hard tech founder? Better Call Zal.
I’m Zal (like “Saul”), founding partner at Refactor. I invest in seed-stage hard tech companies primarily in the US. What does “refactor” mean? In computer science, refactoring code improves its efficiency and scalability. Here, our companies aim to refactor their respective industries, whether it’s bio, climate, energy, aerospace, etc.
I typically lead or co-lead pre-seed and seed rounds with $1-2M checks from my 4th fund ($50M in size), which I started to deploy in July 2024. As a solo capitalist and the only decision maker at Refactor, I make decisions fast, and if we team up, you’ll have me on speed dial whenever you need me. It’s that simple. #BetterCallZal

Capital is personal.
Starting a company can be a lonely journey. I understand that more than others as I am a solo capitalist. I will make your vision and journey my primary focus. Expect highly responsive, one-on-one attention from me, along with the guidance and experience of our trusted team of advisors.
