Call Zal.
Refactor invests in hard tech founders.
I’m Zal (like “Saul,” but with a Z), founding partner of Refactor. I invest in seed-stage hard tech companies, primarily in the US.
In computer science, refactoring improves code efficiency and scalability. At Refactor, I back founders refactoring the real world—including aerospace, energy, biology, and physical AI.
I lead or co-lead pre-seed and seed rounds with $1–2M checks from my 4th fund ($50M), which I began deploying in July 2024. Refactor is intentionally a solo capitalist firm: one investor, fast decisions, and direct access to the person writing the check.
If we work together, you’ll have me on speed dial. #BetterCallZal
