SaaStr Fund is a venture capital firm that invests $750k‑$5m in early‑stage AI‑driven B2B software companies, typically at the seed or late‑seed stage with $0.1‑$2m ARR. The fund makes a handful of concentrated bets each year, leads or co‑leads rounds, and provides mentorship, go‑to‑market support, and access to the broader SaaStr ecosystem. It backs founders worldwide but prefers those who can engage with the Bay Area regularly.
