SaaStr Fund specializes in investing in 4-5 B2B startups annually, with annual recurring revenues (ARR) between $0.1m and $2m. They prefer to lead funding rounds with initial investments ranging from $500k to $4m and are comfortable being the sole investor. The fund targets founders from diverse and non-traditional backgrounds, aiming for a high success rate with fewer, concentrated bets. They prioritize B2B, B2D, and AI companies with at least 10 unaffiliated customers and $10k in monthly recurring revenue (MRR), and they support their investments by helping build management teams, promoting the company, and securing future funding rounds. SaaStr Fund values integrity, persistence, and involvement in the SaaStr community, and they welcome cold emails as a means of introduction.
