## About B5 Capital

B5 Capital is a family seed fund investing in technology startups, positioning itself as a high impact, low maintenance investor. The firm believes great companies are built on great products and that founder-led companies are the primary engine of innovation in the economy. It is a single-family office founded in 2018 and based in San Francisco/Silicon Valley, California.

B5 Capital invests in Pre-Seed, Seed and Series A technology companies, focusing on SaaS, Cybersecurity, AI (infrastructure and vertical apps), Fintech, ClimateTech, and SpaceTech. It backs global companies that may start anywhere but aspire to operate worldwide. It does not invest in life-science companies.

The firm's portfolio includes notable exits such as Noname Security (acquired by Akamai), Axis Security (acquired by HP), and Trustdome (acquired by Zscaler), alongside active investments like NeoAgent, reflecting a strong track record in cybersecurity and AI-driven infrastructure.

B5 Capital's investment approach emphasizes practical, founder-first support paired with patient family capital, prioritizing entrepreneurs who demonstrate strong product execution and market conviction over extensive board control or heavy operational oversight.
