Costanoa Ventures is a Palo Alto–based firm in the venture space that supports startups from formation through early growth stages in sectors including Applied AI, AI infrastructure, cybersecurity, national security, and fintech. The firm pursues a boutique approach, intentionally maintaining a smaller footprint to provide deeper expertise and hands-on operational support during the early growth phase. It targets founders pursuing companies with significant impact, acting as a specialized partner within its technology-focused ecosystem.

In early 2026, Costanoa sponsored the MIT-Harvard Technology and National Security Conference Innovation Showcase, demonstrating engagement with the wider tech and security community. Based in Palo Alto, the firm emphasizes focused collaboration and tailored guidance for early-stage companies rather than broad, generic support.
