Who we are
5Side Capital is an early-stage venture firm investing in breakthrough dual-use and national security technologies. We back founders developing commercially scalable solutions with strategic defense applications, focusing on opportunities from Pre-Seed through Series A. As architects of today’s defense innovation ecosystem, our team helped shape the frameworks and organizations that connect emerging technology with national security needs. We now leverage that experience to not only invest in transformative companies but also to help them navigate the complexities of working with the U.S. government. By bridging the gap between the Valley and the Beltway, we accelerate technologies that strengthen U.S. competitiveness, resilience, and security.
