Ben: What was your path into venture?
Riley: I started in investment banking with early exposure to high-growth tech companies, then moved into private equity, focusing on software. Transitioning to seed-stage VC was a mindset shift, but the foundational skills—diligence, evaluating teams, understanding go-to-market—have all carried over.
Ben: What pulled you into deep tech and defense tech?
Riley: It wasn’t planned, but the interest grew naturally. Defense tech is a meaningful part of what we do, and I’ve been fortunate to learn from teammates with deep experience in that world – veterans and technologists alike. It’s a complex space, but incredibly rewarding and relevant.
Ben: Can you provide a high-level walk through of Harpoon’s investment thesis?
Riley: We invest across AI, cybersecurity, software infrastructure, and deep tech. That includes everything from next-gen connectivity to autonomous systems to novel energy and manufacturing solutions. We keep a broad mandate, with a team that brings a mix of finance, national security, and early to late-stage investing experience.
Ben: What do you look for in deep tech founders?
Riley: We’re looking for relentless, mission-driven builders—the kind of founders who’d go down with the ship or take it to orbit. Many have experience solving hard problems inside top-tier technical environments. They’re focused, resourceful, and often tackling niche challenges that unlock massive opportunities.
Ben: How does Harpoon support portfolio companies’ post-investment?
Riley: We’re hands-on where it matters—government contracting, regulatory strategy, dual-use positioning. Our team and network help founders navigate what can otherwise be a daunting space. We act as a force multiplier, especially when it comes to connecting commercial ambition with national interest.
Ben: What emerging trends are you most excited about?
Riley: In defense, we’re seeing massive shifts—tactical autonomy, next-gen threat detection, and new procurement pathways. In broader deep tech, it’s the resurgence of American manufacturing, energy innovation, and the infrastructure behind AI. Regulatory and cultural tailwinds are accelerating the space.
Ben: Any advice for students breaking into VC or deep tech?
Riley: There’s no single path. Share your thinking publicly, build a network, and find ways to add value. Whether through technical experience or operational chops, showing curiosity and conviction goes a long way. This space rewards builders—at every level.
