Summary
🤩
Rockstar🎓
Top SchoolSteve Johnson is a technology executive, operator and investor with 11 years of hands-on engineering and venture experience, now co-founding Seguin Ventures to back AI-native software at pre-seed through Series A. He combines an MBA from Kellogg with a technical contributor mindset—his GitHub history includes back-end work on a Rust gRPC implementation, showing continued low-level systems fluency. Based in Harpswell, Maine, he advises robotics, security and AI startups (GrayMatter Robotics, Lift AI, Defendify) and serves as a venture partner at F-Prime, blending deal instincts with product and engineering judgment. Steve’s background spans influential tech companies (Buoyant, Twitter, Google) and operational investing in companies like Kick.co and Topicflow, giving him a rare perspective across developer tools, cloud-native systems and go-to-market. He’s equally comfortable discussing API surface design and cap table dynamics, and brings a pragmatic, builder-first approach to supporting founders.
