Summary
👤
Senior🎓
Top SchoolSoichi Sumi is a technology leader and CEO with eight years of hands-on software engineering and platform leadership experience, most recently founding and helming LeapInsight after leading platform efforts at Ginco. He built his career on server-side systems, blockchain infrastructure, and authentication services, progressing from founding engineer to Head of Platform and Senior Engineer roles. Based in Chiyoda, Japan, he combines product-minded engineering with startup grit—launching infrastructure and development guidelines for multi-product “Air” series work earlier in his career. A master’s graduate in computer science from Osaka University, he also publishes technical writing and talks (soichisumi.net, SpeakerDeck) that reflect a practitioner’s focus on doing what’s right. Less obvious: alongside executive duties he has maintained self-employed consulting stints, signaling a continual appetite for hands-on technical problem solving even while leading organizations.
