Summary
🤩
Rockstar🎓
Top SchoolDarren Baldwin is a founder-first CTO and engineer with five years of startup experience building developer tools, applied AI products, and open-source software. As co-founder and CTO at Tembo and earlier Rezon.ai, he has led technical pivots, helped raise venture capital, and launched early user waitlists, combining hands-on engineering with product and fundraising experience. He co-created Cincinnati Ventures to scale open-core data and infrastructure products, and maintains an active OSS presence and freelance work on GitHub. Based in Cincinnati, he favors pragmatic, developer-focused tooling and has repeatedly moved ideas from MVP to funded ventures, often working closely with research-caliber engineering talent. An interesting detail: he has a pattern of founding multiple companies that iterate rapidly—shifting roles from founding engineer to CTO while keeping code-level involvement.
