Rockstar🎓
Top SchoolDexter Horthy is a Silicon Valley founder and seasoned engineering leader with 11 years of experience building developer-focused products and customer-facing platforms. He currently leads HumanLayer (YC F24), an SDK and API that lets AI agents loop humans into approvals and feedback, after evolving his prior startup Metalytics into the current product. Dexter has deep hands-on experience across engineering, product, and customer success from early core engineering roles to VP-level leadership at Replicated, and he advises Prefect on developer tooling and orchestration. Based in San Francisco with a BA in Physics from the University of Chicago, he combines systems-level technical rigor with product sensibility and a pragmatic focus on human-in-the-loop safety for AI. An oft-overlooked strength is his background bridging low-level platform work and go-to-market roles—making him equally comfortable shipping code and shaping customer outcomes.
