Summary

Rockstar🎓
Top SchoolEvan Morikawa is an accomplished engineering leader and investor with 15+ years building and scaling AI, API, and infrastructure teams, most recently leading core launches at OpenAI including ChatGPT, GPT-4, DALL·E and developer APIs. Now a General Partner at Zero Shot Fund and building general-purpose robots at Generalist, he blends deep product engineering experience with early-stage startup instincts dating back to founding roles and Techstars. He has a strong track record designing large-scale systems—CDC pipelines, high-throughput event ingestion, inference and cloud infra—and shipped both developer-facing APIs and consumer-facing products. A prolific open-source contributor and former architect of Nylas Mail, he pairs front-end UX sensibilities with backend systems rigor and Rails-era contributions like improving ActiveRecord sharding tools. Based in San Francisco and an Olin alum, he’s as curious about AI and space as he is about comparative East/West coast pizza, and keeps an obsessively detailed calendar that doubles as a personal time log. That mix of technical breadth, operator experience, and genuine curiosity makes him a builder people trust to steer risky, high-impact systems.
