What you likely need

You're at a rare intersection: a two-time exited founder (Stellate→Shopify, Spectrum→GitHub), prolific OSS creator (styled-components, react-boilerplate), and now shipping ChatGPT's apps platform at OpenAI. Festival events should compound your angel portfolio and OpenAI distribution while keeping you plugged into the dev-tools and AI-infra founders you naturally back. Lean toward small, technical rooms where you can both invest and recruit.
