About Shawn Wang
Shawn Wang, known as swyx, is a Singaporean based in San Francisco. He began his career in finance as a derivatives trader at Standard Chartered and a technology, media and telecom equities analyst at Balyasny Asset Management. He then moved into developer experience and developer relations roles at AWS, Netlify, Temporal and Airbyte, and he also cofounded Svelte Society.
He founded Smol AI, which makes the AI News newsletter. He is editor and podcast cohost of Latent Space. He is cofounder and CEO of AI Engineer, which runs the AI Engineer conferences and grew out of his 2023 essay The Rise of the AI Engineer. His site also says he works with Cognition, where he contributes to evaluation standards for coding agents.
swyx describes himself as a developer, founder and angel investor active in the AI and devtools community. In 2021 he published an index of angel investors who back devtools companies, and he ran the DevTools angels community. That repository is now archived and points to a successor AI angels list.
A 2024 podcast bio says he has angel invested in Airbyte, Railway, Supabase, Replay.io, StackBlitz, FlutterFlow and Fireworks.ai. Crunchbase lists 11 personal investments, mostly seed and pre-seed rounds. Dates and amounts are hidden behind its paywall.
CB Insights records swyx in the seed round of Confident Security on July 17, 2025. The round totaled $4.2M, with Decibel Partners, ex/ante and South Park Commons also investing. It also lists an earlier seed investment from April 2024 but does not name the company.
Crunchbase also lists Zeta Labs (pre-seed), Browserbase, Restate, Arcjet, Tab and LittleBird (seed). He has said in public that he is now focused on AI, and he still draws on his devtools go-to-market experience.
The public record points to pre-seed and seed rounds in developer tools and AI infrastructure and tooling. His angel activity has been tied to the devtools community, and he is based in San Francisco. He has not published a check size or fund size that we could find, so none is given here.
