Bryant Chou co-founded Webflow, which today powers around 1% of all websites on the internet. Now he’s back in the current YC batch with Ploy, an AI-powered website and marketing platform that doesn’t just build your site — it connects to your analytics, CRM, and search console to optimize your marketing while you sleep. In this episode of the Lightcone he explains how he built Ploy to be “anti slop,” how building today compares to his first startup, and why founders with domain expertise are making a comeback.
