Bryant Chou (@bryantchou) co-founded Webflow, which today powers around 1% of all websites on the internet.

Now he's back in the current YC batch with @ployai, 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 @LightconePod, 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.

A bit of déjà vu at @ycombinator Demo Day earlier this week. (sharing in case you're curious)

Webflow went through YC back in 2013. A lot of people have been asking: why do YC again with @ployai? A few reasons ...

3/ Benefit from youth

I am a bit of a boomer now. Double the age of YC founders. But they've taught me so much about how to use AI, growth tactics, new mediums for distribution.

Spending time with folks half you age is the best longevity hack.

if you're a repeat (and older) founder like me, definitely consider doing YC again. It's even better now, trust —

2/ Working with the best in the biz.

@garrytan served as my group partner again. @greybaker always gave gas feedback. Companies are hitting real traction faster than ever right now… and having advisors who've watched thousands of startups do exactly that is a cheat code for early growth.

1/ Getting close to AI-pilled early users.

We think Ploy is a huge unlock for early-stage founders. Setting up a company website looks really different these days. More and more founders vibe-code a quick site instead of reaching for a traditional CMS like Webflow or Framer. But once it's up, it tends to just sit there while they go heads-down on product and customers. Many sites look the same.

Also by selling to the most cracked user base I have to build something cutting edge that meets the bar of these founders that live 2 years in the future. Now is definitely the time to be inventing the future, vs. iterating on incremental. Selling to YC founders ensures that.
