Unspam origin: law meets email spam

In this episode of The Slow Hunch, I spoke with Matthew Prince, the co-founder and CEO of Cloudflare. Since 2010, Matthew and his team have built Cloudflare into one of the most important companies on the internet: powering and protecting vast portions of global traffic. 

Our conversation explores the through-line from Matthew’s initial hunch about fixing the flaws of the early internet, to Cloudflare’s present role as a foundational infrastructure provider.  

We talk about the early experiments and risks that have shaped Cloudflare’s culture, and how those small bets compounded into a truly iconic company today. Matthew shares stories from the company’s pre-IPO days, the decision to make encryption free, and how Cloudflare’s infrastructure ended up running two of the internet’s thirteen root servers. Toward the end, we dive deep into the transition from a search-driven internet to an answer-driven one, and what that means for publishers, creators, and the future business model of the web.

It was especially fun to record this one with Matthew, who I’ve known since USV’s investment in Cloudflare’s Series C back in 2013. 

Hope you enjoy!
