Margins, CapEx, and Cash Flow

 Today we are breaking down the cybersecurity giant, Cloudflare. 

Today, Cloudflare controls over 20% of the world’s web traffic, and more impressively, absorbs 2.5mn cyber attacks per second.

My guest is Sam Eden, Investor at Square Peg’s Global Tech Fund. And while I understood on the surface what Cloudflare does, Sam helped me get into the weeds on how the digital pipes actually work.

So we go through the rise of Cloudflare and how they differentiated themselves vs. the incumbents and fellow upstarts. Through this story, Sam details the product offerings that led to Cloudflare's leading market share, and what growth looks like moving forward.
