Let's not forget how Cloudflare got started...
The Department of Homeland Security offered to buy the data from Project Honeypot (run by Matthew Prince and Lee Holloway), and they sold it to them for $20,000. Michele Zatlyn (a classmate of Prince) said "if they'll pay for it, other people will pay for it."
"And so the idea for Cloudflare was born, with Ms Zatlyn as its third co-founder." [with Prince and Holloway]
