The company priced at $15 on Thursday, Aug. 12, just above the range of $12 to $14 that Wall Street had targeted.
At its first trade, Cloudflare traded above $18.
Cloudflare has been in the news in the past year for its decision to terminate service for 8Chan after the mass shootings in El Paso, Texas, and Dayton, Ohio.
"8chan is among the more than 19 million Internet properties that use Cloudflare's service. We just sent notice that we are terminating 8chan as a customer effective at midnight tonight Pacific Time. The rationale is simple: they have proven themselves to be lawless and that lawlessness has caused multiple tragic deaths. Even if 8chan may not have violated the letter of the law in refusing to moderate their hate-filled community, they have created an environment that revels in violating its spirit," wrote Prince in a Cloudflare blog post on Aug. 5.
"One of the things that's unique about Cloudflare is that we have a version of our service that's free and so anyone can sign up. There are more than 20 million Internet properties that use our platform. And, for the most part, they are great organizations. The New York Stock Exchange as a customer, for example, and we're really proud of them. But every once in a while there are organizations that cross a line. And while I think that where our responsibility is different than a Facebook or a Youtube, at some level, there is a responsibility that we have for who our customers are and what they're doing online," Prince explained to TheStreet.
