Cloudflare, a company whose technology helps companies distribute their content and keep it available online, has filed to go public. On Thursday the company's filing kicking off the process of its initial public offering became publicly available.

In the first half of 2019, Cloudflare had a $36.8 million net loss on $129.2 million in revenue, according to the IPO prospectus. That revenue figure was up 48% from the first half of 2018, and the loss was up 13%.

The company plans to start trading under the ticker symbol "NET." The lead underwriters are Goldman Sachs, Morgan Stanley and JP Morgan.

Cloudflare's competitors include Cisco, Zscaler, content-delivery network providers Akamai and Fastly and cloud providers like Amazon and Microsoft. The San Francisco-based company says 20 million internet properties use its services.

The company had 74,873 paying customers at the end of the first half of 2019, with 408 of them contributing more than $100,000 in annualized billings. The company's clients include cloud infrastructure providers like DigitalOcean and IBM, along with software companies like Discord, Marketo and Zendesk.

Chinese web company Baidu is also a customer, and it provides Cloudflare with a network presence in China. Terms of Cloudflare's agreement with Baidu conclude at the end of 2020, but it can terminated at the end of 2019 under certain circumstances. "The risk of such an early termination event may have increased during the current environment of economic trade negotiations and tensions between the Chinese and U.S. governments," Cloudflare says in the prospectus.

Cloudflare has been involved in several controversies, most recently including the move to stop providing services for message board 8Chan. In 2017 it stopped backing a neo-Nazi website, the Daily Stormer. Cloudflare said that it received negative feedback on those decisions and that potential customers elected to not subscribe to its services as a result.

"Activities of our paying and free customers or the content of their websites or other Internet properties, as well as our response to those activities, could cause us to experience significant adverse political, business, and reputational consequences with customers, employees, suppliers, government entities, and others," the company said in the filing.

Cloudflare's investors include Fidelity, NEA and Pelion Ventures and Venrock.

Matthew Prince, Cloudflare's co-founder and CEO, owns 20.2% of the company's class B shares, and co-founder and COO Michelle Zatlyn has 6.8%.

In a letter to prospective shareholders, they said the IPO code name, Project Holloway, is a reference to Cloudflare's third co-founder, Lee Holloway. "Tragically, Lee stepped down from Cloudflare in 2015, suffering the debilitating effects of Frontotemporal Dementia, a rare neurological disease," they wrote. Trusts affiliated with Holloway own 18% of Cloudflare's class A shares.
