Barrett Lyon Co-Founded doxx.net Raises $38M in Series A Funding

Why the Funding Matters

doxx.net will use the new funding to support the launch of its open beta platform and further develop its privacy-by-architecture networking infrastructure.

The platform is designed to provide defined connectivity and built-in threat protection for individuals, enterprises, and AI agents.

Who founded doxx.net?

doxx.net was founded in 2025 by Barrett Lyon.

The company is based in Miami, Florida.

Lyon previously pioneered the DDoS defense industry with Prolexic, which was acquired by Akamai, and has also worked on other security and networking companies.

The industry sells privacy as a feature while routing your traffic through rented infrastructure they don't own and can't verify," said Barrett Lyon, founder and CEO of doxx.net. "We physically built something different: a platform where privacy comes from the architecture itself not a policy document. We do that so people and agents using the network, not third parties set the terms of their privacy.

“The internet was never designed for privacy,” said Joel De La Garza, partner at Andreessen Horowitz. “doxx.net has built a one-stop privacy stack from first principles, delivering truly private security and communications capabilities, so humans and AI agents can run on a network that is private by architecture, not by marketing promise.”

Market and Business Growth

doxx.net launched the open beta of its Agentic Defined Networking platform alongside the funding announcement.

The company says its platform blocked more than 38 million threats during its closed beta period since December 2025.

Its infrastructure includes its own IP space and ASN, DNS root, certificate authority, local AI models, and bare-metal servers.
