Miami, Florida-based doxx.net has raised $38 million in a Series A funding round led by Andreessen Horowitz with participation from Animo Ventures and Focal.vc. The company was founded in 2025 by the serial founder and hacker at heart Barrett Lyonsand operates on six continents.
The new funding was announced at the same time as the announcement doxx.net The Agentic Defined Networking (ADN) platform, currently in open beta, has been announced. This platform provides agents with an environment with defined connectivity and built-in threat protection that prevents them from reaching known malicious targets while browsing and acting on a user’s behalf.
Today, agents surf the Internet, communicate, access services and act on behalf of their user. However, these agents cannot necessarily distinguish between secure information and actions and unsafe information and actions while working with their users’ accounts and permissions. This is the security issue that ADN is addressing.
“The industry sells privacy as a feature while routing your traffic through leased infrastructure that it doesn’t own and can’t audit,” explains Barrett Lyon, founder and CEO of doxx.net. “We’ve physically built something different: a platform where privacy comes from the architecture itself, not a policy document. We do this so that people and agents using the network, rather than third parties, set the terms of their privacy. They know what you’re looking for, where you’re going, and who you’re talking to. We don’t know that. And we’ve built the network so that we never can.”
ADN is a parallel, private network platform that allows both human users and AI agents to connect, communicate and browse without relying on central intermediary servers. Such servers cause problems. They provide a single point of interception and surveillance; Artificial privacy guarantees, which are typically policies rather than facts, increase the potential for the agent to reach a malicious target and are vulnerable to censorship and blocking.
However, ADN offers serverless P2P communication with end-to-end messaging and file transfers; built-in threat protection that blocks malicious targets, malware and phishing sites; Agent integration and API control, a parallel internet infrastructure, and privacy and anti-tracking features. It has native apps for iOS, macOS and Android with support for Windows and Linux, all running on its global backbone.
“The Internet was never designed for privacy,” adds Joel De La Garza, partner at Andreessen Horowitz and board member at doxx.net. “doxx.net has built a one-stop data protection stack that provides truly private security and communications capabilities, allowing humans and AI agents to run on a network that is private by architecture, not marketing promise.”
The company allows its customers to use this private network with its own naming system. A parallel Internet ecosystem offers 196 custom TLDs and its own certificate authority. Customers’ ADN networks resolve domains the public Internet has never heard of, without third-party involvement.
It provides users and agents with DNS-level threat protection that blocks known and emerging malicious targets before an agent or person connects. Since December 2025, doxx.net says it has blocked more than 38 million threats in the closed beta.
The platform allows customers to operate end-to-end on doxx.net’s infrastructure with their own IP range and ASN, their own DNS root, their own certificate authority, their own local AI models and their own bare metal servers. It does not require usernames, passwords or other personal information from its users – accounts are created through proof of work.
