THE CRUNCH
Miami-based doxx.net has raised $38 million in a Series A round led by Andreessen Horowitz, with Animo Ventures and Focal.vc also taking part. The startup, founded in 2025 by Barrett Lyon, announced the funding at the same time as its Agentic Defined Networking (ADN) platform, which is now in open beta. ADN gives AI agents a network environment with defined connectivity and built-in threat protection, intended to stop them reaching known malicious destinations while they browse and act on a user's behalf.
The money arrives alongside the launch of the company's Agentic Defined Networking (ADN) platform, now in open beta. ADN is described as a parallel, private network that humans and AI agents can use without central intermediary servers, which the firm argues create single points for interception and surveillance. It offers peer-to-peer messaging and file transfers, built-in protection that blocks malicious destinations, malware and phishing sites, and API controls for agent integration.
The platform runs on infrastructure doxx.net says it owns outright, including its own IP space, DNS root, certificate authority and bare-metal servers, with 196 custom top-level domains the public internet cannot resolve. Accounts require no usernames, passwords or personal details and are created by proof-of-work. The company claims to have blocked more than 38 million threats in closed beta since December 2025, a figure that comes from doxx.net itself.
The pitch is aimed squarely at the agentic AI problem: software that browses, communicates and acts on a user's behalf cannot reliably tell safe destinations and actions from unsafe ones while wielding that user's authority. Founder and CEO Barrett Lyon, who started the firm in 2025, says privacy should come from the architecture rather than a policy document, so users and their agents, not third parties, set the terms.
