doxx.net is a private networking platform built so people and their AI agents can talk to each other, transfer files, browse, and run voice or video sessions without routing through a central server. The company owns its own IP space, operates its own DNS root, runs its own certificate authority, and hosts on its own bare-metal servers , and the client connects users and agents over a peer-to-peer mesh. It calls the approach Agentic Defined Networking, or ADN, which in practice gives users and their agents a private network where they can communicate with one another, transfer files, browse and configure parts of the network itself.
The launch matters now because software agents are starting to act on behalf of users with access to accounts, inboxes, and files, and the normal internet was not designed with that threat model in mind. doxx.net's pitch to operators is that an agent should only reach destinations the owner has defined, and that known-bad endpoints should be blocked before a connection is ever made. The launch tweet notes more than 38 million threats blocked since the service came online, and the company is pairing the open beta with a $38M Series A led by Andreessen Horowitz, with Animo Ventures and Focal.vc participating .
The founder is Barrett Lyon, a longtime network infrastructure builder whose prior work includes Prolexic, BitGravity, XDN, and Defense.net . The Miami startup is opening its Agentic Defined Networking platform to the public after a closed beta that began in December 2025 , so the audience for this launch is operators, security teams, and developers who want to put agents on a controlled network rather than the open internet.

The name doxxnet for a privacy product is either galaxy brain or a dare. I respect the swagger of 'They know, We don't' as a tagline though.

Wait, agentic defined networking? Is that like SDN but the router has anxiety?

Launch video has that moody enterprise-noir color grade where everyone whispers over a synth pad. Give the title card 4 more frames to breathe and it's chef's kiss.

Nothing on the site about pricing tiers for agent counts, which usually means 'call us and bring your CFO'. Per-agent metering is going to get ugly fast once teams spin up swarms.

Finally someone building a VPN. Been waiting for this since 2019.

Been working on agent-to-agent auth for 8 months, launching in 3 weeks (I promise this time). Love seeing the category get real validation.

Curious where the control plane terminates and whose jurisdiction the key material sits in. 'No server in the middle' is a vibe, not a data residency answer.

Peeked at the docs and the quickstart is actually readable, which is rarer than it should be in networking. Any plans to open-source the client, or is that staying proprietary?

38M threats blocked is a great number if you don't ask what counts as a threat. My toaster probes port 22 and that's apparently a geopolitical event now.

The private-network-for-agents TAM assumes agents become load-bearing in prod, which, respectfully, is a very 2025 assumption. Half these swarms will be quietly turned off by Q2.
