AI networking firm Aria Networks raises $125 million in funding

Aria Networks said on Tuesday it has raised $125 million in its first series funding round, as the startup seeks to develop its AI networking infrastructure of artificial intelligence.

Aria's network is designed to ‌work with ⁠any ⁠AI chip on the market, Nvidia Google, giving companies ​the flexibility to upgrade or switch hardware over time without overhauling ​their entire network infrastructure.

Founded in 2025, Aria Networks is backed by Sutter Hill Ventures, Atreides Management, Valor Equity ⁠Partners, and Eclipse ‌Ventures.


Gavin Baker, managing partner at Atreides, ​has joined ​Aria's board, along with Stefan Dyckerhoff ⁠of Sutter Hill and Aria's founders.

The company also announced the availability of what it calls the world's first AI-native network, built to help AI data centers run more efficiently and at lower cost. Its core focus is "token efficiency", a ‌measure of a data center costs.

Tokens are a measure of how ​much text ​an AI ⁠model can process or remember during a single interaction. A token roughly corresponds to a short piece ​of text, such as part of a word.

Palo Alto-based Aria said it already has customer orders in hand and is actively deploying.
