Aria Networks Raises $125M for AI Switch Tech

Aria Networks, a startup building switches for AI clusters, has raised $125 million from Sutter Hill Ventures, Atreides Management, Valor Equity Partners and Eclipse Ventures. The funding coincides with the launch of its Deep Networking product portfolio, featuring 800G and 1.6T Ethernet switches with advanced packet buffering and a custom SONiC-based operating system. The company's software stack includes a telemetry engine that collects hardware data claimed to be up to 10,000 times more detailed than competing tools, with AI agents automating tasks like load balancing and congestion management. Aria says it already has customer orders and is deploying its technology to early adopters.
