TL;DRNetris raised $15M from a16z for its GPU network automation platform, now live at 35-plus clusters with 800 percent annual revenue growth.

Netris, a Santa Clara startup that automates the networking layer inside GPU data centres, has raised $15 million in a Series A round led by Andreessen Horowitz. The round follows what the company says is 800 percent annual recurring revenue growth and more than 35 live deployments at GPU clusters around the world, including operations run by Lightning AI, Foxconn-backed Visionbay, Hewlett Packard Enterprise, TensorWave, and Telus.

The problem Netris addresses is not the one that gets the most attention in the AI infrastructure boom. Neoclouds have raised billions of dollars to buy GPUs and build data centres, but getting those facilities operational requires configuring the network fabric that connects thousands of servers, a process that can take months and leave expensive hardware sitting idle.

A single GPU server carries at least three north-south connections, 16 east-west connections, and four NVL72 links, according to the company. Every time a tenant is added, resized, or removed, the network must be reconfigured across every layer simultaneously, sometimes across hundreds or thousands of switches at once. One misconfiguration can take a cluster down or leak one customer’s data to another.
