Netris has raised its $15 million Series A, led by
@a16z.
Guido Appenzeller (
@appenz) led the round and is joining our board, with fellow a16z partners Martin Casado (
@martin_casado) and Raghu Raghuram (
@RaghuRaghuram) behind the investment. Together, they're the team behind the network virtualization that reshaped the modern data center — Nicira, NSX, VMware. They solved networking for the data center. Netris is doing it for AI.
Eight years ago, that bet looked wrong. We believed the network would become the hardest problem in computing, and that nobody outside the hyperscalers had the tools to solve it.
The hyperscalers had built that automation for themselves — armies of engineers, custom systems. Everyone else was stuck. So we built a platform to put it within reach of any operator.
Most investors didn't see it. Most of the industry didn't either. But the operators actually running networks did — they started choosing Netris long before AI was on anyone's roadmap.
Then the AI buildout hit, and the network became the bottleneck for the entire industry. A single GPU cluster runs across multiple network fabrics at once — Ethernet, InfiniBand, NVL72 — each with its own control plane, spanning hundreds or thousands of switches. None of it was built to work as one, and the automation tools that came before were never designed for it. One misconfiguration can take an entire cluster down.
It was the exact problem we'd spent years solving — and the platform was already built for it.
Netris automates network operations across every fabric and delivers true multi-tenancy through hard isolation (enforced on networking hardware). Operators can now run shared GPU clouds, maximize GPU utilization, and provision new tenants instantly.
In the last 12 months, Netris experienced 800% ARR growth and reached 35 live deployments and growing — more live deployments than all other network automation vendors combined. The largest AI clouds in the world have chosen Netris: neoclouds, sovereign AI operators, and AI factories.
Huge thanks to the Netris team, our customers, investors,
@nvidia, and our ecosystem partners, including
@MirantisIT,
@rafaysystemsinc,
@RedHat,
@spectrocloudinc,
@vclusterlabs, and
@HPE.
The AI buildout is just beginning. Netris has been ready for this for eight years.
