Running a massive GPU data center is hard enough. Making all those machines actually talk to each other efficiently? That’s where things get really complicated, and really expensive.

Netris, a Santa Clara-based software company, just raised $15 million in a Series A round led by Andreessen Horowitz to tackle exactly that problem. The funding, announced on June 25, will go toward expanding the company’s engineering and commercial teams, opening a new office in Singapore, and building out ecosystem partnerships.

What Netris actually does

Netris built what it calls the NAAM platform, which stands for Network Automation, Abstraction, and Multi-Tenancy. It automates the networking layer so that large-scale AI clusters can be deployed and managed without a small army of network engineers hand-configuring everything.

The platform handles multi-fabric environments, meaning it can manage both Ethernet and InfiniBand networking within the same deployment. It also handles multi-tenant isolation, which is critical for cloud operators who need to keep different customers’ workloads separate on shared infrastructure.
