Netris raises $15M from a16z to automate AI data center networking

Netris raised $15 million in a Series A round led by Andreessen Horowitz. The network automation startup will use the money to expand its engineering and commercial teams and open a Singapore office. The company also plans to build partnerships with other technology providers. The round closed June 25.

Netris built the NAAM platform, which automates the networking layer for large-scale AI clusters. The platform handles multi-fabric environments, managing both Ethernet and InfiniBand networking within the same deployment. It also handles multi-tenant isolation, critical for cloud operators that need to keep customer workloads separate on shared infrastructure.

Netris is the first independent software vendor validated by NVIDIA for AI network automation. Nvidia, which validated Netris, holds a Moderate Alpha Score of 65, according to AlphaScala data.

The company reported 800% growth in annual recurring revenue over the past year. It has completed more than 35 production deployments and claims a 12% share of the neo-cloud market by cluster count. Prior to this Series A, Netris had raised under $6 million total. The company had previously announced 622% year-over-year ARR growth in 2025, with 15 AI cloud operators onboarded in 10 months.

Guido Appenzeller, an a16z partner, will join the Netris board. Netris counts Lightning AI and TELUS among its customers, alongside partnerships with NVIDIA, Red Hat, and HPE. CEO Alex Saroyan brings over 25 years of networking experience, with previous stints at Cisco and Ruckus.

The Singapore office signals that Netris is looking beyond North America. Neo-cloud refers to the wave of specialized AI cloud providers building GPU-first infrastructure, as distinct from the big three hyperscalers. Netris said its 800% ARR growth and 12% market share place it as a leading player in that segment.
