Andreessen Horowitz Leads Netris' Series A to Accelerate Adoption of GPU Network Automation and Multi-Tenancy Across AI Cloud Operators Worldwide
Highlights
● Netris raised a $15M Series A led by Andreessen Horowitz. Partner Guido Appenzeller
led the round and is joining the Netris board.
● In the last 12 months, Netris experienced 800% ARR growth, enabling network
automation and multi-tenancy for 35+ AI clusters across the world’s largest neoclouds,
sovereign AI operators, and AI factories.
● AI cloud operators worldwide are standardizing on Netris' NAAM platform — Network
Automation, Abstraction, and Multi-Tenancy — the next generation of network
automation, succeeding SDN and intent-based networking, built for the multi-layer
network fabrics GPU clusters require.
● Netris has built an extensive AI infrastructure ecosystem, anchored by NVIDIA and
spanning other GPU and networking vendors, as well as compute and PaaS vendors,
including Mirantis, Rafay, Red Hat, Spectro Cloud, and vCluster, and AI platform
providers like HPE. Within it, Netris is the core network automation and multi-tenancy
layer. Together, they enable operators with a stack to launch, operate, and monetize
GPU clouds.
● The round will accelerate Netris' lead in network automation for GPU clusters as AI cloud
operators worldwide are building out the largest infrastructure expansion in history.
The Largest Infrastructure Buildout in Human History
AI will require trillions of dollars in investment, with only a few hundred billion deployed so far.
IDC projects the AI infrastructure market will reach $758 billion by 20291, with AI generating
$22.3 trillion in global economic impact by 20302. For operators racing to capture that market,
every idle GPU is lost revenue, provisioning delays directly hit time-to-first-revenue, and
cloud-provider-grade capabilities are table stakes to win and keep customers.
Addressing Network Complexity
Network automation is where operators get stuck. A single GPU server carries at least 3
North/South, 16 East/West, and 4 NVL72 connections, and every time a tenant is added,
resized, or removed, the network must be reconfigured in concert across every layer at once —
sometimes hundreds or thousands of switches at a time. One misconfiguration can take a
cluster down or leak one tenant's data to another. Netris NAAM is the leading platform for many
of the world’s largest AI clouds, automating network operations and enforcing hard
multi-tenancy on networking hardware, so operators can securely share GPUs across tenants.
Chosen Across the AI Infrastructure Landscape
Netris has been chosen by AI cloud operators worldwide, now with 35+ live deployments:
high-growth neoclouds, including Lightning AI, STN, Boost Run, and TensorWave; sovereign AI
cloud providers, including TELUS, DCAI, and YOTTA; AI factories, including Foxconn-backed
Visionbay.ai, operator of Taiwan's largest GPU cluster, and Firmus, operator of Australia's
largest renewable-powered sovereign AI factory; and AI platform providers like HPE, which
delivers a full-stack AI solution for customers in research, education, and state and local
government.
Growth & Scale
In the last 12 months, Netris experienced 800% ARR growth. The company now has 35+ live
deployments at many of the largest neoclouds, sovereign AI operators, and AI factories in the
world — more live deployments than all other network automation vendors combined. Netris
operates teams across the US, UK, Taiwan, Australia, Armenia, and India, with Singapore
opening in 2026.
Why AI Clusters Demand a New Network Automation Foundation
AI clusters run across multiple network fabrics simultaneously — Ethernet (including NVIDIA
Spectrum-X), NVIDIA Quantum InfiniBand, NVL72, NVIDIA BlueField DPUs, and virtual and
edge networking — each with its own control plane and operational semantics. Legacy
approaches were never built for this. Building network automation in-house takes years and
breaks with every new reference architecture, and traditional controllers and fabric managers
lack multi-tenancy and the cloud-provider functionality AI operators require.
The Next Generation of Network Automation
Netris' NAAM platform — Network Automation, Abstraction, and Multi-Tenancy — succeeds
SDN and intent-based networking. It gives operators a single control plane across every fabric,
with hard multi-tenancy enforced on networking hardware. Operators launch GPU clouds in
weeks, provision tenants instantly with isolation configured automatically, and maximize GPU
utilization by dynamically reallocating capacity across tenants.
"Every era of computing has needed a new networking foundation — first for the
virtualized data center, then for the cloud, and now for AI," said Guido Appenzeller,
partner at Andreessen Horowitz. "GPU clusters run across many fabrics at once,
and legacy automation was never built for that. Netris is the platform AI cloud
operators standardize on to solve it, and we are excited to partner with them on this
journey."
AI Infrastructure Ecosystem
Netris has built an extensive AI infrastructure ecosystem, anchored by NVIDIA and spanning
other GPU and networking vendors, as well as compute and PaaS vendors, including Mirantis,
Rafay, Red Hat, Spectro Cloud, and vCluster, and AI platform providers like HPE. Within it,
Netris is the core network automation and multi-tenancy layer. Together, they enable operators
with a stack to launch, operate, and monetize GPU clouds.
The Road Ahead
This Series A round accelerates Netris' lead in network automation for GPU clusters as AI cloud
operators build out the largest infrastructure expansion in history. Netris will use the funding to
expand its team and global presence and to grow its partner ecosystem as AI infrastructure
scales worldwide.
"Netris spent years building the platform AI cloud operators now standardize on," said
Alex Saroyan, CEO and co-founder of Netris. "That foundation is why we've reached 35+
live deployments at many of the largest AI clouds in the world and built the ecosystem
around them. Andreessen Horowitz has a long track record backing category-defining
infrastructure companies. Martin Casado, Raghu Raghuram, and Guido Appenzeller
revolutionized networking for datacenters. Netris is doing the same for AI.”
About Netris
Netris is the leading provider of network automation and multi-tenancy for AI infrastructure,
