Aria Networks Raises $125M Series A for AI Data Centers

Aria Networks, a Palo Alto-based AI networking startup founded in 2025, has secured $125 million in its first Series A round. The company aims to deploy AI-native networking infrastructure for modern data centers, backed by Sutter Hill Ventures, Atreides Management, Valor Equity Partners, and Eclipse Ventures.

Aria Networks has raised $125 million in its first Series A funding round. The Palo Alto-based startup, founded in 2025, is building what it calls the world’s first AI-native network, specifically designed to meet the surging demand for data center capacity driven by the rapid adoption of artificial intelligence.

The round is led by Sutter Hill Ventures, with participation from Atreides Management, Valor Equity Partners, and Eclipse Ventures. Moreover, Gavin Baker, managing partner at Atreides, has joined it’s board of directors. He is joined by Stefan Dyckerhoff of Sutter Hill Ventures, alongside Aria’s founding team.

At its core, Aria Networks is tackling a quiet but critical bottleneck in AI deployment: the network infrastructure inside data centers. As AI workloads grow more demanding, traditional networking stacks built for a different era are increasingly falling short. To address this, Aria has introduced its Deep Networking platform, which the company describes as fundamentally different from how conventional networks operate. Rather than building for a single vendor’s chips, Aria’s system is designed to work with any AI chip on the market including processors from Nvidia and Google. Consequently, companies can upgrade their hardware or switch chip vendors over time without having to overhaul their entire network infrastructure.

Central to Aria’s pitch is a metric it calls token efficiency, a measure of a data center’s AI output relative to its running costs. According to the company, improving token efficiency directly relates to Model Flop Utilization (MFU) and cost per token, both of which translate into real-world savings for AI operators at scale. Furthermore, Aria’s switch platform built from the ground up on AI-native SONiC delivers 800GbE and 1.6T switching in both liquid-cooled and air-cooled form factors, with no vendor lock-in.

Importantly, Aria Networks is not a pre-revenue concept. The company already has customer orders in hand and is actively deploying its platform in production environments. Alongside this funding announcement, Aria confirmed the general availability of its “Networks that Think” platform.

Aria was co-founded by Mansour Karam (CEO) and Subhachandra Chandra (CTO). Karam previously founded Apstra, an AI-driven networking company that was acquired by Juniper Networks in 2021 for approximately $190 million. Both founders are veterans of Arista Networks, and the broader team draws talent from Meta, Google, and Juniper.

As demand for AI infrastructure continues to accelerate, the networking layer inside data centers is emerging as just as critical as the chips themselves. The global AI data center networking market stands at $12.8 billion in 2026 and is projected to grow at a 24.2% compound annual growth rate through 2035. Therefore, Aria’s Series A is not only a vote of confidence in the company, it reflects a broader industry recognition that the pipes connecting AI systems must evolve alongside the models they serve.
