Overview
Cornelis Networks (Wayne, Pennsylvania) sells high-performance fabrics for AI and HPC clusters. It spun out of Intel in 2020 (Omni-Path lineage). Lisa Spelman became CEO in 2024 after a Data Center & AI role at Intel. On September 14, 2026 TechCrunch, SiliconANGLE, and the Philadelphia Business Journal reported a $205 million financing led by IAG Capital Partners. Round stage and valuation were not disclosed. Other investors were not named in those stories. SiliconANGLE said the company also announced Active Compute Fabric and a strategic collaboration with Qualcomm Technologies for rack-scale inference evaluation — not a disclosed cheque. Philadelphia Business Journal put headcount above 250. A company CMO claim of up to 50% less network traffic is from pre-production simulations. IAG Capital Partners does not have a Venture Capital Tracker /fund/ page.
Why Cornelis Networks is interesting
A $205 million check into cluster networking with no series letter and no mark. Cornelis is pitching in-fabric compute (Active Compute Fabric) as an open Ethernet/UALink alternative to Nvidia’s optimized stack. Qualcomm is a collaboration in the same-day coverage, not a named investor.
Product & use cases
End-to-end AI and HPC interconnect, including CN5000/CN6000 switches and Active Compute Fabric, which the company describes as putting programmable compute in the network path for scale-up and scale-out clusters.
- AI training and inference cluster networking
- HPC fabrics on open Ethernet / UALink / Ultra Ethernet
- In-network collective operations and KV-cache assembly (company claims)

Competitive landscape
Edge: Open-architecture fabric pitched against Nvidia’s tightly coupled networking stack — the diligence gap is the missing valuation and customer list, not whether Cornelis has a product name.
AI-cluster networking is a first-order cost and utilization decision. Cornelis is raising against Nvidia lock-in with open standards. Without a mark, customers, or a series letter, the $205 million print is a capacity raise, not a priced franchise.
-
NVIDIA networking (NVLink / Spectrum-X) incumbent
GPUs are optimized for Nvidia’s own software and fabrics. Cornelis is selling optionality, not a proven displacement.
-
Cisco / Arista incumbent
SiliconANGLE frames Cornelis against established data-center networking vendors as well as AI-specific fabrics.
