Cornelis Networks Tech Stack

Lossless, congestion-free networking for AI and HPC at scale

Computer Networking Products Wayne, PA 51–200 employees Founded 2020 Privately Held

Cornelis Networks builds high-performance fabric architectures designed to eliminate congestion and packet loss in AI training and HPC workloads. The tech stack—heavy on Verilog, SystemVerilog, Ethernet protocol design, RDMA, and GPU-direct memory access—combined with active verification and silicon-validation projects, signals a company still in hardware bring-up phase. Senior engineering dominance and pain points around first-pass silicon success and verification closure indicate they're scaling infrastructure teams to ship their next-generation platform.
