Networking built for AI clusters

SkyHammer is a scale-up architecture intended to reduce communication bottlenecks between accelerators, memory and storage. Upscale uses open networking standards and software so operators can build clusters without relying on a single proprietary interconnect.

From development to commercial delivery

The Series A follows a seed financing announced in 2025. At the January announcement, the company was preparing its full-stack platform for deployment with hyperscalers and AI infrastructure operators; product shipments remained planned for later that year.
