# CScale

> Optical scale-up interconnect designed to keep gigawatt-scale AI clusters communicating through link failures.

## Why it is interesting

CScale emerged from stealth with a $145 million Series C and strategic backing from NVIDIA and Intel Capital. The opportunity sits at a costly bottleneck in AI infrastructure: maintaining predictable, low-latency communication as accelerator clusters grow. The principal diligence gap is that CScale has not publicly disclosed product specifications, named customers or a commercial shipping timetable.
