## What Celero builds

Celero develops coherent DSP silicon for optical interconnects used in AI infrastructure.

As AI clusters scale, networking becomes a first-order infrastructure problem: accelerators can sit idle if data cannot move through the system quickly enough. That is why funding is flowing not only into GPU and data-center companies but also into optical, switching and interconnect suppliers.

## The competitive context

Celero belongs in the same broader VCT research cluster as companies such as Cornelis Networks, Fluidstack and other AI-infrastructure suppliers.

That does not mean they sell the same product. The useful common thread is the capital intensity and strategic value of the infrastructure layer around frontier compute.

## What is confirmed

The $275M round, $415M total raised and $3B-plus valuation are company-disclosed figures. VCT does not infer a more precise valuation than the company announced.
