# Celero Raises $275M Series C at $3B+ Valuation for AI Data Center Networking Chips

> Celero Communications has raised a 275 million dollar Series C at a valuation above 3 billion dollars, led by Alphabet's CapitalG alongside Atreides Management and Valor Equity Partners, bringing total funding to 415 million dollars. The company builds coherent digital signal processor chips for the connections between AI data centers. The technical claim behind the round is a 2nm coherent DSP design that supports up to 3.2 terabits per second per port with lower latency and power draw, and can carry data across more than 100 miles of fiber. As AI workloads spread across multiple sites, moving data quickly between them has become a real bottleneck, not just a nice-to-have. That is the thesis investors are backing: the AI buildout is not only about GPUs but about the unglamorous networking that stitches them together. Celero is positioning itself in that interconnect layer, and a raise led by Alphabet's growth fund is a signal that the money sees data-center-to-data-center bandwidth as a durable place to bet.
