Alphabet's CapitalG, Atreides Management and Valor Equity Partners led the round, with Sutter Hill Ventures and Maverick Silicon returning to back the coherent DSP startup.
Celero Communications Inc. has raised $275 million in Series C funding to advance its data center networking chip business, the startup announced. The round was led by CapitalG, the growth investment fund of Alphabet Inc., together with Atreides Management and Valor Equity Partners. Sutter Hill Ventures and Maverick Silicon, both returning backers from earlier rounds, also took part in the financing.
Celero's core focus is the coherent digital signal processor, a category of silicon designed for the networking layer of the data center. Coherent signaling techniques, long associated with high-speed optical transmission, are increasingly relevant as operators push more data between servers, racks and facilities. Celero is positioning its processors for exactly this environment, where signal integrity and bandwidth density determine how efficiently large compute clusters can be connected. For a startup, the category offers a direct line into the buildout of AI-oriented infrastructure, where networking bandwidth has become a gating factor alongside compute itself.
The composition of the syndicate stands out. CapitalG's involvement links the startup to Alphabet Inc., one of the largest operators of data center infrastructure globally. Lead positions for Atreides Management and Valor Equity Partners bring fresh growth-stage capital alongside the strategic fund. And the continued participation of Sutter Hill Ventures and Maverick Silicon suggests existing shareholders saw enough in the company's progress to double down rather than step aside at the Series C stage.
Celero also disclosed an updated valuation in connection with the financing, though the announcement did not detail how the $275 million will be deployed. With the round closed, the company heads into its next phase with backing from a blend of hyperscale-linked, growth and specialist silicon investors — a capital base matched to the data center networking opportunity it is chasing.
