Celero Communications

Celero Communications is a fabless semiconductor company headquartered in Irvine, California, founded in 2024 by engineering leaders drawn from Marvell, Inphi, Broadcom and ClariPhy. The company designs coherent digital signal processing (DSP) silicon for high-bandwidth, low-power optical interconnect inside AI data centers, targeting the scale-up and scale-out optical links that connect large AI accelerator clusters, and it operates additional design centers in Canada and Argentina. Celero has raised approximately $140 million to date, including a $100 million Series B led by CapitalG, Alphabet's independent growth fund, following seed and Series A rounds led by Sutter Hill Ventures with participation from Valor Equity Partners, Atreides Management and Maverick Silicon. Celero sells hardware components rather than a developer-facing web service; its public web presence at celero.inc is served behind a Cloudflare managed bot challenge, so no developer, documentation, or API surface could be read during profiling.

Celero Communications is profiled on the APIs.io network. Tagged areas include Company, Semiconductors, Coherent DSP, Optical Interconnect, and AI Infrastructure.

  detail: Every path on celero.inc — homepage, /robots.txt, /llms.txt, /openapi.json and all four /.well-known/ probes — returns
    HTTP 403 carrying Cloudflare's cf-mitigated challenge header, so not one byte of the company's own site could be read,
    even through a rendering proxy; DNS shows only www (no api., docs., developer., portal. or status. host exists).
