Celestial AI was a Santa Clara, California silicon-photonics company and the creator of the Photonic Fabric optical interconnect technology platform, which replaces electrical links between compute and memory with light in order to scale AI accelerators within a package, package-to-package, and across racks. The company raised more than $515 million across Series B and Series C rounds and introduced the Photonic Fabric Module, an SoC carrying optical interconnect in the middle of the silicon die. Marvell Technology completed its acquisition of Celestial AI on 2 February 2026 in a cash-and-stock deal reported at approximately $3.25 billion; the technology and team were folded into Marvell's Data Center Group and Celestial AI no longer operates as an independent entity. Its product was semiconductor hardware and IP sold to hyperscalers and accelerator vendors, not software, and it never published a developer program, public API, SDK, or machine-readable API contract.
