Celestial AI has raised $100 million in series B funding led by IAG Capital Partners, Koch Disruptive Technologies, and Temasek’s Xora Innovation fund. Celestial AI is a developer of optical interconnect technologies. The company’s Photonic Fabric technology platform delivers optical connectivity performance levels that are reportedly 10 years more advanced than existing technology. Other investors in the round include Samsung Catalyst, Smart Global Holdings, Porsche Automobil Holding SE, The Engine Fund, imec.xpand, M Ventures, and Tyche Partners. Photonic Fabric is an optical interconnect technology designed to enable disaggregated, exascale compute and memory clusters. It is well suited for applications such as artificial intelligence models that require high levels of memory capacity and bandwidth, in addition to cloud services and data centers. Low-bandwidth, high-latency, and high-power electrical interconnects have served as consequential barriers to growth of profitable AI business models and advancements in AI. According to Celestial AI, the bandwidth delivered by Photonic Fabric is 25× greater and delivers 10× lower latency and power consumption than any optical interconnect alternative, such as co-packaged optics.
