Celestial AI

Celestial AI is the creator of the Photonic Fabric™, which unleashes advancements in AI.

Today’s advanced AI models require exponentially increasing memory capacity and bandwidth, as Large Language Models (LLM) including GPT-4 used for ChatGPT and Recommendation Engines are memory bound rather than compute bound. Celestial AI’s Photonic Fabric provides the foundational technology for optically scalable, disaggregated data center compute and memory, to unleash advancements in AI. Celestial AI’s Photonic Fabric technology platform delivers optical connectivity performance levels that are ten years more advanced than existing technology offerings. Fitz Gate led the seed extension round with MIT Engine Fund, Tyche Partners, IMEC (foundry) and M Ventures (Merck) participating. Since then the company has made great strides with its technology and raised a $56M round led by Koch Disruptive Technologies, one of the largest deep tech investors in the world; a $100M Series B round co-led by Temasek’s Xora (Temasek is the sovereign wealth fund of Singapore) and IAG Capital Partners; and a $175M Series C round led by US Innovative Technology Fund valuing the company at $1.2B.
