Chip Startup Celestial AI Lands Massive $175M Series C


Celestial AI, a startup specializing in optical interconnectivity, has secured a substantial $175 million in its Series C funding round, with the US Innovative Technology Fund, led by Thomas Tull, taking the lead. The company’s photonic fabric platform addresses the growing demand for compute power and memory capacity in the age of generative AI, providing a solution that separates compute and memory to enhance the efficiency and speed of processing extensive AI tasks.


Founder and CEO Dave Lazovsky expressed confidence in Celestial AI’s disruptive potential, noting the critical need for increased I/O bandwidth and memory capacity to support advanced AI models. The funding round saw participation from several notable investors, including AMD Ventures, Koch Disruptive Technologies, Temasek, Samsung Catalyst, and Porsche Automobil Holding, among others.


This latest funding milestone follows Celestial AI’s successful $100 million Series B round in June last year, bringing the total raised by the Santa Clara-based company to nearly $339 million. The significant investments in Celestial AI reflect the broader trend of heightened investor interest in the semiconductor industry, particularly in companies developing technologies crucial for the expanding AI sector.
