Our take

Chip production forms the backbone of our modern, digitally enabled economy; being important enough to be of major geopolitical interest, and garnering billions of investment from the US alone. Celestial AI has developed a proprietary technology platform which enables high-performance computing solutions, using light for data movement within and between chips, enabling it to deliver "the next generation of AI acceleration products".

The company's photonic-electronic technology has sparked significant interest in the AI hardware space, and has resulted in it raising impressive investment. This supported the expansion of its engineering workforce and supplier relationships, as well as accelerated product development. In 2026, Celestial AI was acquired by Marvell Technology which marks the next chapter in its journey.
