Celero Communications

Celero is focused on designing next-generation coherent Digital Signal Processor (DSP) solutions that translate light bursts from fiber-optic cables into electrical signals for computing networks. This technology addresses the growing demand for faster, more power-efficient data connections driven by the expansion of massive AI data center campuses by tech giants like Alphabet and Meta. The company's chips utilize new embedded algorithms to process light over existing fiber-optic infrastructure more efficiently, aiming to enhance performance and reduce costs for large-scale AI workloads. This approach seeks to bridge the performance gap between existing campus-level networking chips, which lack long-distance capabilities, and traditional telecommunications chips, which are often too expensive and power-intensive for widespread AI use.

Celero Communications has secured a total of $140 million in funding. This includes a $100 million Series B round led by CapitalG, Alphabet's independent growth fund, and a previously undisclosed $40 million Series A round led by Sutter Hill Ventures, with participation from other investors. The company's clients are large-scale data center operators, particularly those building out AI infrastructure.
