Celero Communications, a prominent innovator in high-performance coherent DSP (digital signal processor) technology for AI infrastructure, has announced that it successfully secured a total of $140 million in funding. This milestone includes a recent $100 million Series B round led by CapitalG, Alphabet’s independent growth fund, along with $40 million from earlier Series A and seed rounds spearheaded by Sutter Hill Ventures and supported by Valor Equity Partners, Atreides Management, Maverick Silicon, and others. With this substantial backing, Celero is now strategically positioned to serve the rapidly expanding market for advanced coherent optical connectivity.
Moreover, the company’s cutting-edge coherent DSP platform plays a crucial role in powering signal processing across large-scale AI systems. As AI architectures continue evolving from single-rack deployments to massive networks spanning millions of AI accelerators and interconnected data centers, Celero’s technology ensures unmatched bandwidth efficiency. In addition, the platform’s superior performance, energy efficiency, and cost advantages are setting the benchmark for next-generation accelerated computing environments.
