Eliyan Raises $145M for AI Interconnect Tech

In a significant validation of its technology addressing critical AI infrastructure bottlenecks, Eliyan Corp. has successfully closed a $145 million Series C funding round. This substantial capital infusion propels the Silicon Valley-based startup into unicorn status, with its valuation now reaching $1 billion. The round was spearheaded by Seligman Ventures, with participation from strategic investors Cisco Ventures and Lumentum, underscoring the market's confidence in Eliyan's approach to high-speed data flow for artificial intelligence workloads.

The core challenge Eliyan aims to solve lies in the escalating demands placed on data centers by increasingly complex AI models, particularly large language models and agentic applications. As these systems require massive computational power, the interconnectivity between AI accelerators, memory, and networking components becomes a significant performance constraint. Traditional interconnect solutions struggle to provide the necessary bandwidth and power efficiency, leading to throttled performance and underutilized processing capabilities. This funding signifies a strong belief that Eliyan's technology is key to unlocking the full potential of next-generation AI hardware.

Eliyan's innovative solution centers on advanced electro-optical interconnects, including its proprietary NuLink PHYs and NuGear chiplets. These components are engineered to facilitate ultra-fast, die-to-die, chip-to-chip, and rack-to-rack communication. By drastically enhancing bandwidth capacity and improving power efficiency, Eliyan's technology enables data centers to build highly distributed and co-packaged computing fabrics. This architecture allows chips to operate at their peak computational capacity without a proportional surge in energy consumption, a crucial factor in managing the operational costs of large-scale AI deployments.

Ramin Farjadrad, co-founder and CEO of Eliyan, highlighted the fundamental architectural shift occurring in data centers driven by AI. "Traditional system connectivity approaches are reaching their limits as compute, memory, packaging, and networking become increasingly intertwined," Farjadrad stated. "Eliyan was founded to address these challenges at the architectural level. This financing will accelerate our product development, customer adoption, and ecosystem expansion, enabling us to power the next generation of AI infrastructure." The company's extensive patent portfolio, reportedly exceeding 100 patents, further bolsters its technological differentiation.

The newly acquired capital will be strategically deployed to advance Eliyan's research and development initiatives, focusing on creating even more sophisticated and faster interconnect technologies. Concurrently, the company plans to scale its manufacturing operations and cultivate a broader partner ecosystem to ensure widespread compatibility of its chiplet solutions. Eliyan has already seen promising engagement, with its technology undergoing evaluation and initial deployment by major hyperscalers, AI accelerator manufacturers, and memory chip suppliers, signaling strong market traction.

Umesh Padval, managing partner at Seligman Ventures, commented on the startup's deep technical expertise and its potential to redefine AI data center performance. "While optical interconnects may not be the most visible component, they are becoming a critical determinant of performance in AI data centers," Padval noted. "Eliyan has developed a distinct architecture that combines profound semiconductor knowledge with a scalable approach to meet the evolving demands of advanced AI systems." This investment positions Eliyan to play a pivotal role in overcoming the connectivity hurdles that currently impede the full realization of AI's transformative capabilities.
