KEY QUOTES:

“AI infrastructure is undergoing one of the largest architectural transitions in computing history. As compute, memory, packaging, and networking become increasingly interconnected, traditional approaches to system connectivity are reaching their limits. Eliyan was founded to address these challenges at the architectural level.”

Ramin Farjadrad, CEO and Co-Founder, Eliyan

“We are thrilled to partner with repeat founders Ramin, Patrick, and Syrus as they build a leader in high-speed interconnect technology for AI infrastructure. As AI systems continue to scale, efficient electrical and optical interconnects that enable future scale-up and scale-out networks between compute and memory are becoming the performance-defining technologies of modern AI data centers.”
