Eliyan Achieves Unicorn Status with $145 Million Series C to Advance Electro-optical Interconnects for AI Infrastructure

Eliyan, a leader in foundational connectivity technologies enabling next-generation AI compute, memory, and networking systems, led by Ramin Farjadrad, Patrick Soheili, and Syrus Ziai, has announced it has completed its Series C with a total of $145 million at a $1 billion valuation. The oversubscribed round was led by Seligman Ventures, with participation from additional new and existing investors, including two new strategic investors: Cisco Investments and Lumentum. As part of the financing, veteran technology investor and operator Umesh Padval, Managing Partner of Seligman Ventures, will join Eliyan’s Board of Directors.

Expanding AI Infrastructure Through Optical Connectivity.

The funding will support Eliyan's expansion into the growing electro-optical interconnect market, as demand rises for higher-performance AI infrastructure.

The investment reflects increasing industry confidence in Eliyan's approach to developing advanced electrical and optical connectivity solutions designed to address the growing requirements of AI systems, including higher bandwidth, improved reliability, and greater power efficiency.

The company is focused on commercializing a range of interconnect architectures that enable next-generation AI infrastructure to scale more effectively.

Building the Connectivity Layer for Next-Generation AI Systems.

Eliyan is developing advanced interconnect technologies designed to address the growing connectivity challenges of next-generation AI infrastructure.

The company's die-to-die, chip-to-chip, and rack-to-rack solutions support increasingly complex architectures, including advanced chiplet integration, multi-package systems, memory expansion, and high-bandwidth infrastructure networks.

As AI systems scale from individual accelerators to large-scale clusters, factors such as interconnect bandwidth, memory capacity, and power efficiency are becoming critical constraints on performance. Eliyan's technology is focused on enabling more scalable and efficient AI computing architectures.

Developing the Next Generation of AI Interconnect Technology.

Eliyan is developing an electro-optical interconnect platform designed to address the growing connectivity, memory, and power challenges of large-scale AI systems.

The company's NuLink™ PHYs and NuGear™ chiplet technologies provide scalable connectivity solutions across compute and memory architectures, while its expansion into optical interconnects extends its capabilities toward future AI infrastructure needs. The platform is designed to support the industry's shift toward more distributed, heterogeneous, and bandwidth-intensive computing systems.

The new funding will support further development of Eliyan's interconnect technologies, expansion of ecosystem partnerships, and manufacturing scale-up. The investment follows growing commercial engagement with hyperscale, AI accelerator, memory, and infrastructure companies evaluating or deploying the company's solutions.

Advancing the Future of AI Infrastructure Connectivity.

Eliyan is focused on addressing the growing connectivity challenges emerging as AI infrastructure becomes more complex and interconnected. The company believes traditional approaches to system architecture are reaching their limits as compute, memory, packaging, and networking requirements continue to scale. Eliyan's interconnect technologies are designed to support the next generation of AI systems by improving data movement, efficiency, and scalability. The latest financing will help accelerate product development, expand customer adoption, and strengthen ecosystem partnerships as the company advances its AI infrastructure platform.

Strategic Backing for AI Interconnect Innovation.

Seligman Ventures highlighted the growing importance of high-speed interconnect technologies as AI systems scale across increasingly complex computing architectures. The firm believes efficient electrical and optical connectivity between compute and memory will become a critical factor in the performance of future AI data centers. Eliyan's differentiated architecture, semiconductor expertise, extensive patent portfolio, and support from strategic industry investors were cited as key factors behind the investment. Seligman Ventures will support Eliyan's growth as the company expands its technology platform and works toward broader adoption across next-generation AI infrastructure markets.
