AttoTude announced that it has raised $52 million in Series C funding to accelerate the commercialization of its interconnect technology designed for hyperscale and AI infrastructure.
The financing round was led by The Westly Group and included new strategic investors Keysight Technologies, Allegis Capital, and DNX. Existing investors Sutter Hill Ventures, Mayfield, Canaan, and Wing Venture Capital also participated. With the latest financing, AttoTude’s total funding has reached $143 million.
Headquartered in Menlo Park, California, AttoTude is developing a new class of interconnect technology based on what it describes as an “ASIC over Dielectric” architecture. The platform enables electrical signals to travel over low-loss dielectric waveguides and is intended to address the growing connectivity requirements of large-scale AI clusters.
According to the company, its technology is designed to provide high-density, energy-efficient connectivity for per-lane data rates of 200G, 400G, and 800G. AttoTude said the architecture offers an alternative to conventional copper interconnects while avoiding the power consumption, cost, and complexity challenges associated with optical technologies.
The company believes the approach can help solve a critical infrastructure challenge facing hyperscale operators and AI data centers as computing workloads continue to expand. The platform is designed to support scalable mid-range connectivity while providing a path toward future high-speed interfaces.
AttoTude said it plans to showcase its first product demonstrations later this year as it transitions its technology from research and development into commercialization.
The Series C proceeds will be used to advance product development, build initial prototypes, and establish a scalable supply chain. The company said the new capital positions it to pursue broad deployment opportunities with leading hyperscale and AI infrastructure providers.
The Westly Group Managing Partner Steve Westly said AttoTude has generated strong customer interest and demonstrated industry-leading performance while reducing energy consumption for AI clusters. Keysight Technologies also highlighted the importance of emerging interconnect architectures as AI infrastructure scales.
Founded by Dave Welch, a co-founder of Infinera, and Joy Laskar, a serial entrepreneur and former professor at the Georgia Institute of Technology, AttoTude focuses on next-generation connectivity technologies for artificial intelligence and hyperscale computing environments.
