AttoTude is developing a next-generation interconnect platform that combines advanced ASIC signal generation with low-loss dielectric waveguides to enable per-lane data rates of 200G, 400G, and 800G. The company positions its ASIC over Dielectric architecture as a mid-range connectivity solution that aims to overcome limitations of conventional copper interconnects while avoiding some cost, power, and complexity challenges associated with optical technologies. AttoTude plans to transition its technology from discovery to product development, with first product demonstrations slated for this fall and work underway to build prototypes and a scalable supply chain. Financially, the company has raised $52 million in Series C funding, bringing its total funding to $143 million. AttoTude was founded by Dave Welch and Joy Laskar and is headquartered in Menlo Park, California.
