Rune colocates compute with solar generation so AI workloads use power that would otherwise go unused when utilities curtail panel output. Proximity removes long-haul transmission hardware and the DC to AC to DC conversions of a grid-connected data center.
The modular design supports fast deployment, with customers able to start AI workloads within weeks rather than the years a standard data center requires. The Series A syndicate of Spark Capital, Union Square Ventures, and Lowercarbon gives the company venture backing across AI infrastructure and climate technology.
Rune sells compute capacity as a service to AI laboratories, cloud providers, and large-scale computing customers. Deployments sit on solar generation sites, with the first installation at a 200-megawatt facility in Texas and reported plans to expand to wind farms.
The company operates from 480 Ellis Street in Mountain View, California, under the legal name Liitto Technology, Inc. Founders William Layden and Varun Palivela lead as chief executive and chief technology officer.
RELIC, short for Renewable Energy Linked Intelligent Compute, is a modular computing system designed for AI workloads and installed on the premises of solar farms. Each module ships with up to 1,024 graphics cards plus cooling equipment and custom power management components.
The system runs servers directly on DC power from nearby photovoltaic cells, removing long-haul transmission lines and transformers. Rune states that RELIC cuts auxiliary infrastructure cost by 85 percent and can be set up in about one hour.
