## About

Based in California, US, founded in 2022, Liitto Technology, Inc., d.b.a. Rune, develops modular direct-current data centers for renewable-energy sites. The company was co-founded by William Layden (CEO as of 2026) and Varun Palivela. In September 2026, Rune raised USD 40 million in series A funding led by Spark Capital, with participation from Activate Capital, Committed Capital, Timeless Partners, Inc., and Logos Fund, Union Square Ventures, Vestas and Lowercarbon Capital.

Rune develops Renewable Energy Linked Interruptible Compute (RELIC), modular direct-current data centers installed behind the inverter at solar and wind plants. The systems use surplus or curtailed electricity for AI training, simulations, data processing and lower-carbon bitcoin computing, with software controls that respond to available generation.

Rune performs computational workloads using surplus renewable electricity, while its installations enable renewable-power operators to increase electricity sales that would otherwise be lost through curtailment, clipping or outages.

The company plans to use the Sep 2026 funding to expand its power partnerships and compute customer base.
