Salt Lake City-based energy storage company Torus has completed a $500 million Series C funding round led by Magnetar, with participation from ICONIQ, Origin Ventures, Ridgeline Partners and Trinity Capital. Alongside the raise, Torus launched Foundry, a modular AI inference compute product that integrates power supply, energy storage, cooling, networking and compute into prefabricated units ranging from 1 to 20 megawatts per site. The company says each deployment takes approximately 12 to 16 weeks from contract signing to operation. Hydra Host is among the first batch of customers, and Torus aims to deploy more than 47,000 GPUs by the end of 2027.
