US sustainable investment firm Overwatch Capital has partnered with Nautilus Data Technologies to deploy modular, AI-ready data centers powered primarily by clean energy microgrids across the US market.
The partnership will leverage Overwatch’s modular data center development and clean energy integration with Nautilus’ EcoCore infrastructure, incorporating advanced thermal management and liquid cooling technologies.
Overwatch and Nautilus plan to deliver prefabricated modular data centers that integrate critical mechanical, electrical, and plumbing systems within a single scalable framework. According to the companies, the approach will enable rapid deployment and multi-gigawatt capacity expansion in key US markets.
“Our partnership with Nautilus represents a significant step forward in modular data center design and sustainable energy solutions,” said Cole Walker, managing partner at Overwatch Capital. “By combining our expertise in modular infrastructure with Nautilus’ innovative cooling technologies, we are providing next-generation data centers that meet the evolving needs of AI-driven applications.”
The partners say the combination is designed to streamline deployment, reduce operational costs, and enhance energy efficiency for AI and hyperscale workloads.
Nautilus’ EcoCore infrastructure is a modular data center design with 2.5MW capacity. The company claims it enables efficient cooling of high-density GPU clusters without relying on traditional water consumption methods, reducing environmental impact while maintaining performance reliability.
“This partnership reflects our shared commitment to delivering sustainable infrastructure solutions tailored for AI and hyperscale computing,” said Rob Pfleging, CEO of Nautilus Data Technologies. “Our combined approach enhances operational efficiency while ensuring a lower carbon footprint.”
In March last year, Nautilus launched the EcoCore product line and announced a "multi-megawatt" data center agreement with Start Campus. Through EcoCore, Nautilus is expanding beyond colocation and becoming a supplier to other data center operators.
Overwatch Capital is an investment firm that specializes in sustainable digital infrastructure. Its primary focus is integrating clean energy solutions into data center operations. The company is headquartered in Jacksonville, Florida.
