Nautilus Data Technologies Secures Series B Funding Led by Pangaea Ventures to Scale Liquid Cooling Solutions

Nautilus Data Technologies Secures Series B Funding Led by Pangaea Ventures to Scale Liquid Cooling Solutions January 28, 2026 Nautilus Data Technologies, a provider of modular data center and liquid cooling infrastructure, has closed a significant Series B funding round led by the Canadian venture capital firm Pangaea Ventures. The investment arrives at a critical juncture for the data center industry, which is grappling with unprecedented power and cooling demands driven by the explosive growth of artificial intelligence and high-performance computing workloads. The company announced the financing this week, though the exact amount was not disclosed. According to Nautilus, the capital will be deployed to scale manufacturing and order fulfillment capabilities, expand global sales, marketing, and channel partnerships, and accelerate ongoing product innovation. This strategic move underscores the intensifying market focus on efficient thermal management solutions as traditional air cooling reaches its limits. "This funding comes at a pivotal moment not just for Nautilus, but for the industry," said Rob Pfleging, CEO of Nautilus Data Technologies. "The market is already experiencing expansive growth, driven by AI and high-performance computing. This investment enables us to further reduce lead times, expand manufacturing capacity globally, and scale to meet ongoing demand." Originally known for developing its own floating, river-cooled data center barge in Stockton, California, Nautilus has pivoted its business model. The company now supplies its proprietary liquid cooling technology and modular data center systems, marketed under the EcoCore product line launched in 2024, to other developers. Its cooling equipment is slated for deployment at major projects, including the Start Campus site in Sines, Portugal. Pangaea Ventures, a firm focused on hard tech ventures since its founding in 2000, expressed strong confidence in Nautilus's trajectory. "Rob Pfleging and the Nautilus team have the technical depth and execution discipline needed to set the new standard for AI data center build-outs," said Chris Erickson, founding general partner of Pangaea Ventures. "Nautilus’s rapid, modular liquid cooling solutions are arriving at exactly the right time to redefine what efficient, sustainable capacity expansion looks like." The funding round signals growing investor appetite for infrastructure technologies that address the core constraints of modern data center expansion. As power densities continue to climb, Nautilus's success in securing venture backing highlights the sector's urgent shift toward liquid cooling as a fundamental enabling technology for future compute infrastructure.
