Data center firm Nautilus Data Technologies has secured new funding.

The company this week announced that it has closed a Series B financing round, led by Pangaea Ventures. The size of the investment wasn’t shared.

Nautilus said the capital will be used to support scaling manufacturing and order fulfillment, expanding sales, marketing, and channel partnerships, and accelerate ongoing product innovation.

“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 a data center developer, Nautilus has been pivoting to providing infrastructure for other developers. In 2024, the company launched its EcoCore product line featuring modular data center systems and cooling equipment.

The company’s cooling tech was originally deployed at its barge-based facility in California, which uses river-cooling. Launched in 2021, that facility was put up for sale in 2024. Nautilus has also dropped plans for a river-cooled facility in Maine.

A provider of infrastructure, Nautilus is providing cooling systems to the Start Campus site in Sines, Portugal.

Founded in 2000, Pangaea Ventures is a Canadian venture capital firm focused on “high-potential hard tech ventures.”

The firm has previously invested in various chemical, energy, carbon capture, agriculture, pharma, and healthcare companies.

“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’ rapid, modular liquid cooling solutions are arriving at exactly the right time to redefine what efficient, sustainable capacity expansion looks like. This is precisely the kind of transformative hard tech innovation that Pangaea looks to back.”
