San Ramon, CA — Nautilus Data Technologies, a leader in facility-scale liquid cooling, announced today it has closed a Series B financing round, led by Pangaea Ventures. The new capital will be used to support scaling manufacturing and order fulfillment, expand sales, marketing, and channel partnerships, and accelerate ongoing product innovation. The funding will also advance Nautilus’ expansion across the United States and Europe and support the company’s pursuit of NVIDIA DA-12515 certification, further strengthening its position as a trusted provider of AI-ready data center infrastructure.

“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.”

As part of the agreement, Chris Erickson, founding General Partner of Pangaea Ventures, has joined Nautilus’ Board of Directors. Erickson brings more than 25 years of experience and currently serves on the boards of multiple portfolio companies.
