Entrepreneurs & Investors:


Founded in 2015, Submer provides best-in-class technology that enables data centres around the world to leverage the power of immersion cooling for HPC, hyperscale, data centres, Edge, AI, DL and blockchain applications.

Air-cooled data centres today consume 10% of global electricity output and will emit 2.75% of GHG emissions by 2025 (surpassing the airline sector) and potentially also become a large-scale water consumer. Liquid immersion cooling is the next generation of more sustainable data centre cooling technologies. Submer’s innovative, patented technology uses modular tanks filled with a biodegradable electrically non-conductive liquid to cool data centre server units. The technology uses 50% less energy, 99% less water and 85% less real estate than traditional cooling, and future-proofs customers against evolving emissions regulations.

“We are incredibly excited about joining Daniel, Pol and the Submer team on their journey to make data centres and computing environmentally sustainable. We believe that Submer’s core next generation cooling technology, the entrepreneurial drive and long-term vision for “data centres that make sense” and the strong ecosystem partnerships developed to-date will catalyse main-stream adoption for immersion cooling.” Andreea Constantinescu, Partner at Planet First Partners.

“The partnership with Submer lies in the sweet spot of our investment mandate: the intersection of strong sustainability credentials with innovative technology and consumer preferences. We believe that Submer’s immersion cooling pods will play a key role in making data centres sustainable, assuring the future growth of the data-enabled economy.” Frédéric de Mévius, Managing Partner of Planet First Partners.
