Submer, a global leader in immersion cooling solutions, has announced the launch of a new business unit, InferX, dedicated to providing sovereign AI cloud services. The move signals a significant expansion for the company from a specialist cooling provider into a full-stack AI infrastructure operator.
According to the company, InferX aims to deliver a "faster, denser, and greener AI cloud" by leveraging a dual-plane strategy. This approach will connect core data centers, which will handle large-scale AI model training and hosting within high-density GPU clusters, with Edge AI infrastructure. The Edge component is designed to provide real-time inference capabilities closer to end-users through telecommunications and regional networks.
"AI is becoming a critical utility, and it deserves the same reliable, efficient, and sovereign infrastructure as energy," said Daniel Pope, founder of both InferX and Submer. "InferX has been created to provide that foundation – building an AI cloud platform that focuses on real AI use-case enablement."
The new division will combine Submer's established expertise in single-phase immersion cooling with advanced AI operations and delivery capabilities. The company clarified that its InferX unit is not related to the US-based serverless inference platform of the same name.
While specific details on planned data center locations or deployments were not disclosed, InferX's website indicates it will utilize a vertically-integrated data center design featuring liquid-cooled GPU clusters.
This launch continues Submer's strategic evolution. Earlier this year, the company, founded in 2015 by Daniel Pope and Pol Valls Soler, announced its intent to move into building complete data centers, with its first 56MW facility planned for Barcelona, Spain.
Submer has also been active in forming large-scale partnerships, recently signing a Memorandum of Understanding with the government of Madhya Pradesh, India, to jointly develop up to 1GW of liquid-cooled AI data centers.
