Josh Claman is the Executive Chairman and Founding CEO of Accelsius, a global leader in two-phase direct-to-chip liquid cooling technology for AI data centers. He co-founded Accelsius in 2022 to address one of the sector’s most pressing challenges: the enormous energy and water demands placed on communities by AI infrastructure. Under his leadership, the company developed NeuCool, a closed-loop, waterless cooling platform engineered for the thermal demands of next-generation AI chips—delivering up to 50% energy savings compared to traditional air cooling while eliminating facility dependence on local water supplies.
Claman brings more than 30 years of global technology leadership to the role. He previously served as Vice President of Public and Large Enterprise for the Americas at Dell Technologies, overseeing multi-billion dollar business units across North and South America, and as General Manager of Dell UK—part of a career that spanned five continents and included senior roles at both AT&T and NCR. He later served as President of ReachLocal, Chief Business Officer at 3D printing pioneer Stratasys, and Chief Executive Officer of digital health company Rimidi.
Claman earned a BA with High Distinction in History and Government from the University of Illinois Urbana-Champaign and an MBA from the Darla Moore School of Business at the University of South Carolina. He writes and speaks frequently on the intersection of technology, energy, and public policy, and has addressed data center sustainability at forums across North America and Europe. He believes the industry’s long-term license to operate depends as much on community trust as on technical performance.
