Two-phase direct-to-chip liquid cooling firm Accelsius has announced a change of chief executive officer.
The company this week announced that founding CEO Josh Claman will assume the role of executive chairman, where he will focus on strategic partnerships, customer relationships, and the company’s capital strategy.
John Hewitt, an Accelsius board member, will be appointed CEO. The leadership transition is effective July 6.
“Founding Accelsius and helping establish two-phase liquid cooling as the foundation for AI infrastructure has been the most rewarding chapter of my career,” said Claman. “We have assembled a remarkable team, the science is proven, the customer momentum is real, and the platform is ready to scale. John has been a trusted partner on our board, and his operating record in this exact industry is the right fit for what comes next. As executive chairman, I will remain fully devoted to Accelsius, working alongside John on the strategic partnerships, customer relationships, and capital strategy that will define our next chapter.”
