Claros, a startup that minimizes energy waste at data centers, has secured a $30 million seed round from General Catalyst and Red Cell Partners. The company plans to commercialize advanced voltage regulators that provide power directly to servers' main processors. This model reduces "heat conversion loss" and allows operators to increase efficiency by controlling voltage. It has already fabricated three of these "integrated voltage regulators" (IVRs) and is working with manufacturers including Samsung. The other product is a modular data center that can run solely on direct current power.
