About ColdWatt

ColdWatt Inc. operated as a developer and manufacturer of power converters, targeting the computing, telecommunications, networking, and storage sectors. Founded in 2004 and headquartered in Austin, Texas, the company focused on creating highly efficient power supplies. The firm's strategy was to commercialize power conversion technologies initially developed at Rockwell Scientific Company, which had conducted related research for the U.S. Navy.

The company's offerings included AC-DC and DC-DC power converters designed to be more efficient, generate less heat, and occupy less space than conventional power conversion equipment. ColdWatt's first-generation server power supplies and eighth-brick DC-DC telecom power supplies were marketed on the claim of dissipating over 50% less heat than competing products at the time. The primary clients were Original Equipment Manufacturers (OEMs), IT managers, and systems designers. The business model revolved around the design, development, and sale of these advanced power supply units.

The company was initially known as GTI Power Systems and was seeded by investment firm GTI Ventures. It secured significant venture capital, raising a total of $31.6M across multiple funding rounds. A Series A round in March 2005 brought in $15.5 million, co-led by Austin Ventures and Matrix Partners. This was followed by a second round of $16 million, led by RRE Ventures, to fund further product development and sales expansion. The company was led by CEO Dan Artusi, a veteran executive from Motorola and Silicon Laboratories Inc. On September 8, 2008, ColdWatt was acquired by Flex, a BPO/Outsourcing Services provider, marking its final milestone as an independent entity.
