About Culer

Founded in 2006 and headquartered in Columbus, OH, Culer operated in the B2C electronics industry as a manufacturer of personal cooling devices. The firm raised approximately $12.2 million over several funding rounds, including a Series A in 2011 and a Series B in 2013, to support its operations.

The company's core business was the production and sale of flash-evaporative air coolers. These devices were engineered for personal and portable cooling, targeting consumers who needed a directed stream of cool air in specific locations, both indoors and outdoors. The business model centered on selling these physical hardware products to individuals.

Culer's main product line, including the Culer SOLO, utilized a patented Flow-Blurring™ technology. This system atomized potable water to create a fine mist, which would then evaporate to naturally lower the temperature of the airflow, producing a cool breeze without chemical refrigerants. A key differentiator was that the products did not use pads that require frequent cleaning, maintenance, or replacement. The coolers were designed to be lightweight and energy-efficient, operating on a low-voltage 12V system and consuming as little as 35 watts of power. Features included a one-gallon water reservoir providing up to 10 hours of use, multiple fan speeds, and an adjustable port to direct the cool air. PitchBook data indicates the company is now out of business.
