KHN Solutions created both the BACtrack and BluFire brands. I’ve categorized work for each separately, but it was actually work for just one company.
BluFire helped pioneer the consumer market for advanced health and safety devices. BluFire first offered breathalyzers online in 2001 and positioned them as an entertaining safety device that should be used by everyone consuming alcohol. Since then the company has expanded into body fat scales, digital thermometers, pedometers, and other consumer products.
