Hound Labs is a technology start-up that has created an ultra-sensitive breath analysis technology platform. We are applying our technology to solve fundamental issues with disease and drug detection. The first application of our technology, the Hound marijuana and alcohol breathalyzer, solves the public safety problem associated with marijuana legalization: how to objectively determine if someone has recently consumed marijuana. Founded in 2014, Hound Labs recently closed our Series B funding and is backed by Benchmark, Icon Ventures, and individual investors.
