Breathometer Shark Tank update: is it still in business?

Breathometer is one of the most famous deals in Shark Tank history. Founder Charles Michael Yim pitched a keychain-sized breathalyzer that plugged into a smartphone's audio jack and paired with an app showing blood alcohol content. On the Season 5 premiere, which aired September 27, 2013, Yim asked for $250,000 for 10%. Business Insider reported that he left with all five sharks: $1 million for a combined 30%, with Mark Cuban putting in $500,000 for 15% and the other four sharks splitting the remaining $500,000 for 15%. It was billed as the first time every shark joined a single deal. What happened next is documented by the Federal Trade Commission. In January 2017, Breathometer, Inc. and Yim settled FTC charges that they lacked scientific support for accuracy claims about the Breathometer Original and Breeze, which the FTC said had sales of about $5.1 million. Under the order, the company had to notify buyers and offer full refunds, and Yim is barred from making unsupported accuracy claims. Cuban has since told the Full Send podcast in 2022, as reported by CNBC, that "all of the money's gone" and "that was my biggest beating." Is Breathometer still in business? The original breathalyzer products are discontinued. We could not confirm the company's current corporate status: breathometer.com did not respond when we checked on October 14, 2026, and we found no current filing to cite. We are marking status as unknown until we can verify it against a state registry. Cuban's comments indicate the sharks' money was invested, but we could not confirm exactly how much of the $1 million was funded after taping.
