Dallas billionaire Mark Cuban is in the news lately for his drug company startup, Cost Plus Drugs. Over the years Cuban was also on a show called Shark Tank, where would-be inventors and small business owners pitched their business ideas, competing for an investment.
While being interviewed for the “Full Send” podcast Mr. Cuban revealed his “worst” investment that he made on Shark Tank. An entrepreneur named Charles Yim appeared on the show to demonstrate his Breathometer, a smartphone breathalyzer app he claimed could test blood alcohol levels accurately.
