On dating app Bumble, the ladies are required to make the first move. Once those women make a match, the app gives them 24 hours to reach out and start a conversation. The company launched at the end of 2014, gaining more than three million users. Now, Bumble is heading into the "friend zone" with Bumble BFF. The app uses its algorithm to help people find friendship. Founder and CEO Whitney Wolfe, who was a co-founder of Tinder, joins “CBS This Morning” to discuss the new venture.
