Bumble is a location-based social application that facilitates communication between interested users. In heterosexual matches, only female users can make the first contact with matched male users, while in same-sex matches either person can send a message first.
Users can sign up using their phone number or Facebook profile, and have options of searching for romantic matches or, in “BFF mode”, friends. Bumble Bizz facilitates business communications. Bumble was founded by Whitney Wolfe Herd shortly after she left Tinder, a dating app she co-founded, due to growing tensions with other company executives. Wolfe Herd has described Bumble as a “feminist dating app”. As of September 2019, with a monthly user base of 5 million, Bumble is the second-most popular dating app in the U.S. after Tinder. According to a June 2016 survey, 46.2% of its users are female. According to Forbes, the company is valued at more than $1 billion, and the company reports having over 55 million users in 150 countries.
