No. 4: Tinder
Released back in 2012, Tinder is basically a matchmaking app, which links people together based on their basic information and social graphs. But unlike other services of this kind, Tinder does things a little bit differently. The service only allows the two users to engage with each other only after both parties have shown an interest in the other. According to the New York Times, Tinder is being downloaded by Android and iOS users approximately 20,000 times a day. With figures like these, saying that Tinder is a fast rising startup is an understatement.
