Tinder is a location-based social search service application (using Facebook) that facilitates communication between mutually interested users, allowing matched users to chat.
Rad and Mateen had known each other since they were fourteen.
They later attended USC together and entered the Internet entrepreneurship field.
Rad has stated that the impetus for the app was his observation that "no matter who you are, you feel more comfortable approaching somebody if you know they want you to approach them." He believed that a "double opt-in" system could be created to potentially alleviate that stress.
Rad has also stated that Tinder filled a gap for social sites for meeting strangers, rather than connecting with people a user already knows.
The selections a user makes are not known to other users, unless two individuals swipe right on each other's profiles.
