Tinder is a location-based social search mobile app that allows users to like or dislike other users, and allows users to chat if both parties liked each other in the app. Tinder was launched in 2012 within startup incubator Hatch Labs, and both attended the University of Southern California and became online entrepreneurs at the same time. The app is often used as a dating site. Tinder became the first new online dating service to claim a spot as one of the web's top five utilized services in about 10 years. As of 2016, Sean Rad is the company's CEO. As of 2018, Tinder is available in over 190 countries and is available in 40 languages.
