The saying goes that love is stronger than hate, but a new dating app is flipping that idea upside down. Hater is a new app that matches users based on the things they mutually dislike.

Brendan Alper, Founder and CEO of Hater, explains how the app app works. He says even if you don't meet a special someone, it's fun to use. Alper says they already have 800,000 users since launching on Valentine's Day this year.

Alper also shares what it was like to land a $200,000 investment from billionaire Mark Cuban on ABC's "Shark Tank." The company plans to use the investment to expand, especially in New York City. Alper says Cuban is so into the company that he even created his own account, just for fun.
