While some business ventures shown on "Shark Tank" continue to achieve success after the show, such as former NFL player Chris Gronkowski's Ice Shaker, others aren't as lucky. If one were to look up the Hater app on Google Play or the App Store, one would have some issues downloading it. That's because it's no longer in existence. Plus, the official Twitter account @LoveThroughHate hasn't been active since April 2018.

So what went wrong? When Brendan Alper launched Hater, there was no premium subscription option (via CNBC), which meant there was no revenue coming in from users. Though he was slated to roll out this feature at some point, it might not have helped Hater achieve longevity in the dating app world.

On Reddit, a number of people expressed their confusion as to why the sharks were so captivated by Alper's concept. Many felt that first dates based on mutual hatred would be rather negative. U/camouflage365 said, "You should be focusing on the things you DO like because those are the things you're obviously going to be devoting time and energy on." Others tried out Hater but didn't enjoy the experience. They found it to keep crashing and have a limited number of users in their immediate area.

Still, it seems that Alper is moving past his failed Hater app and giving the digital world another try. According to his Twitter, Alper is now operating Everbloom. Its mission is "to help creators fund their passion by launching their own NFT drops."

Hopefully, Alper's new endeavor, which has a more positive message behind it, pans out better than the first.
