What they did

Noticed that under height videos on TikTok, people post their age, height and parents' heights, wanting a prediction. Made reply-to-comment videos predicting those commenters' heights. Inbound DMs requesting predictions served as proof that people care.

MichaelSo that's when I began like building it, and then I remember like after 2 days of launching it, I already had the first sale. And that was also a huge amount of validation for me, because I didn't even get that many views, and I was like, "Wow, people really want this."

MichaelAnd then the second thing is that on TikTok, if you just look at any sort of height video in general, I would see people saying like, "Oh, I am 6 ft, I'm 15, my mom's this height, my dad's this height."

People like really care about this like height prediction thing. There's some problems that you can really just see, and you're like, "Wow, this is an actual painful problem."

MichaelYeah, I think the Maslow's hierarchy of needs is a really good framework for like, what do people like want. If you think about your app idea, ideally, it can fit into like one of these categories. The more like things it hits, the better. So for example, for me, the the height prediction app, one, it hits the esteem part, because people want to know that they're going to be tall because they want, you know, respect from other people.
