In their words
This Stupidly Simple App Makes $100K/Month
Pat WallsLet's move a little bit to the idea, cuz this idea is crazy, it's almost preposterous. This height predictor app, but it's obviously crushing it. So let's talk about, how did you find this idea, and then second, how did you know it was a good idea and worth, like, throwing everything into?
MichaelI first saw this idea when I was looking on website, literally websites like acquire.com, cuz I was like, "I don't know any good ideas. I want to find a validated idea." And I saw an app that's pretty similar to this, for sale for around $20,000. And then I thought to myself like, "Wait, actually, this is definitely a real problem." Because I was, when I was 13 years old, I was looking up like height calculator on Google or something.
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."
Pat WallsOn that note, what would be your advice for other people who are watching this right now, who want to find an app that's crushing it like yours? What would be your advice for those people watching right now?
MichaelI would say there's just like so many more ideas that can be successful that people thought. Like, I feel like a lot of people they see that some idea is already existing, and then they're just like, "Oh, I'm out." You know, like, "I'm not going to build this anymore." Whereas even in today's age, like there's still calorie trackers doing 30k a month when you have Cal AI. Like that does not make sense to me at all. And I feel like just seeing that sort of phenomenon happening, it just proves that no idea like has already been done before, and you can always try to do the same idea someone else did and still make it successful with your own tweaks and things like that.
MichaelThe other thing, you want to make something that really hits with people's needs. I had my TikTok, and I would have like 10, 20 DMs a day of people requesting their height to be predicted. 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."
