Build just the viral feature as a TestFlight and let creators film it

What they did

Find viral videos with SpyTok, build a TestFlight with only the feature that looks good on camera, hand it to a creator to film (two phones: one recording, one showing the app). If videos go viral while the app isn't live yet, demand is validated.

Steve Young… perfect. And then if I can't get downloads, then I don't really try to invest in the monetization or building out the features. But then forcing the start trial and the if the trial-to-paid is not there, then I know I have a product problem, not a a channel problem. So at least the the market wants this product, market channel-market fit, but my product didn't live up to the promise. So now I know I have to build a finish building the product.

Joseph ChoiYeah. One cool thing I would add to this, also, it's like, yeah, you can use SpyTok to find viral videos, and then you can even make a TestFlight. So I'm working with a client right now where we're just building a TestFlight that has only the viral feature, and then we give that to the creator. So then the creator just can make viral videos with just the TestFlight. And then those people that watch, if it goes viral, then people will, you know, go and like try to download the app, it won't exist. But you still got that validation of like, "Wow, this People thought there was an app, it got tons of views."
