What they did
Started with a scrappy app that did not fully do what the marketing claimed, sold it through strong distribution, then built out the underlying tech. Priced at $29.99/year.
What happened
Host says Cal AI is now 'a fantastic app' after building out the tech.
In their words
Sub Club by RevenueCat · Buying vs. Building: Scaling Beyond a Single App — Josh Peleg, BlueThrone“But to their credit, they have since actually built out that tech. So, to your point, maybe you build a painted door app where you prove out that people are willing to pay for this and then you go build it.”
