Stephen has shipped hit app after hit app, and he's publishing his four-step idea-validation framework. Posted is doing $90K/mo right now; his last one, PuffCount, hit $44K/mo before he sold it. The core of the method: marketing is 90% of the outcome.

Stephen (YouTube/IG: Stephen Builds) is a serial app founder with two exits behind him. His previous product, PuffCount (quit vaping by tracking your puffs), reached $44K/mo before he sold it; his current product, Posted, is crossing $90K/mo. The bulk of this video is his idea-selection and validation framework rather than a deep teardown of any single product.
