Photograph a stamp, get an AI valuation plus its history — an ultra-narrow identifier app that siphons traffic straight from App Store search
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Max is the subject of this Starter Story Build episode, and introduces himself as having 'built a mobile app portfolio of almost 40 mobile apps' — the vast majority of them made after hours around a nine-to-five, with this year being the first he's gone full-time indie. The host keeps returning to the same point: he ships at a rate of roughly one app a week, and the portfolio together does about $36,000/mo. Note that this is a portfolio figure, not a single product — Stamp Identifier, built live in this episode, is brand new and has no revenue at all. So its value isn't in 'how much can this stamp app make', it's that it demonstrates Max's entire replicable production line end to end: from a single keyword to a shippable subscription identifier app in 17 minutes. For anyone copying this, the real asset is the process itself; Stamp Identifier is just one live sample of it.

Stamp Identifier was built live in this episode and has no data yet, so its individual revenue is treated as potential rather than fabricated. All revenue figures are founder-reported or estimated by the video's creator, and are unaudited.
