if you're an app the idea that someone's going to see your product without prompting them first with an ad is insane no one goes to the app store and just browses around you go to amazon and you browse around you don't do that with the app store you only go to the app store after you've clicked an ad
Nobody Browses the App Store — Brand Marketing Doesn't Work Without Direct-Response Follow-Up
Eric Seufert's rebuttal to the brand marketing escape hatch: app users do not proactively browse the App Store the way they browse Amazon or a grocery store. Brand advertising is only valid for apps if it elevates the click-through rate on a subsequent direct-response ad — it cannot substitute for it. The magical thinking that brand awareness will drive unprompted App Store visits is non-falsifiable and lethal to growth budgets.
I think people underestimate the knowledge they already have. If you have deep domain knowledge you probably have like tons of ideas already on what to build, and you probably have a winning idea already that you could just prompt your way and start building.
Leverage the domain knowledge you already have to find winning ideas
Polus built Creator Hunter because he was already pursuing creator-led services and felt the pain of finding influencers himself. His domain knowledge wasn't technical — it was operational and contextual. The barrier to building is no longer code; it's recognizing that the problems you've solved manually in your own work are the highest-signal product ideas you'll ever have.
There's a play for whatever you're stuck on.
