A month ago I challenged myself to build a consumer mobile app from scratch.
As a developer, I thought the difficult part would be building it.
It wasn't.
The coding was actually the easiest part.
Now that the MVP is finished, I've realized I've entered a completely different world.
Landing pages.
ASO.
SEO.
Content marketing.
Talking to potential users.
Distribution.
Community building.
Those skills feel much harder than writing code.
I used to think:
Build something useful and people will find it.
Now I think:
You can build something great, and nobody will ever know it exists.
That's been a humbling lesson.
The app is currently in Google Play Closed Testing, so I'm using this time to learn everything I can about launching a consumer product before it goes public.
For founders who've already launched:
What was the biggest thing you underestimated?
For me, it's definitely distribution.
worth noticing: your title says "wrong problem" but everything under it is distribution — those are opposite diagnoses. if the problem is actually wrong, more ASO/SEO/ads just gets you to "no" faster; distribution only amplifies whatever's underneath it. the closed-testing phase you're in right now is the cheapest chance you'll ever get to find out WHICH of the two you have. id aim those 10 conversations (like the other commenter said) squarely at "is this even the right problem for these people", not at "how do i get users" — before sinking another month into acquisition channels.
One thing I'd question is whether distribution is always the problem.
Sometimes it is. But sometimes it's that the product solves a problem people only recognize after they already have the solution. In those cases, marketing has to educate before it can sell, which makes every acquisition channel feel harder. Figuring out which of those you're dealing with changes almost every decision that follows.
Distribution is the one I underestimated the most too. Built a solid product, assumed "if you build it they will come." Reality: spent weeks on SEO, landing pages, even ran ads — got a handful of users. The thing that actually moved the needle was manual outreach: finding 10 people who fit the exact profile and talking to them directly. It doesn't scale, but it teaches you more about your market than any landing page A/B test ever could.
