You don't need a million-dollar idea to build a productYou need a problem that annoys you enough to fix it.

That's exactly what happened this week when I built a ringtone download page.

Let me tell you a story and what it taught me about finding business opportunities.

I was scrolling TikTok and came across a viral German song called "Du bist gut genug" — "you are good enough" in English. The tune was stuck in my head within a minute.

So I did what everyone does — searched for where to download it.

Found a site. Got hit with a wall of ads and cookie popups before I could even see the download button. When I finally got to the audio, the quality was noticeably worse than the original video.

I know what I want, so I didn't settle. I pulled the video itself, converted it to mp3 myself, and set it as my ringtone.

A couple of days later I went back to that same TikTok — it had racked up millions of views.

On a whim, I dropped a comment: "Should I drop the link of where to download this?"

Within minutes: "yes please."

That was it. I paused what I was working on — figured it'd take a few minutes — and built a small page where people could preview the tune and download it properly, no ads, no clutter.

But that "yes please" changed how I built it.

This wasn't a ghost project anymore — someone actually wanted it, and that was all I needed.

So I built the page around that: the person who said yes please is credited right on the page, because this whole thing exists because of them.

And underneath,

I added a short line about who I am, with a link to my work and my site.

Here's the thinking — whoever sees themselves credited on that page isn't just going to download the tune and leave. It leaves an impression. They'll show a friend. And the takeaway isn't just "nice ringtone" — it's "this person is a developer, and a good one." That's not an accident. That's marketing, just done quietly.

I also added a small twist: before the download starts, you get asked to leave a like and (optionally) a quick comment. Partly for feedback, partly to actually see if anyone cared.

In a day: 17 likes.

Not a huge number. But it told me something worth remembering:

To build something people actually want, you usually have to be the person who wants it first.

If you're annoyed by something, stuck on something, or wishing a thing was just a little easier — that discomfort is usually pointing at a real problem. And real problems are where business opportunities live.

You don't need a market study to start. You need to pay attention to your own friction.

So — sit with your own problem for a bit. Find the thing that's mildly annoying you right now. Then come talk to me, and if it's something software or a mobile app can solve, I'll help you build the solution.
