$25K/month Stagetimer app | Starter Story

The episode opens with a striking detail: a simple online countdown timer called Stagetimer.io generates $25,000 per month in revenue, run entirely by one person who validated the idea on Reddit. The founder built a niche tool that event organizers and video producers pay $180 per year for, and the business now attracts 200,000 monthly visitors to a website that does nothing but display timers.

The Reddit validation strategy

The founder did not build first and ask questions later. Instead, he posted the concept on Reddit before writing any code, describing the problem he wanted to solve: presenters need a countdown timer they can see on their own screen while someone else controls it from another device. The Reddit response told him he was onto something real. Event organizers, video producers, and conference runners immediately recognized the pain point. This upfront validation meant he could build with confidence that at least some people would pay. The approach also gave him early users who felt invested in the product's success because they had helped shape it.
