$25K/month Stagetimer App | Starter Story

A single developer built an online countdown timer that now generates $8,300 per month in revenue, serves 19,000 video producers and event organizers, and attracts 200,000 monthly visitors. The entire business was validated with a Reddit post before a single line of code was written.

The Reddit Validation Strategy

The founder did not build first and ask questions later. Before investing development time, he posted the concept of a remote-controlled countdown timer on Reddit to gauge interest. The response was strong enough that he proceeded with building a minimum viable product.

This approach reduced risk to nearly zero. The initial investment to start the business was $0.20 — essentially the cost of a domain name. By validating demand before building, the founder avoided the common trap of creating a solution nobody wants.

The Reddit community also provided early feedback that shaped the product. Users told him what features mattered most: the ability to control the timer from a separate device while the countdown displays full-screen for presenters, and reliability for live events where failure is not an option.
