$25K/month Stagetimer app | Starter Story

StageTimer.io is an online countdown timer that generates $8,300 per month in revenue, run by a single founder with zero startup costs. The business validated its idea on Reddit and now serves 19,000 video producers and event organizers, including staff at major companies. The product is a remote-controlled countdown timer: presenters see a full-screen timer while someone else controls it from another device. The site does 200,000 monthly visits, and the founder charges $180 per year (about $16 per month) with usage-based pricing that increases when additional team members are added.

The Reddit validation strategy

The founder did not build the product first and then look for customers. Instead, they posted the concept on Reddit to gauge demand before writing any code. The response was immediate and specific: event organizers and video producers described exactly the pain point of needing a timer that could be controlled remotely from a separate device. This gave the founder a clear signal that the problem was real and that people would pay for a solution.
