A remote-controlled countdown timer for speakers and show callers
2 founders, no employees
A countdown timer, sold to people for whom running over is an incident — a TED talk overrunning is a business failure; an egg overcooking is just a bad egg.
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Stagetimer is stagetimer.io — a remotely controlled full-screen countdown timer: one device displays a full-screen countdown for the speaker on stage, while you control it from a browser on a different device, adding or subtracting time, pausing, and jumping between segments. The video's host reacts the way most people do at first: how is this different from setting a 45-minute timer on my iPhone? Why does it make money? The answer is the cost of getting the timing wrong. If your egg timer doesn't go off, the egg is ruined — not a big deal, and you'd never pay for that. But if it's a TED talk — and TED is a company, with thousands of people in the room and hundreds of thousands watching online — a speaker running over wrecks the live experience and hurts the online distribution. That's a business incident. The moment you put the most mundane function imaginable, timing, into a commercial context where errors are costly, it goes from a free toy to a professional necessity. When Starter Story interviewed founder Lucas in 2023, the business was doing about $8,000/mo; in this video it's at $25,000/mo, with two founders and zero employees.
The first customers came from one Reddit post nobody would call a success. It went into r/commercialav, the commercial audio-video subreddit with about 31,000 members, and collected 60 upvotes and 34 comments.

Data credibility: The main Starter Story channel interviewed founder Lucas: about $8,000/mo back in 2023, up to $25,000/mo at the time of this video, with two founders and zero employees. Numbers are as relayed in the video. All revenue figures are founder-reported or estimated by the video creator — unaudited.
The first paid account in a product like this converts on a deadline. Someone has a conference on Thursday, the stage screen needs a countdown the speaker can see while a producer adjusts it from the back of the room, and the free options stop at one device.
Growth turned self-feeding once the customer list became the marketing.
Nothing about this curve is dramatic, and that is the part worth studying. Going from about $8,000 a month to $25,000 took roughly two years, which averages to a few hundred dollars of new monthly revenue per week of work: real compounding, and invisible on any given Tuesday.
