Caught Peter Levels' tweet the week Skype shut down, shipped a replacement over a weekend, now at $14K/mo
Find markets where your competitors are dinosaurs: the incumbent VoIP players have been at it for 20-30 years and are still slow — so he replaced subscriptions with pay-as-you-go and shipped over a weekend, right into the Skype shutdown news cycle.
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Dennis is a solo developer with a background in diplomacy who taught himself to code in two months. In March 2025 Microsoft announced it was shutting down Skype; he saw Peter Levels tweet a call for someone to build a replacement, thought "why not me," and banged out the Yaphone prototype over a weekend. The product lets people make cheap international calls over VoIP straight from the browser (a few cents a minute), billed pay-as-you-go instead of by subscription, aimed at travelers, expats and businesses that make a lot of calls.
Reddit, with no audience at all. Dennis had 60 followers on X and had had them for years, so the launch went where follower count does not matter — he knew which subreddits to target and what tone to use, having been blocked from plenty of them on earlier projects.

Data credibility: Founder Dennis says in a Starter Story interview that he reached roughly $13.3-14K/mo in 7 months with 10,000 sign-ups, 4,500 paying users and 20 business customers; not third-party verified ⚠️ All revenue figures are founder-reported or estimated by the video creator — unaudited.
The first sale arrived minutes after the first Reddit post, which had never happened on any of his earlier projects and was the validation itself. What sold was credit rather than a subscription — the deliberate break from competitors who charge individuals about $30 a month and businesses a seat per person.
The compounding came from inheriting a departing brand's keyword real estate.
The long stretch came before Yaphone rather than during it. A trained diplomat who taught himself to code in two months from books and courses, Dennis spent years shipping side projects while freelancing to pay for them, and he is blunt about the results: they were ugly and they had no users.
