Built with AI

The founder took a twenty-year-old product category with no open-source entry and open-sourced all of it, which gave him millions of Docker downloads and 37,000 GitHub stars without a marketing budget. Revenue stayed small for a year. It multiplied when he turned the product toward people who automate their posting with n8n workflows and, from late 2025, with AI agents, which need an API-first scheduler and keep paying because they post without human effort.

The founder had an audience before the product existed: a daily YouTube show about SEO since 2023 and an X account that has 62,000 followers today, so the first customers cost nothing. A developer co-founder built the software with AI coding tools. The product started as one plain rank tracker at US$19 a month, grew into a bundle at US$57 to US$2,997 a month, and by July 2025 the first payment of a new customer from a paid ad covered the cost of that ad.

The first customers came from a lifetime-deal sale on AppSumo, at a time when the product had no AI at all. That gave about a thousand users, word of mouth and a Powered by Guidejar link on every free guide. From April 2024 the founder sold subscriptions instead, and added AI writing, voiceover and translation to the paid plans, metered in credits.

It entered a crowded category, habit trackers, with a free tracker and a paid AI coach on top. The founder shipped 83 versions in 21 months, so the product changed every week or two. Many buyers pay for a year at once, and whatsthe.app read that the money in the last 28 days was almost twice the monthly recurring revenue.

One person built it in about two months for US$680, using a rented language model for the hardest part for non-experts: writing the text of the site. He listed it on many launch sites and directories, reached 22 paying customers, and sold it on a small-startup marketplace 21 days after listing.

Two founders shipped eleven products in about four months and kept the one that made money. They sold it on the platform it served, gave an audience owner a share of profits instead of a sponsorship fee, and used a language model to make writing faster, not to replace it. Fifteen months after launch, with about US$1 million a year in revenue, they sold to a larger French software company run by a former schoolmate.

An Amazon seller who could not code built the research tool he needed in 48 hours with Cursor, then offered it to Legacy X, a coaching program for Amazon sellers that he had bought two years earlier. Legacy X took a share of the business, and its students were the customers from the first day. He says it reached US$10,000 a month in 30 days and US$30,000 a month by June 2026.

The founder said in April 2026 that he built the whole platform in a weekend with Replit for US$400, sold a US$15,000 training contract through LinkedIn messages on the first Monday, and that AI tools let him reach a US$1 million a year run rate alone before he hired anyone. Then he turned one-off training days into a recurring retainer, and the retainer into software.

The founder said he built it for his own need: a place close to the phone for crypto wallet keys and pictures of IDs and birth certificates. He said the older vault apps in the App Store have millions of users and he could not beat them in App Store search, but they ignore the web. So, he said, coding agents publish one guide a day for web searches where his site appears but gets no clicks, and those readers download the app. He said lifetime purchases are most of the money.

According to Acquire.com's article, the founder saw that cold email and LinkedIn messages had become so common that buyers recognized and ignored them, so he moved the first contact to paper and kept the digital tools around it. He put up a landing page with a payment link before the product was built; according to Acquire.com's article of 2 July 2026, one customer paid US$2,500 a month within two weeks and the business reached US$120,000 in annual recurring revenue six weeks later. It was then sold through the Acquire.com marketplace, and no price was published.

The founder had spent years in payments and had just failed with a stablecoin wallet for AI agents under the same name. In August 2026 he relaunched the brand as a merchant of record aimed at sellers in countries the big processors skip, with the first country guides written for the Western Balkans. The company's about page quotes an Indie Hackers interview of 6 October 2026 whose title says the relaunched business reached US$9.5K of monthly recurring revenue in two months, and its home page counts more than 400 sellers and 1,400 payments since August 2026.

Many women on Xiaohongshu, a Chinese social app, already lit their selfies by opening a solid-colour picture on a second phone, which took several steps: search, open the post, zoom, raise the brightness. The founder said in December 2024 that his partner's remark showed him this need and that he decided to build the app in under five minutes. He said he built it in about an hour with Cursor, posted it on Xiaohongshu, and answered the comments as a person; when copies appeared, he released the paid version at CNY 1 and, as he told Qbitai, turned the act of charging into a marketing event.
