Four founders, two of whom had built the drinks-delivery start-up Winelivery, looked for a profession that works with a large, fast-changing body of rules and had not yet adopted AI, and chose Italian accountants and labour consultants. They tested a first version with practitioners and sold monthly subscriptions. In October 2025 TeamSystem, an Italian maker of software for accountants, bought the majority of the company; its press release said Normo.ai had €1.3 million of revenue in 2025.

It sells one narrow job to one profession in one country: missed calls at small Belgian law firms. The site, the blog and the terms are written for lawyers at the Belgian bars, in French, with answers about professional secrecy and GDPR that this buyer asks first.

The founders are lawyers who built the legal departments of two Berlin startups, and the CEO writes that he knows the frustration with old legal software from that work. LawX replaces the whole office system instead of adding one more AI tool, it charges one price per user for the whole team, assistants included, and every AI suggestion waits for a person to approve it. tech.eu reported in May 2026 that the next step was the broader law firm market.

One founder had worked as a corporate lawyer and the team sold directly to law firms and banks that it already knew. The product was built on Indian court material, which global tools cover less well. Customers made it part of daily work: when the platform went down for maintenance, users called and messaged the team to ask when it would return.

Three founders built it without outside money in 2023, and the first message, that it replaced lawyers, scared the customers away. They changed it into an assistant for lawyers, connected it to the Spanish official gazette and court decisions, and had it take the Spanish judiciary entrance exam in front of a notary. According to Merca2, that public test turned a handful of customers into hundreds a month. Doctrine, a French legal AI company, bought it in February 2026.

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.

Questgen started as free open-source code on GitHub whose README sends readers to questgen.ai, where the paid plans are. Both apps then won search traffic for exact phrases such as "AI meme generator", and Supermeme says it has spent nothing to acquire its users. Costs are low: in June 2022 the founder said his two products were profitable at US$500 and US$100 a month. So a part-time team with no investors can keep them running.

Three founders treated each app as an experiment in pricing and paywalls. Lessons from Pixi, the first app, went into Cue. The studio rents the models, does not train them, and spends its effort on design, data and paid user acquisition, which its founders call the three Ds.

It entered a crowded category in March 2025 with paid advertising instead of a personal audience, and it treated the economics of each ad channel as the product to optimize. Cheaper attribution let it test low-cost traffic, and weekly advances on App Store payouts let it put each week's earnings back into ads within days instead of 45. Adapty, the company whose software runs the app's subscriptions, published the figures under its own name.

Its result is a before-and-after picture of the user's own face, which a short video shows in seconds. The founder chose TikTok as the channel before he built the app, then tripled revenue from almost the same installs by moving and testing the paywall with Adapty.

A developer in Bangalore formed a company with an American YouTuber who already had an audience of people who want faceless channels, so customers paid from the first day. Affiliates receive 33% of every payment and brought about a tenth of all revenue, and Meta ads brought more. Nobody could use the product without paying, so no free user consumed paid AI models. Verified revenue reached about US$85,000 a month for six months, and then fell by half.
