The founder took a twenty-year-old product category with no open-source entry and open-sourced all of it. This 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. Agents need an API-first scheduler and keep paying because they post without human effort.

It went where the users already were. It became an app in ChatGPT's app store and a plugin in Claude's directory and in Claude Code, with setups for Cursor and Codex. It did this in the months when these directories were new. It charges per tool call instead of a share of ad spend, so a small advertiser starts at US$49 a month. And it applied to the platforms' own API programs. The company says Google approved it in June 2026 and Amazon admitted it to its partner network.

It entered a market where people already paid for tools such as Taplio, and did the one core task better: writing the post. The founders' public posts brought the first customers and a lifetime-deal platform, and that deal paid for growth without investors. Subscriptions, partnerships with LinkedIn influencers, affiliates and a move to team plans came after.

A carousel needs both writing and design. Draft AI asks for a minute of speech instead and returns finished slides, plus scripts, threads and hooks from the same recording. It charges before the first result, so everyone who uses it has subscribed or started the trial of a paid plan.

It put the founders' marketing method behind a simple form. At that time people were trying to do marketing with ChatGPT and getting weak answers. A one-time price matched a need that comes rarely, and free tools brought search traffic without paid ads.

Many experts know that regular LinkedIn posts bring clients, but they do not have the time or the writing habit. UpLinked sells one narrow job, about one hour a week of LinkedIn posting for business-to-business experts, first in Dutch and later in English. Coaches and consultants who teach LinkedIn used it themselves and for their own clients. The sellers wrote that this word of mouth brought every customer, with no paid ads. TrustMRR recorded US$200,908 of Stripe payments to the founding company up to October 2026. Monthly revenue fell by more than half in 2026. The business was listed for sale, and since late October 2026 another company is named as its operator.

Two co-founders with full-time jobs elsewhere built a narrow tool for one post format that marketers found slow to design. They launched it on Product Hunt. A partner deal turned the editor into an SDK that other social media tools embed, which gave a second sales channel. Revenue peaked at US$14,386 in November 2025 and then fell to under US$4,000 a month by mid-2026, with the product still being rebuilt.

The founder was a LinkedIn ghostwriter with about 44,000 followers and a newsletter of about 17,000 readers. So he sold to an audience that already read him. He built the product around the interview that he used to do by hand for clients. It is not a text box that asks a model to write. The verified revenue grew from US$574 in April 2026 to US$19,343 in September 2026.

The founders first ran a marketplace that paid creators in free products, and saw that their clients' results were decided inside the ad platforms. In 2024 they rebuilt the company around ad buying and sold it themselves through demos to agencies and brands. They added a plan where their own staff run the ads. Stripe shows revenue almost four times higher in March 2026 than in October 2025, then a fall.

Josh Barkin wrote at launch that the top Google results for searches like "Valentines day gift ideas" were all roundups. He also wrote that bloggers and influencers lacked the time to research and write them. The two founders reused an earlier AI blogging tool that Kirill Shevchenko had built, launched on Product Hunt, and then sold lifetime licenses on AppSumo.

It took a narrower job than the general AI design tools, mobile apps only, for people who build apps without design skills. The three founders reused what they had learned from four earlier design tools and built it in three weeks. They showed finished designs on X before the launch. Each new Gemini model gave them a better result and a new demo to post.

The plugin lives inside Obsidian's community plugin store. The founder says that the store gave it organic growth with no ads or paid creators. The downloads reached 300,000 by the end of 2024, 1 million by February 2026 and 2 million by October 2026. The code is free, so there was nothing to sell until the company added a managed layer on top. The layer is hosted models, web search and tools that work without any setup. One-time lifetime plans, first Believer and then Supporter, brought large payments in single months. TrustMRR, reading the company's Stripe account, shows US$913,644 of revenue in total. Monthly recurring revenue was US$17,899 from 1,356 subscriptions on 27 October 2026, after a fall of about 51% from the best month, February 2026.

People already pay for an assistant and already ask it for pictures and video. CreativeClaw sells inside that conversation, so it needs no interface of its own, no sales calls and no provider accounts on the customer's side. Revenue stayed under US$5,300 a month for five months, then rose about 18 times in September 2026. This rise came after the founder had packaged the server for ChatGPT and prepared its entry in the plugin directories. He has not published the cause of the rise.

It aimed at regulated enterprises that needed AI agents on their own servers, with audit logs. The company said in 2025 that hundreds of organizations used it. Asana bought it in May 2026. Asana's quarterly report states the price.

Four founders, two of whom had built the drinks-delivery start-up Winelivery, looked for a profession. They wanted one that works with a large, fast-changing body of rules and had not yet adopted AI. They 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.

A studio portrait needs a photographer, a booking and days of waiting. AI SuitUp sold the same result, a photo for LinkedIn or a résumé, for a one-time price from early 2023. The larger packs had a money-back guarantee. It narrowed the offer to one use, professional headshots, and then built a landing page for almost every profession and a version for company teams. Stripe records US$648,649 of payments in total, but only US$35,743 of it in the last 12 months. So most of the money came in 2023, 2024 and 2025.

The founder had worked as a screenwriter and knew which part of the job is tool work. That part is the page format, and keeping characters and scenes consistent across a long draft. He built the editor around that work and kept the AI in the role of a helper. He says Claude Code wrote all the code. The beta grew through invite codes that users earned by posting about it. Monthly revenue rose from US$5,136 in May 2026 to about US$46,000 in August and in September.

It appeared in January 2023 inside Google Slides, a program where people already work. At that time writing slides from one sentence was new, and users showed it to each other without paid advertising. A blog about presentation topics then brought about 80% of new users from Google search, by the founder's account. Both channels weakened: search traffic fell, and Google added the same function to Slides. The verified total is real, and so is the fall: monthly revenue fell by half between February and July 2026.

Agencies that resell AI voice agents already have the AI. What they lack is a way to look like a company to thirty clients. They need a branded portal, usage billing and automations. ChatDash sells that layer and prices it per client slot, so it grows with the agency's client list. TrustMRR, reading the company's Stripe account, shows US$602,728 of revenue in total. It shows US$19,893 of monthly recurring revenue from 113 subscriptions on 27 October 2026, about US$176 a subscription. That is a fall of 60% from the best month in the table, November 2025.

Gemini Notebook had more than 30 million users and no folders, no export and no public API for personal accounts. Kortex sold the missing half for a few dollars a month. It found its users in the Chrome Web Store, where Google marked it Featured. It also found users in two lifetime-deal launches. The founder wrote that more than 100,000 users came 'without a single ad'. Most of the verified revenue arrived in February and March 2026, when a US$49 lifetime licence was on sale.

Its founders wrote some of the methods that the industry already used to run models cheaply, such as AWQ for 4-bit weights. They turned that research into a paid serving API. They proved the speed on a public benchmark and partnered with a cloud company that needed exactly that speed. Eleven months after its first public post, the partner agreed to buy it.

It launched in the month that AI models became good enough to write a whole app. It sold to people who cannot program, it charged from day one, and it was sold to a company that already had millions of customers.

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. He then tripled revenue from almost the same installs by moving and testing the paywall with Adapty.
