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.

It reached the App Store early, in July 2023, with the simplest form of the idea: press one button, get a transcript and a summary. The founder paid for Meta ads while they still worked for a new kind of app, tested paywalls constantly and moved buyers to annual plans. He works alone with AI coding tools, so in his own 2026 account about US$3 million of about US$7 million a year stays as profit.

The founder had an audience before the product existed. He had a daily YouTube show about SEO since 2023 and an X account that has 62,000 followers today. For this reason 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, and grew into a bundle at US$57 to US$2,997 a month. By July 2025 the first payment of a new customer from a paid ad covered the cost of that ad.

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.

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.

The product goes where the customers already are. A shop owner does not install a new app or learn accounting software. Instead, the owner writes into a chat. The founder wrote of having worked as a data scientist at a microloan company and of running a café. So the founder knew both the bookkeeping problem and the reason banks ask for records.

The founder, a digital nomad, had collected more than 1,000 receipts from many countries to track his own spending. He built the app for that use. It reads every line item instead of only the total, which matters for travellers with receipts in foreign scripts and currencies. Small, steady releases widened the market: 25 versions between 21 January and late October 2026. A translation of the app into 52 languages did the same, without a team.

The founder built a tool that he wanted for himself as a runner. He trained with a human coach from late July 2025 and stopped a marathon at kilometre 32. The product keeps what he valued in that coaching: varied sessions, pace ranges and a plan that follows what he runs.

The two founders built it first for their own SaaS products and Shopify apps. The reason was that they had to keep one support workspace open for every product and felt they had to answer at night. They then opened it to other founders with the same problem, with unlimited projects on every plan and a fixed price per team size.

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.

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.
