Lancer

A calendar that publishes posts to more than 30 social networks: X, LinkedIn, Instagram, TikTok, YouTube, Reddit, Bluesky, Discord and others. The whole code is open source, so anyone can run it on their own server for free; the company sells the hosted version from US$29 a month. Since 2025 AI agents such as Claude, ChatGPT and OpenClaw can connect to it through an MCP server, a command-line tool and a public API, so an agent drafts and schedules the posts and a person approves them in the calendar.

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.

An AI agent for paid advertising that works inside ChatGPT, Claude, Claude Code, Cursor and other AI assistants. It connects to the customer's ad accounts at Google, Meta, LinkedIn, TikTok, Amazon and ChatGPT Ads, researches keywords, builds campaigns (always created paused), reports results and finds wasted spend. Scheduled agents can also watch the accounts and make reversible changes. The customer pays the ad platforms directly.

It went where the users already were: an app in ChatGPT's app store, a plugin in Claude's directory and in Claude Code, and setups for Cursor and Codex, 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.

A LinkedIn lead finder for B2B sales teams. You list LinkedIn profiles to watch; traxy collects the people who like, comment on or repost their posts, scores each one against your ideal buyer, adds an email address and phone number, and an AI agent can write and send the first message.

The founder already ran a LinkedIn ghostwriting agency and built the lead tool that the agency needed. He sold it with the tool itself: traxy found the leads, and his team contacted them. Daily posts on X added trials, and credit-based prices let heavy users pay more.

An AI assistant that you reach by message. You send a voice note, a text, a screenshot or a forwarded email on WhatsApp, Telegram, iMessage, Slack or email, and it writes notes, tasks, draft posts and CRM updates into Notion and more than 1,000 other connected apps. It started as a voice-to-Notion tool. In 2026 it added a desktop app, a cloud computer, automations, and connections to Claude, ChatGPT and coding agents.

It reached people inside the chat app that they already open all day, so capturing an idea on a phone took one voice note. It aimed first at Notion users, whom the company told that ideas get lost on the phone. Ads on Facebook and Google then paid for fast growth in early 2026, until the founder stopped them in August 2026 because the costs were larger than the revenue.

A web application that turns an idea or a script into a finished video in which no person appears on camera: a script written by a language model, a synthetic voice, stock footage or AI images, captions and music. It makes vertical shorts and horizontal videos of up to 20 minutes, and it can upload to a YouTube channel that the customer connects. Customers pay a monthly or yearly subscription that includes credits. There is no free plan and no free trial.

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.

A church connects the audio of its service, from a microphone or the sound desk, to Glossa in a browser and starts a stream. Glossa turns the speech into text, translates the text, and reads the translation aloud with a synthetic voice. Each visitor scans a QR code, picks one of more than 100 languages on a phone, and listens with earphones or reads the captions. The church needs no receivers and no interpreter booth. It pays for the minutes of speech in each language, not for the number of listeners.

Churches with members from many countries meet every week, and the older solutions cost too much for most of them: an interpreter for each language, or radio receivers to hand out and collect. Glossa charges US$5 for one hour of speech in one language, counts by the minute, and charges nothing for silence, songs or extra listeners, so a small church can start with four free hours and then a few dollars a week. The product is shaped for this one buyer: captions go into ProPresenter and OBS, which churches already run, and a church can fix how names, Bible quotations and its own terms are translated. A very small team can offer this because the speech recognition and the voices are rented from model companies and paid by use.

A user gives a topic, a text, a PDF, a web address or a YouTube link, and a language model writes a slide presentation from it. MagicSlides runs as an add-on inside Google Slides and as a web application that exports editable PowerPoint, PDF and Google Slides files. Since July 2026 the same account also includes AI tools for spreadsheets, documents, meeting notes and a design canvas, under the name Magic Suite.

It appeared in January 2023 inside Google Slides, a program where people already work, when 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.

A web application for people who sell simple books through Amazon's Kindle Direct Publishing. The user describes a book, and AI models produce its pages: line drawings for coloring books, puzzles and mazes for activity books, text and layouts for journals and planners, and a description for the Amazon listing. A subscription buys credits. By the terms of service one generated image costs 200,000 credits, so the smallest plan, with 40 million credits a month, pays for about 200 images.

It sold one narrow job to a group that already existed: people who learn from YouTube channels and paid courses how to publish many simple books on Amazon. The product carries that group's own word in its name, tutorial channels in English and Italian showed it from January 2025, and the site runs an affiliate script. Two thirds of the US$642,409 came in the first 14 months, at about US$30,300 a month. The last 12 months average about US$17,600 a month.

A web app that writes LinkedIn posts in the member's own style from an idea, a voice note, a video, an article or a short interview with an AI, then schedules and publishes them. Team plans add approvals, a shared calendar and analytics for each employee. It can also be used from inside Claude and ChatGPT.

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.
