Prometheo: Revenue, team and how it was built

It launched the obvious application of a new model within weeks, with a pricing page on the first day. The founder built the parts around the model instead of a model, so every model upgrade improved the product for free. Then it moved from a consumer toy to business customers who stay.

Agencies that resell AI voice agents have the AI already; what they lack is a way to look like a company to thirty clients: 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 and US$19,893 of monthly recurring revenue from 113 subscriptions on 27 October 2026, about US$176 a subscription, after a fall of 60% from the best month in the table, November 2025.

Hourly and field workers answer text messages but ignore email and job portals, and a recruiter cannot call every applicant at night or on a weekend. TextWork replies at once and turns the chat into a structured report. Stripe data read by TrustMRR shows US$29,372 in the twelve months to 26 October 2026 and US$2,919 of monthly recurring revenue, but from only two paying subscriptions, so the business is small and depends on very few customers.

Large online groups get the same questions again and again, in many languages, and scam messages arrive at hours when no moderator is awake. C12s answers from the project's own documents and deletes the scams, so a small moderator team can cover the whole day. Its blog and FAQ name Web3 projects and gaming groups as typical users, and its developer, the Lisbon IT firm Momentum One, already sold Discord set-up and moderation services to such projects.

The two founders built it first for their own SaaS products and Shopify apps, because 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.

This page is about a very small verified result, not a large one. Stripe data on TrustMRR shows US$99 every month from January to October 2026 and one active subscription. That figure matches the monthly price of the top plan, so it is probably one customer. The story shows what a solo founder can build and sell, and how far one paying customer is from a business.

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.

Tradespeople already use WhatsApp all day on the job site, and many write quotes by hand or in a spreadsheet. Tutti puts the office work into that chat, so the customer has nothing new to install or learn. It sends messages through Meta's official WhatsApp Business Platform, which lets one founder run the service without a phone app as the main product.

Platform analytics show a creator the second at which viewers leave, but not the reason. The product's own page puts it this way: "Analytics shows where they leave. TikAlyzer shows why and what to change." It sells that reason as a subscription with a 7-day money-back promise, and pays affiliates a commission of 30% on every payment, as its home page states.

Many recipes now live in short videos, where the ingredients are spoken or shown and never written down. A model that can watch a video and write out a structured recipe turned an old app category, the recipe keeper, into something that works for these videos. One developer built it on rented models and sells it through the app stores as a subscription.

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.

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.

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.
