Mono: Revenue, team and how it was built

Team of 2 to 10 · 16 months after launch, revenue growing

Every team that builds with AI models ends up with several provider accounts, keys, invoices and SDKs. One gateway with open code replaces them, and a developer can read the code before sending traffic through the hosted version. In 2026 the founders added DevPass, a flat monthly price for coding agents with an allowance of up to three times the price in model usage. The verified monthly receipts grew from US$57,994 in January 2026 to US$249,922 in August 2026; TrustMRR does not split them by product.

The founder had written a marketing blog for ten years, so his own readers bought on the first day. He built the first version in 8 weeks with the no-code tool Bubble, because he had no money for developers. He sold one thing that the model makers do not sell: all of their models in one subscription.

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, found its users in the Chrome Web Store, where Google marked it Featured, and 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.

The plugin lives inside Obsidian's community plugin store, which the founder says gave it organic growth with no ads or paid creators: 300,000 downloads 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: 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 and US$17,899 of monthly recurring revenue from 1,356 subscriptions on 27 October 2026, after a fall of about 51% from the best month, February 2026.

In the founder's words on TrustMRR, agents like OpenClaw and Hermes can take on a solo founder's busywork, but setting one up means renting a server, wiring up API keys and fixing it when it breaks. Heyron does that setup for a flat monthly price, so a non-programmer gets a working agent in about two minutes. Stripe data shows nearly US$50,000 in its first month of sales, March 2026, and US$62,946 in April.

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, 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.

A normal chat window is one long thread, and a side question either breaks that thread or is never asked. The founder sold a fix for that one problem to heavy AI users. The subscription version earned little; the one-time licence that followed sold to many buyers, and Stripe data on TrustMRR shows US$131,070 in total. Sales then fell, because each one-time buyer pays only once.

The app costs almost nothing to run: the owner reports a profit margin of 99%, and the App Store page shows no new version since July 2025. A small, steady flow of downloads, about 2,500 in 28 days in October 2026, keeps about 150 paid subscriptions alive. The owner is an experienced app marketer who already sells more than a dozen other apps from the same developer account.

Many people get vague answers from chat models because their requests are vague. Prompt Builder sells the step in between: it asks up to three questions and writes the detailed request for them. Stripe data shows that people paid for this monthly, from US$346 in November 2025 to a peak of US$1,929 in May 2026.

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.

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.

It put a language model inside Google Sheets from November 2022, and Google's marketplace brought more than 201,000 installs. Few installs paid: US$52,136 of verified revenue in 47 months is about US$0.26 per install. Its most important result may be indirect: a request for a pitch deck for SheetAI led the founder to build MagicSlides, which by its own verified data earned about 14 times as much. SheetAI's own revenue is now falling, and Google has offered a similar AI function inside Sheets since June 2025.

Three founders who met in an Antler cohort in Berlin launched it in February 2025, in a category that, as The Next Web wrote in May 2026, "barely existed 18 months ago". With self-serve plans and unlimited users it signed 1,300 brands and agencies in about nine months, the company said, and two funding rounds within ten months paid for a large sales and engineering team in Berlin and New York.

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.

It sells a weekly subscription for a task students repeat before every test, and it charges from the first screen: the App Store reviews complain that the app cannot be used without paying. One small studio ships the same shell, the same legal pages and the same billing stack across six apps, so each new app costs little. The revenue, read from the app's RevenueCat account, reached US$23,480 in its best month and US$174,534 in total within twelve months of launch.

Site builders such as Webflow and Framer make it easy to build one site in one language. Adding languages with their own tools or with the market leader Weglot costs more as pages, visitors or languages grow. Linguana sold a flat monthly price with no charge per visitor or page, made manual translation free, and charged for machine translation by the word.

It sold a simple promise, a finished PowerPoint file from one sentence, at a low price: in 2024 and the first half of 2025 the archived pricing showed unlimited decks for US$9.99 a month. Stripe payments read by TrustMRR add up to US$60,120 since the start. The verified monthly figures also show a steady fall after November 2025, when the plans had moved from unlimited use to slide credits, and the founder put the business up for sale.
