Quad Chat: 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. Its allowance is 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. 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.

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.

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. 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.

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.

People who pay for ChatGPT, Claude, Gemini and Perplexity separately can pay once instead. The founder sets one price for all models because a user sends about the same number of messages in one tool as in several. He limits only the most expensive models. He adds new models as they appear, often several in one week, and publishes the revenue daily.

The app costs almost nothing to run: the owner reports a profit margin of 99%. 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.

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.

It put the newest video models, among them ByteDance's Seedance 2.0 from 14 April 2026, inside a storyboard editor that keeps characters consistent. Revenue grew from US$645 in May 2026 to US$32,697 in July. Then it fell by three quarters by September, and no source says why.

The founder is a marketer who is not a programmer. He said in an August 2026 interview that he built the first working version in two weeks with the AI code editor Cursor. He said he launched in June 2025 and reached about US$20,000 a month in four months with paid ads. These ads cost less in Israel than in the United States. He then gave two well-known Israeli fitness influencers half of the revenue from Israel instead of paying them per post. He said that this took the app to over US$81,000 in April 2026.

The founders say that founders either spend too much time on email or lose deals and hires because a thread slipped. Slashy started as a general AI agent for work tools. It then moved its focus to one place where that agent is needed every day: the inbox.

Churches with members from many countries meet every week. 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. A small church can therefore 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. 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.

Writers who cannot draw had no fast way to see their story as a comic. TabStory puts several image models behind one comic workflow with storyboards and character consistency, and sells credits by usage. Stripe-verified revenue grew from US$495 in May 2026 to US$12,143 in October 2026.

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.
