LumeVoice: Revenue, team and how it was built

Started small, grew after funding · 26 months after launch, revenue growing

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 and does not train them. It spends its effort on design, data and paid user acquisition. Its founders call these the three Ds.

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 first apps that combined OpenAI's Whisper and ChatGPT for voice notes appeared in 2023, and the founder found them "not implemented well enough". His team built a simpler one, and collected early users and feature requests through lifetime deals on AppSumo in 2024. In 2025 it grew with advertising and paywall tests measured in Adapty's subscription data.

For its first 20 months the product brought in about US$3,500 a month. Then three things came together. Phone apps with weekly plans came from August 2025. Web plans offered unlimited use at US$4 a month billed yearly. A new group of customers arrived: people who make songs with AI generators such as Suno and need the last step done for them. Monthly revenue rose 7.2 times between January and July 2026. No source states which of the changes caused the rise.

It started as a free Chrome extension that the founder built for his father, then sold unlimited dictation everywhere for a low monthly price. The AI model is cheap to rent: Groq lists Whisper at US$0.04 to US$0.111 per hour of audio. Users came from Google. The site has more than 1,000 pages, one for each app and each need. The founder says that an AI agent he made writes the blog posts.

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 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. The founder stopped them in August 2026 because the costs were larger than the revenue.

It answered a request that people already typed in public: what does the person in this viral video say? A free bot replied inside X, where the request was made. The website sold the same service for longer files at a few dollars a month. The speech and translation models are bought from other companies, so one person could build and run it.

The team says that people in real meetings do not like a translator that speaks for them. So Deeptrue mainly prompts the user to speak for themselves. It works with any meeting app through a virtual microphone, instead of a bot that joins the call. It rents speech, language and voice models by the minute. So a small team can sell it with metered plans.

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.

Speaking is the part of a language that learners practice least, because a human partner is expensive or not available. An AI tutor that listens and answers by voice is available at any hour for a fixed subscription. The founder chose search as the way to find learners. The website has about 1,600 pages in ten languages. TrustMRR, reading the site's Google Search Console account, counted 460,920 Google search impressions in 30 days.

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.

Heavy users of AI chat apps lose old answers, because the apps had no folders, no filtered search and no bulk export. AI Toolbox adds these inside the apps, for four apps at once, and sells them mostly as one-time licenses. By the seller's account, it finds its buyers through search pages instead of ads.

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 entered a crowded category in March 2025 with paid advertising instead of a personal audience. It treated the economics of each ad channel as the product to optimize. Cheaper attribution let it test low-cost traffic. 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. He then tripled revenue from almost the same installs by moving and testing the paywall with Adapty.

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.
