0sec: 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.

It moved the structure of the founder's first app, Wrestle AI, to boxing, a sport that people can train alone. The structure is an AI breakdown of a training video, a calorie tracker and a weight-cut mode, all behind a subscription at the same prices. Users came from Meta ads and influencers, according to the founder's TrustMRR profile, with a self-reported marketing spend of US$10,000 a month.

It needs nothing but a phone: the camera replaces the sensors, the bag and the coach that earlier fitness products had to supply. The game layer of XP, levels and 1v1 matches gives users a reason to come back. The seller lists TikTok, TikTok Ads and Instagram as its marketing channels.

The founder has millions of followers. He turned a post format that was going viral on his own Facebook page into templates and sold the tool for about US$5. It made US$26,522 in about two months, and then revenue fell. No source says which channel brought most customers.

It aimed at regulated enterprises that needed AI agents on their own servers, with audit logs. The company said in 2025 that hundreds of organizations used it. Asana bought it in May 2026. Asana's quarterly report states the price.

Four founders, two of whom had built the drinks-delivery start-up Winelivery, looked for a profession. They wanted one that works with a large, fast-changing body of rules and had not yet adopted AI. They chose Italian accountants and labour consultants. They tested a first version with practitioners and sold monthly subscriptions. In October 2025 TeamSystem, an Italian maker of software for accountants, bought the majority of the company. Its press release said Normo.ai had €1.3 million of revenue in 2025.

A studio portrait needs a photographer, a booking and days of waiting. AI SuitUp sold the same result, a photo for LinkedIn or a résumé, for a one-time price from early 2023. The larger packs had a money-back guarantee. It narrowed the offer to one use, professional headshots, and then built a landing page for almost every profession and a version for company teams. Stripe records US$648,649 of payments in total, but only US$35,743 of it in the last 12 months. So most of the money came in 2023, 2024 and 2025.

The founder had worked as a screenwriter and knew which part of the job is tool work. That part is the page format, and keeping characters and scenes consistent across a long draft. He built the editor around that work and kept the AI in the role of a helper. He says Claude Code wrote all the code. The beta grew through invite codes that users earned by posting about it. Monthly revenue rose from US$5,136 in May 2026 to about US$46,000 in August and in September.

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.

One founder released it in August 2025, after Cal AI, released in April 2024, had shown that photo calorie counting sells. It has a hard paywall, a short trial and cheap yearly plans. It appears to have started in France: the French App Store shows 598 ratings against 138 in the US store. The owner lists TikTok as the only marketing channel.
