Tabtify: 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, does not train them, and spends its effort on design, data and paid user acquisition, which its founders call 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, collected early users and feature requests through lifetime deals on AppSumo in 2024, and in 2025 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 from August 2025, web plans with unlimited use at US$4 a month billed yearly, and a new group of customers, 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, and the founder says that an AI agent he made writes the blog posts.

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.

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, sells them mostly as one-time licenses, and, by the seller's account, finds its buyers through search pages instead of ads.

The founder first published the same idea as a free command-line tool on GitHub and npm in July 2024, and it collected about 2,100 GitHub stars and a Product Hunt launch. The paid desktop app then sold to people who wanted the result without a terminal: a US$19 one-time license for local models, or credits for cloud models. Revenue peaked in November and December 2025 and fell when the founder moved his time to another product.

General schedulers such as Hootsuite, Buffer and Later only publish posts made elsewhere. Velisto starts one step earlier, from the listing: one property becomes a campaign of posts, stories and a reel for each stage from Just Listed to Just Sold, and topic suggestions fill the weeks without a listing. It is narrow on purpose, built only for real estate, and charged from US$59 a month after a 7-day free trial.

Three of the four co-founders had LinkedIn audiences, together more than 480,000 followers, made of the people Kleo sells to, and the free extension had already reached tens of thousands of users. When LinkedIn stopped the extension, they sold a rebuilt paid version to that audience first, in limited groups of seats, before any public launch.
