Oleve (Quizard AI and Unstuck AI): Revenue, team and how it was built

The tutor is an AI model, so the company pays for computing and has no teacher to pay by the hour. That allows a yearly price of US$47.99 to US$79.99. Customers came from a very large number of short videos on TikTok and Instagram: first slideshows that the founder's own tool generated and that two people posted from about 12 accounts, then videos by paid creators. Yearly plans are paid in full on the first day, so the cash arrived early. Half of all revenue came in September 2026, and daily sales have fallen since.

Seven years of research at a Norwegian university produced the method, the training data and the avatar before the company existed. The founder is the professor who led that research, the university licensed the technology to her company, and public bodies that must train staff in child interviews are the customers. The filed accounts show revenue of NOK 816,000 in 2024 and NOK 2,176,042 in 2025, at a loss.

It launched in July 2023, when the ChatGPT plugins for PDF stopped at about 300 pages and Myreader took a whole library. It sold a cheap subscription limited by pages and questions, and it got its users from Google: the TrustMRR profile says the business has good SEO and about 30 sign-ups a day, and the site has a page for each kind of reader, from medical students to seminary students, and a free page for each of more than 40 public-domain classics.

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.

It starts from the student's own course files instead of general knowledge, so answers and practice questions point back to the material that the class uses. A free plan with monthly limits lets students try it, and Pro is sold by the week or by the month. Stripe shows about US$13,200 a month at the end of 2025; the seller says growth came with little to no marketing, and no source explains how students found it.

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, and TrustMRR, reading the site's Google Search Console account, counted 460,920 Google search impressions in 30 days.

Choosing a lure is the question that every new angler has at the water, and a phone camera plus weather data can answer it in seconds. One developer built a narrow app around that single question, put the answer behind a subscription, and promoted it with short videos on TikTok. Sales are highest in the summer fishing months.

System design interviews are hard to practise alone, because the value is in the follow-up questions that a senior engineer asks about your design. A language model that can read the diagram and the chat can ask those questions at any hour. The free plan gives unlimited practice, and the Pro plan at US$14 a month sells the analysis, the score and company-specific questions.

Questgen started as free open-source code on GitHub whose README sends readers to questgen.ai, where the paid plans are. Both apps then won search traffic for exact phrases such as "AI meme generator", and Supermeme says it has spent nothing to acquire its users. Costs are low: in June 2022 the founder said his two products were profitable at US$500 and US$100 a month. So a part-time team with no investors can keep them running.

Two founders with consumer-app experience built a prototype in under a week, launched a free web app in July 2023, kept it a web app for twelve months, and added native phone apps in August 2024 once the product had its users. It positions itself as a companion between therapy sessions, not as therapy, and gets recommended by therapists and coaches. The company said in June 2025 that 7,500 paying customers came from that positioning and a long-term memory system that chat models did not offer.

The two founders had run an email marketing agency in college, so they planned how to reach customers before the product was good. They built the app without coding experience, with Claude and Cursor, released it with crashes, and fixed it in public. Growth came from free posts on Instagram, TikTok and Reddit, then from a small group of creators who post about the app every day, then from paid ads on Meta. Co-founder Giancarlo Sarti told Starter Story in March 2026 that the app made US$12,900 in February 2026.

Many English learners understand more than they can say, and a human conversation tutor costs money and needs a schedule. A voice model can listen and answer at any hour. TalkEasy wraps that in lessons built around the learner's own reasons, a correction view, and a progress page that brings old mistakes back for practice.

It sold speed to people who gave up on manual food logging, it paid 250 influencers fixed monthly fees to reach them, and it had a 30-dollar-a-year price. The rented model made the hard part cost almost nothing to build.

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.

The founder took a twenty-year-old product category with no open-source entry and open-sourced all of it, which 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, which 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, and it treated the economics of each ad channel as the product to optimize. Cheaper attribution let it test low-cost traffic, and 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, then tripled revenue from almost the same installs by moving and testing the paywall with Adapty.

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.

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.
