An AI study agent for university students, sold student-to-student around exam pressure before any school signed on.
€130K ARR in the first month · 2,500 sign-ups in two days (founder posts, relayed by creator)
Isabel's earlier app had a big waitlist that vanished at exam time; Klar sold the exam-day pain at a career-fair table, with card details on the spot, before building.
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Klar is an AI study product built by three business students who met at Uppsala University: CEO Isabel Storgårds, product designer Andreas Melander, and student-facing cofounder Eric Götborg. The product began as Tentaklar, an exam-preparation tool that turns old exams and notes into likely mock questions, then broadened into an AI learning agent. The creator reports $600,000 ARR seven months after launch and describes rapid campus adoption, including 2,500 sign-ups in two days and a 4,000-person waitlist. Those revenue figures are self-reported; the video notes there was no payment screen shown and says public accounts had not yet confirmed the post-launch revenue. The founders first sold directly to students at a career fair, then used student word of mouth and TikTok campus content. A university later partnered with Klar, offering a free month to 35,000 students. The case shows a focused student-first wedge expanding toward institutional distribution.
Klar's first customers were approached in person at a campus career fair, where the founders tested how students described the problem and whether they would pay. A generic “study helper” sign drew little attention, so they reframed the pitch around exam pressure and the cost of ChatGPT Plus.

Data credibility: The $600K ARR, the $500K-to-$600K jump in six days and €130K first-month ARR come from the founders' own posts and interview clips, relayed by the creator. The creator notes no payment screen was shown, that 1 September billing of free-summer users may inflate ARR, that "80% conversion" is pitch-to-sign-up, and that Swedish filings show basically zero sales last year (pre-launch).
The earliest dollars came from preselling the exam-preparation use case face to face. The team did not wait for a polished platform; they tested whether students would pay for help turning old exams and notes into likely practice questions.
Klar's growth loop combined student usefulness with peer visibility. The founders reported 2,500 sign-ups in two days near launch and a 4,000-person waitlist, followed by word-of-mouth growth.
Early institutional resistance created a difficult stretch for Klar: the university asked the founders to stop promoting AI study use after a social post drew attention. Their route forward was to keep serving students directly and make adoption visible through campus-focused content and peer use.
