AI research and writing tools grew through repeatable short-form video formats aimed at students and researchers.
profitable · 5M+ users; founder attributes tens of thousands of paid users and $500K+ to one recurring video series
One well-matched video format can outperform unrelated posts: keep the winning premise, change the opening scene, and measure paid users rather than views.
Fewer bars = easier, cheaper, or faster for an AI-assisted solo builder. Editorial judgments based on the case details.
Jenny AI is an education technology product founded by David Park that helps researchers research, write, and use AI assistance across related tasks. Park says the business generates more than $10 million a year, is profitable, and has more than five million users. The company attributes most of its growth in the last two years to a short-form content system built around TikTok and Instagram. The approach starts by studying the target audience’s interests, the creators they already watch, and the formats that hold attention. The team then tests creators, hooks, accounts, editing styles, and content concepts before turning a winner into a repeatable series. Park describes a “point of view” video format built around a student realizing an essay is due and using Jenny; the team posted versions about twice a week for about half a year. He attributes hundreds of millions of views, tens of thousands of paid users, and more than half a million dollars to that series. These are creator-reported figures from the interview, not independently audited results.
For Jenny, the first useful audience is a specific student or researcher group with a recurring writing deadline, not everyone who is curious about AI. Begin by asking users which creators they watch, which study pressures show up in their feeds, and what makes them stop scrolling.

Data credibility: Starter Story interview with founder David Park. Revenue, profitability, user count, and the views, paid users and revenue he attributes to the essay-deadline video series are founder-reported and were not independently audited. No pricing or plan mix is given.
A short-form video business like Jenny should connect every creative test to a clear path from curiosity to a useful first session. Park credits one recurring essay-deadline series with tens of thousands of paid users and more than half a million dollars.
Jenny’s repeatable growth loop came from turning one effective short-form concept into a series, then distributing variations across accounts and platforms.
Short-form distribution can feel random: a carefully made clip may receive little reach while a small account unexpectedly outperforms a large one. Jenny’s approach treats that uncertainty as a testing problem.
