Founders scale AI study app to $13M revenue
Rudy Arora and Sarthak Dhawan, childhood friends who left Northwestern and Duke after their sophomore year, have grown their AI study app Turbo AI (formerly Turbolearn) to $13 million in lifetime revenue with a 10-person team, according to Business Insider. The app, which turns lecture recordings or documents into notes, flashcards, and quizzes, had reached 5 million users and an eight-figure annual run rate by late 2025, per TechCrunch, and has since drawn professional users including consultants and analysts at Goldman Sachs and McKinsey. The founders told Business Insider they now write little of their own code, relying heavily on Claude Code, with cofounder Dhawan saying he can feel his "coding skills atrophying" even as the tool lets a small team ship at the pace of a much larger one. The company has raised only $750,000 in outside funding and says it has stayed profitable throughout.
The more interesting data point here is not the $13 million headline, it is the founders' own account of what heavy AI-code-generation use costs them: cofounder Sarthak Dhawan says he can feel his coding skills atrophying even as Claude Code lets a six-engineer team ship at a pace that would have needed a much larger team two years ago, a tradeoff practitioners scaling small AI-native teams should plan for rather than treat as a one-off anecdote.
What happened
Rudy Arora and Sarthak Dhawan, friends since middle school, built what became Turbo AI (originally Turbolearn) after struggling to take lecture notes as freshmen at Northwestern and Duke in fall 2023. They launched the app, which uses AI to convert recorded lectures, PDFs, or videos into notes, flashcards, and quizzes, in January 2024, grew it largely through TikTok content, including paying creators $5 per video plus bonuses for virality, and left college at the end of their sophomore year. Business Insider reports the app was generating almost $500,000 a month by March 2025 and has crossed $13 million in lifetime revenue with a 10-person team, including six full-time engineers. TechCrunch reported in October 2025 that the app had reached 5 million users and an eight-figure annual run rate, and that its user base had broadened beyond students to consultants, lawyers, doctors, and analysts at firms including Goldman Sachs and McKinsey.
Financial context
Despite the growth, Turbo AI has raised only $750,000 in outside funding, according to TechCrunch, and the founders say they have stayed cash-flow positive and profitable throughout rather than raise a larger round on investor interest. Dhawan previously built UMax, an appearance-advice app that reached number one on the App Store with 20 million users and $6 million in annual revenue, and Arora specializes in the social-media growth tactics that drove Turbo AI's early TikTok-led scaling.
For practitioners
Dhawan told Business Insider that AI code-generation tools were "pretty terrible" when the app launched, so he wrote the initial codebase by hand; he now relies on Claude Code for most day-to-day development and says his role has shifted to planning, describing systems at a high level, and reviewing AI-generated code rather than writing it. His caution, that a codebase can "shift into this entity that you don't understand" as AI writes more of it, and that he can feel his own coding skills atrophying, is a concrete version of a tradeoff every team leaning on coding agents should track: velocity now against code comprehension and maintainability later.
What to watch
Whether Turbo AI's shift from a student tool toward a broader professional note-taking and document-summarization product, where it competes with Otter, Fireflies, and YC-backed YouLearn, changes its funding posture, and whether the founders' account of shrinking hands-on coding involvement becomes a more common pattern as other small AI-native teams scale revenue with lean engineering headcount.
Key Points
- 1Rudy Arora and Sarthak Dhawan grew their AI study app Turbo AI to $13 million in lifetime revenue with just a 10-person team.
- 2The company has raised only $750,000 in funding and says it has stayed profitable rather than chase a larger round.
- 3Cofounder Sarthak Dhawan says heavy use of Claude Code boosted output but left him feeling his own coding skills atrophying.
Scoring Rationale
A well-corroborated founder profile (TechCrunch independently verified the company, funding, and user numbers) offering a concrete, named case study of a small, Claude-Code-heavy team scaling to eight-figure revenue while staying bootstrapped; useful anecdotal evidence for AI-native team practices but not a technical or industry-wide event.
