At Knowlify, four University of Florida friends are turning dense documents into animated explainers. CEO Ritam Rana’s route runs from autonomous boats and student coding projects to Y Combinator, a $3 million round, and a stubborn wager on video as the default language of work.
Knowlify is a Y Combinator (S25) startup building a text-to-explainer video engine that turns documents, PDFs, textbooks and plain text into narrated, animated videos in minutes. Founded by four University of Florida classmates, the company offers a self-serve platform for teams plus a managed studio for high-stakes productions, and has generated over 200,000 videos for organizations including Amazon, ByteDance, Flexport, Supabase and Zoho. In October 2025 Knowlify raised $3 million to make video the default medium for explaining complex information.
