Built Zerodha Varsity, the clearest Indian case study in growing a category leader through free education instead of ads
Why they're worth your time
Zerodha grew to category leadership with almost no advertising spend, and Varsity is the machine that did it, so studying how Karthik structures the content, the depth ladder and the free-forever decision teaches inbound growth at a scale most content teams never reach. He also answers reader questions in public, which shows the feedback loop.
Background
Karthik Rangappa heads investor education at Zerodha and wrote Zerodha Varsity, the free markets curriculum that became one of India's most read finance education properties. He has since extended it into Varsity Live, Varsity Junior and school outreach programmes. He writes and answers questions publicly on the Varsity modules, Z-Connect and X.
