Why we picked it This is what a calm founder looks like staring at his own existential risk. Kamath writes, plainly and in public, that over 80 percent of Zerodha's revenue rides on two contracts and one regulatory change could wipe out a big chunk of it, then works the problem instead of panicking about it. No spin, no bravado: he has clearly thought about the worst case for years, which is exactly how you stay the calmest person in the room. A rare India-first model of naming the fire out loud and thinking clearly through it rather than spiraling.
