The Company That Sold Trust
In 2010, a Bangalore-based brokerage was charging its customers a percentage of every trade they made. This was the universal model. Every brokerage in India, and indeed most of the world, made money the same way: a small slice of each transaction, paid by the customer, calculated as a fraction of the trade's value. If you bought shares worth one lakh rupees, you paid a few hundred in brokerage. If you bought shares worth ten lakh, you paid a few thousand. The math was so embedded in the industry that no one questioned it.
Nithin Kamath questioned it. He had been a trader himself for nearly a decade, and he had noticed something his peers had not: the cost of executing a trade had almost nothing to do with its size. Whether a customer bought ten shares or ten thousand, the brokerage's actual expense — server time, exchange fees, a few lines of code — was roughly the same. Charging by percentage was a holdover from an era when trades were processed by humans on paper. The technology had changed; the pricing had not.
So Zerodha did something that, at the time, looked like commercial suicide. They announced flat fees. Twenty rupees per trade, regardless of size. Equity delivery — the simplest kind of trade, where you buy and hold — was free. The established brokerages laughed. Their analysts pointed out, correctly, that Zerodha was leaving enormous sums on the table. A customer making a one crore trade was paying twenty rupees instead of perhaps ten thousand. The economics seemed obviously broken.
What the analysts missed was that the economics had never made sense in the first place. Zerodha wasn't undercharging; the rest of the industry was overcharging, and had been for years, because there was no competitive pressure to stop. Indian retail investors had simply accepted that brokerage was expensive, the way one accepts that flights to small cities are expensive. Zerodha's flat fee wasn't a discount. It was a correction.
The growth was slow at first, then it was not slow. By 2019, Zerodha had become the largest brokerage in India by active clients. By 2021, it had more than nine million customers and was consistently profitable, which is itself unusual — most companies that disrupt an industry on price spend years burning money to grow. Zerodha never raised venture capital. It funded itself from the start, paid out of operating cash flow, and kept its team small relative to its scale. In an industry obsessed with growth at any cost, Zerodha grew by being boringly profitable from the second year onward.
There is a temptation to tell this story as a parable about pricing innovation, but that's only half of it. The other half is trust. Indian retail investors had spent decades being mildly fleeced — by brokers, by mutual fund distributors, by relationship managers selling unsuitable products on commission. Zerodha showed up and didn't try to upsell anything. The platform was clean, the pricing was transparent, and the educational content the company produced through Varsity, its free learning portal, was genuinely useful rather than thinly disguised marketing. Customers noticed. They told other customers.
What Zerodha really sold, in the end, wasn't cheap trades. It was the experience of not being taken advantage of. In a market where that experience is rare, it turns out, people will move their money to find it.
