India’s financial landscape has undergone a dramatic transformation in the last decade — and at the heart of this change is Zerodha, the country’s leading discount brokerage platform. Known for its tech-driven model, low-cost trading, and transparent practices, Zerodha has not only democratized investing for millions of Indians but has also inspired a new wave of fintech innovation across the subcontinent.

But what really sets Zerodha apart from traditional brokerages? How did it grow from a small startup to the largest stockbroker in India by active clients — without spending a rupee on advertising? Let’s dive deep.

#WhatIsZerodha

1. What is Zerodha?

Zerodha is India’s largest discount brokerage firm, transforming how individuals participate in financial markets by offering low-cost, high-speed, and technology-driven access to trading and investment tools.

Founded in 2010 by Nithin and Nikhil Kamath, Zerodha pioneered the flat-fee model in Indian brokerage by charging ₹0 brokerage on equity delivery trades and ₹20 (or 0.03%) per executed order for intraday, F&O, and commodities—regardless of trade size. This model attracted millions of investors and positioned Zerodha as a fintech leader in democratizing investing.

As of 2024:

• Zerodha has over 12 million clients
• Handles over 15% of total Indian retail trading volume
• Operates with no external funding—making it India’s largest bootstrapped unicorn
• Hosts multiple in-house and partner platforms: Kite, Coin, Console, Varsity, Streak, and Sensibull

Zerodha isn’t just a broker—it’s a full-stack financial ecosystem for retail investors, traders, and fintech developers.

#ZerodhaWorkflow

4. Basic Workflow: How Zerodha Works Internally

Let’s walk through how a stock trade flows through Zerodha’s architecture:

---

🔁 Example: Equity Trade Lifecycle

Step	Component	Action
1	Kite UI	User logs in and places a BUY order
2	OMS	Order validated for price, quantity, margins
3	RMS	Checks for exposure, leverage, and circuit filters
4	OMS	Sends the validated order to NSE/BSE via FIX
5	Exchange	Executes trade, sends confirmation
6	Zerodha OMS	Updates tradebook, holdings
7	Console	Logs contract note, P&L, and tax records
8	Email/SMS	Trade confirmation sent to user

A similar flow occurs in Coin (for mutual funds), but routed through BSE StarMF instead of NSE.
