Nikhil Kamath built his fortune by cofounding Zerodha with his brother in 2010 and helping scale the bootstrapped discount brokerage into one of India's largest trading platforms, then expanding into investment management and venture investing. [1][2]
Zerodha turned brokerage disruption into founder ownership
Kamath entered markets as a trader before cofounding Zerodha with his older brother Nithin in 2010. Forbes describes the company as a discount brokerage that disrupted India's brokerage market, while Zerodha identifies Nikhil as a cofounder responsible for investment and financial-planning functions. [1][2]
The company grew without the conventional venture-capital path used by many technology startups, allowing the founders to preserve unusually direct ownership of the brokerage they were building. That retained founder interest is the central link between Zerodha's operating scale and Kamath's personal fortune. [1][2]
Zerodha later expanded around a broader financial ecosystem, including Rainmatter, which backs fintech and financial-inclusion ventures. Kamath also cofounded True Beacon for wealthy investors, extending his business activity beyond brokerage while keeping Zerodha as the principal wealth engine. [1]
Business value and client assets must remain separate
The money customers hold or trade through Zerodha is not Kamath's personal wealth. His economic exposure comes from founder ownership in the brokerage and from other businesses and investments attributable to him, so customer balances and assets served by the platform should not be counted as his assets. [1][2]
Forbes identifies Kamath's fortune as self-made and rooted in financial services. The reviewed record supports a founder-created wealth path centered on a company started in adulthood rather than an inherited operating business, while not requiring claims about a uniquely severe starting disadvantage.
