Case Study: How Robinhood Scaled Stock Trading with a User-Friendly App

1. Introduction

Before Robinhood, stock trading in the United States was often perceived as complex, expensive, and inaccessible to younger and first-time investors. Traditional brokerages charged commissions ranging from $5–$10 per trade, and trading platforms were often intimidating and technical.

Founded in 2013 by Vlad Tenev and Baiju Bhatt, Robinhood revolutionized retail investing by introducing commission-free trading through a mobile-first, intuitive app. This case study examines how Robinhood scaled rapidly, democratized access to financial markets, and disrupted the brokerage industry.
