Robinhood (company) – Wikipedia

Robinhood was founded in April 2013 by Vladimir Tenev and Baiju Bhatt, who had previously built high-frequency trading platforms for financial institutions in New York City. The company’s name comes from its mission to “provide everyone with access to the financial markets, not just the wealthy”. Tenev noted that executing a trade cost brokerages “fractions of a penny” but they typically charged fees of $5 to $10 per trade, as well as required account minimums of $500 to $5,000.
