Robinhood

The youngest company in the traditional finance category—founded in 2013 by former Stanford roommates Vlad Tenev and Baiju Bhatt—the stock-trading firm pitched itself as a trading platform for the 99%. Robinhood saw meteoric growth in the beginning of the pandemic amid the meme-stock craze, later adding a suite of crypto-trading options to its offerings, including a recently released wallet and the ability to buy almost 20 cryptocurrencies.
