Robinhood (NASDAQ: HOOD) and Affirm (NASDAQ: AFRM) are both high-growth fintech companies that aspire to disrupt legacy financial institutions. Robinhood’s introduction of commission-free stock and cryptocurrency trades attracted a new generation of retail investors and forced traditional brokerages to eliminate their fees. Affirm is challenging credit card companies with a BNPL (buy now, pay later) payment network that breaks larger purchases into smaller monthly payments.
