Robinhood co-founder and CEO, Vlad Tenev, says almost all engineers at the company have adopted AI coding tools. Engineers at the stock trading and investing app Robinhood are using AI to generate new code instead of writing it themselves. According to Tenev, over 50% of new code at Robinhood is AI-generated, the same percentage as Salesforce.
