Years ago, Facebook colonized the web with its Like and login buttons. They plastered its name everywhere, reminding existing users to visit the site. They generated content you could interact with back on Facebook. And they made your Facebook account more valuable since you could instantly bring your friend graph anywhere, encouraging sign-ups. The strategy entrenched Facebook as the central social network, boosting its push to become a ubiquitous utility. Now, Robinhood is doing the same with what’s essentially an embeddable Trade button. Bhatt hopes Robinhood can walk the same path. “If we do this correctly and don’t screw it up royally, in 5 years it’s going to be completely unnecessary to build any more brokerages.”
