Robinhood has the begging bowl out

Zero commission broker Robinhood is looking for funding. Even though revenues have reportedly tripled year on year, the broker urgently needs to invest in their infrastructure after well publicized service disruptions left many users out of pocket.

Comment: please remind me again exactly what problem Robinhood solves? My broker offers zero commission trades. And my broker doesn’t have service outages execution delays. This seems like another solution nobody really needs.
