Who likes to use robo services? Are they just people with no money? Or millennials? Is that just two ways of saying the same thing? Or is there something else going on?
Turns out that the appeal of robo-advice (for investments, at least) is wider than just millennials, and the users of the service do have money. Higher proportions of women, particularly young women, use robo-advice. Also, higher proportions of Asians (and this data being US) Hispanics use robo-advice. Link.
