Former FA employee here: They're a great company. Grew about 45x while I was with them. They use BlackRock funds, so BR saw the growth. A pretty good ending for 5 years work. The Financial Times is reporting they sold for $150M-$200M.
I was an extremely early beta user of Future Advisor (I had reached out to Bo from an HN post), and I wasn't impressed after a long experience with them. It was a terrible process having my retirement accounts moved from fiduciary to fiduciary, having problems getting additional retirement contributions into the accounts, etc.
BlackRock is interesting in that they're very forward-looking and conservative at the same time. One of the first to use an AI-like system to support management of huge assets. Also one of the elite firms of the country in terms of just how much capital they manage.
