Here’s the FSRankings ranking of robo-advisors based on average account size. A single person could have multiple accounts (e.g. if you have an IRA and a college 529 savings plan), so there may be fewer actual customers for each robo-advisor.
AssetBuilder has by far the largest average account size, with over $270,000 invested per account. On the other end, Acorns’ focus on “micro-accounts” leads it to have by far the smallest average account size.
