They cost more. They charge .5 percent on assets vs betterment charging .15 if you have over 100k, and .35% if you dont.

They both do the same thing, tax loss harvesting and automatic rebalancing. That fee difference over 30 years assuming an investment of 20k per year and an 8% return could cost you like 400k - which is not chump change.

How do these compare to https://www.wisebanyan.com?

It seems to be roughly the same idea, but without any fees at all (I haven't used any of them, so I'm likely missing something)
