I'd be pretty worried if I was one of the new "robo advisor" startups, quoted only because I can't think of a better name for them.
1) By definition you're a passive investor so you don't provide any service that can't be replicated by the big players in a very quick manner.
2) you don't have any where near the economies of scale as the big players so when this becomes a fight to the bottom to lower management fees you'll be the first to lose.
3) Your going to put your clients money into funds run by the big players so even if you pull money from the big players you are helping your biggest competitors by investing back into them.
I can't see anyway this isn't head Wealthfront loses tails vanguard wins.
Couple that with the possibility of VC money starting to dry up and you've got to ask, if Wealthfront and Betterment receive no more VC money from today onward are they ready to fight head on with companies 2-3 orders of magnitude larger than themselves who can afford to keep lowering fees for years to come.
Can someone here make the case why anyone would chose to invest with these new companies rather that Vanguard or Charles Schwab?
