In cruising around I found this very interesting mutual fund company. Short story: they run a coupe mutual funds where you get to pick whatever fee you want to pay them. It is a bold move to build a business on trust — a move that more people in the should be making IMHO.
Here are my only caveats:
They have two funds, which both look great — but are fairly specialized. Which means they should be used in conjunction with other things (like a passive index strategy). But since you can, currently, only get access to the Aspiration funds on the Aspiration platform it means you'll have to have other accounts (making life more complicated).
I actually had the opportunity to meet the design team behind Aspiration recently and I expressed this concern. They were a great group and definitely heard the issue. Hopefully they are working on some more features! But I will keep you posted.
