We just received an email that Guideline (401k provider) is switching to a model that charges a % of AUM.

A lot of their marketing was focused around charging flat fees rather than a % of AUM. I'm sure that our company is not the only one that chose to use Guideline for this reason.

In my opinion this change is extremely predatory and I wonder if this was their plan from the beginning. Does anyone have any suggestions on other 401k providers for small teams?
