This looks very cool - but I'm hesitant to sign up without knowing how you make money. Is it PFOF? Transaction fees? Flat fee?
I'm not interested in investing my time and money getting onboarded with a service unless I know the long-term fees are going to be amenable. If it said something like, "$15/mo and free for the first year" I would be on board.
For example, Guideline. They charged fixed fees on employer 401k accounts , until they didn't earlier this year.
