Google's model might work for us: they give away a lot of resources for free and help a lot of people, and they charge certain segments of their audience that can afford to pay. So while people are accustomed to paying advisors for a plan, we think it's better for our audience and a competitive advantage to be free.
There's other ways that people are accustomed to paying advisors now that could work. For example commissions on insurance sales. The price of insurance is fixed by regulations in the U.S., so you pay the same price regardless of where you buy it; might as well buy from us and get a free financial plan too :-)
Another company tried charging for plans, but that didn't seem to work, they've since changed their model. We think it'll be better for our customers and for us if the financial services companies pay for this somehow.
