Really like this. Even the cheapest robo-advisors like Betterment charge 0.1-0.3% on top of the fund fees, which sounds small but eats into gains over time.

However, I think the target audience is probably more likely individuals rather than financial advisors, unless you're going to be running it as a SaaS. I can't see the overlap of small advisory firms and those familiar with Vagrant.

Will give it a poke with a few hundred dollars in Vanguard ETFs.
