FWIW, there seem to be a two broad categories I’m seeing:
General info radiators
These usually take the form of ultra-customizable widget-based dashboards that can take input from a lot of different sources.
FWIW I did a trial of Klipfolio and I’ve been impressed with the level of depth in it. Particularly the fact that it’s possible to connect it to pretty much anything that has a RESTful API without writing any code.
These plug into Stripe, Recurly, or one of a few other subscription payment processors. They are focused strictly on deep financial analytics, starting from MRR and getting more detailed from there.
I’m thinking I’m probably going to wind up picking one from column A and one from column B - the dashboards seem nice for keeping track of more than just financials, but none of them dig as deeply into financials as the finance-focused products.
