@clmorgan Analytics. We spent the better part of a year working on a custom analytics solution that our competitor had out in less than a month using a third party service that did 90% of what it needed to do.
Learnings from that for me: if in the early stages you can integrate third party solutions to add complementary features to your primary ones, do so.
@lizzielou We're building verbdata.com to make it way easier to set up customer-facing analytics. If you're in this phase of product development check it out.
I'm not affiliated with Contentful, but this looks really close (in fact I use DatoCms for static sites and that doesn't have approval workflows sadly).
