There has actually been a ton of overlap code-wise. Also, we wanted to be able to cross-promote the products which has worked incredibly well, building both audiences simultaneously. Most of our focus is on Minimalytics, but HookFeed is moving very quickly as well due to the overlap.
I would recommend it if the two products are similar.
Also, we have the choice to context-switch and work on what we are most passionate about on any given day.
