Superhuman is famous for not allowing new subscribers access to their product until they go through an hour long onboarding session with one of their team members. This provides them with the opportunity to show new users around and make sure that they know how to use the product correctly.
This can be really useful for early stage founders too—you may be worried that your onboarding experience is a little rough, so this gives you the opportunity to show users your product in a way that makes a great first impression.
Luckily, this workflow is really easy to setup with Outseta. Here's a video tutorial on how to set this up.
