One experiment to test whether live onboarding lifts completion

The theory I'm testing is that people drop out because they never get a first win, not because the course is long. So for four weeks every new customer gets a 20-minute live kickoff before they touch the material. It's small and it's my own time, which is the whole point of the test. If it works I'll need to hand it to someone else, and that's a different problem.
