I love it! I wish more SaaS will provide such abstraction for users who only want a preview of all features. I find silly trial periods a quite waste of resources (storage, mailing cost etc.). When I am testing a new product I use test/fake data (e.g. temporal/masked e-mail address) and there is near-zero chance I will convert to paid account with it. I would rather create new account to drop all testing history behind me.
Congratulations, and I hope you will cut some pie from this crazy Jira-like-software market cake!
