Tout has about 700 users, and about ~15 paid users @ $30, with a good number of people "waiting" for a lower priced solo plan. Braintrust has a higher number of users, but most of them are no longer active -- so I've stopped looking too hard until the re-launch.
Congrats on getting people to pay. The biggest surprise the first time that you create a product is how hard it is to even get anyone to use it frequently, let alone pay.
Right. I try to define and track atleast one metric that gauges how sticky and useful my products are. For Braintrust, I track # of edits, for Tout, I track # of emails sent.
