all you are going to deduce from this is whatever you put into your model. if they were getting exponential growth then most of the calls would have been recent. and they imply that they had viral growth because use was spreading...

on the other hand, presumably they didn't decide to fuck over a bunch of grannies for fun (even if they did go to palantir). so it was an acquihire. so maybe some part of the description was more positive than the unvarnished truth?
