Slack giving $$ back in exchange of knowing better their users

Slack’s growth in terms of active users is one of the highest in the last years, even if you compare that with the impressive figures for instance from Facebook or Airbnb . Perhaps for this huge growth they are trying to understand more about how people use it, how they interact with it in their day to day tasks… giving you the option to tell them more about it during your onboarding process (in exchange for Slack’s credits).
