Organizations enable a group of people to get a Blackfire Premium or Enterprise subscription.
If you need to use Blackfire with several persons on a common pool of machines, to share profiles, or to write performance tests and automate profiling, first create an organization and get a subscription.
You can start a free Premium trial as soon as you have created an organization. A same user can only start a single Premium trial on a single organization.
Organizations enable to have multiple projects with different subscription levels. They give more flexibility for companies working on several projects in parallel to tune the amount of users and environments for each project, the subscription level, and the billing cycle.
