Money by month, last five years. First money received in Apr 2018. The typical month is the median: one big one-off donation does not move it.
The same collective is named by 3 more tools in our catalog: Celery, Kombu, amqp.
Open Collective lists this collective for the celery organization on GitHub, so the money is for all of its projects, not Billiard alone.
