Black Duck Open Hub provides analytics for Open Source projects, and has entries for organisations, found at https://www.openhub.net/explore/orgs , allowing a collection of projects and interesting analytics of affiliated and non-affiliated contributors to those projects, and also analytics of what non-org projects those contributors collectively also contribute to.
However I can not find the process to create an organisation.
There was a thread in the old forum system where people could ask for an org to be created, and occasionally someone at Black Duck would do a batch of them.
The new forum system at https://community.synopsys.com/s/black-duck-open-hub seems dead and I don't see a similar thread.
