"A social work collaboration platform with emphasis in project management"
The generous team at Freedcamp offer their premium features free of charge for eligible non-profits and educational institutions/groups, pending an approval process.
Eligibility requirements are explained in more detail in the Freedcamp for Nonprofits FAQ and the Freedcamp for Education FAQ
When I worked in the disability sector in 2015/16 I found this and signed up. I used it within our department for our projects and was quite impressed with the platform. They claim on their website that AirBnb, Nike, Google, PayPal and other big corporations use their platform.
I like all the non-profits they exclude under Eligible teams.
If you're political, religious, discriminate, then bad luck.
