Woohoo! As a registered non-profit, you're eligible for a 75% discount on all Trello products!
The Fine Print
Atlassian Community Licenses are designed for registered non-profit charitable organizations and charities which are non-government, non-academic, non-commercial in nature, have no religious affiliation and that would not otherwise be able to afford Atlassian software. If your organization does not really fit into this description, we suggest you purchase one of our commercial licenses – they are still highly affordable.
What do I need to do?
To get set up, reach out via https://trello.com/contact with documented proof of your non-profit 501(c)3 status (or regional equivalent), and we'll get that discount applied. You can do this before or after subscribing!
