If you work for a company with a corporate donation matching program, you can effectively double your impact in many cases.

Microsoft employees should use the portal to donate so they can take advantage of this amazing opportunity.

Donations go towards our overhead and our ability to support developers with the tools they need to work effectively in Open Source.

Digital Defiance board members are currently volunteer and do not receive any compensation.
