The MXM Society is a community of EFF members whose annual donations are $10,000 and above or have given more than $100,000 in their lifetime.

Generous support at this level ensures that EFF can use its decades of unique expertise to ensure that whenever threats to civil liberties arise, technology users everywhere can count on us to defend them.

EFF was founded in 1990 to fight against injustice and stand for freedom. Thirty years later we’re still standing, and taller than ever before. The MXM Society celebrates this long legacy while working to ensure that EFF remains strong for decades to come.

As an MXM Society member, you’ll allow EFF to be flexible to meet the moment, with a focus on cutting-edge programs developing freedom-enhancing software, educating technology users about pressing issues, and carrying out incisive legal work in the public interest. This level of support allows us to jump into action and act immediately wherever digital civil liberties need a defender, whether it's responding to the latest attack on encryption, responding to a national emergency, or taking on a new bully.

In recognition of your leadership and commitment to EFF’s mission, you’ll receive:

  • Access to invite-only MXM Society events
  • Quarterly ‘Insider Briefing’ updates
  • Personalized EFF swag pack including the latest member shirt – just let us know what you’d like!
  • Invites to EFF general member’s events, such as member Speakeasy
  • A keepsake metal member card - personalized with your name

With your support, we have the ability to build a better future for civil liberties online and human rights for all. Thank you for considering joining this movement. Donate here to join today!
