As a hub of European foundations engaged in the grantmaking for HIV and AIDS, the membership of EFG is comprised of European private funders with an office in Europe and individual philanthropic leaders.

While EFG cooperates with different HIV and AIDS expert and knoweldge generating organisations, only private funders may become full members of the Group.

EFG seeks to engage with bilateral and multilateral funders. Bilateral and multilateral funders can become associate members of EFG.
