Aspiration connects nonprofit organizations, foundations and activists with free and open software solutions and technology skills that help them better carry out their missions. We want those working for social and racial justice to be able to find and use the best tools and practices available, so that they maximize their effectiveness and impact and, in turn, change the world. We also work with free and open source projects and communities in both support and partnership roles, advising and contributing on matters of strategy, sustainability, governance, community health, equity and diversity. We design and facilitate unique and collaborative nonprofit and FLOSS technology convenings, and have run almost 800 in over 50 countries as well as online over the past 16 years. Our Strategic Development Program helps nonprofit leaders and fundraisers take a wholly new and empowering approach to revenue development, and our Policy Leadership Initiative supports emerging leaders in the European policy space as they demystify and engage with an opaque system.


DEF CON is a hacking conference started in 1993 that has grown and adapted with the times. With almost 30k people attending the event yearly DEF CON stays true to its core by sharing its content for free and operating services for the community such as the DEF CON Forums (now over 20 years operating), our Mastodon server DEFCON.social, Tor .onion servers and relays, as well as a discord.gg/defcon. People gather at DEF CON Groups around the world to share and learn. DEF CON believes in the power of the idea, how you conduct yourself, and not what you look like or how hard you meme. Supporting and operating services with Tor is an investment in a more open and accessible future. Get involved!
