J and I just gave to the Ada Initiative and there are a lot of things about their fundraising process that is well done. I’m sharing it here as inspiration/ideas to steal for Mach 30:
Twitter stream is full of reasons to support their work with Retweets, photos, everything. All of it geared toward the cause, not the organization: https://twitter.com/adainitiative
Website includes specific asks to help spread the word–including sample social media posts: https://adainitiative.org/how-you-can-help/spread-the-word/
Site lists concrete ways people can support the mission of the organization with or without giving money: https://adainitiative.org/how-you-can-help/
Donate page makes it easy to give, has unique funding levels, and includes short, powerful reasons to support the initiative: https://adainitiative.org/donate/
Provides easy ways for supporters to do matching campaigns. Here’s an example campaign: http://bookmaniac.org/make-hackerspaces-better-support-ada-initiative/ –It’s not clear to me how you start a matching campaign which is less good, but that might be because they are nearly done with their drive.
Also, great blog posts: http://adainitiative.org/
In general every page makes a powerful argument, but is also very short and to the point. There is no slogging through text to get to the “give us your money” part, but it also doesn’t feel like “give us your money because I said so”
