Apply to add your charity or nonprofit to 21

A 21 public profile is a replacement for a public email address. It allows people to charge a fee for others to contact them. They can then keep the fee or donate it to a good cause.

Perhaps they could donate it to your good cause!

Here's what a 21 profile looks like:

To see it in action, take a look at this tweet by Ben Horowitz, cofounder and General Partner at Andreessen Horowitz. With 21, Ben was able to sell a few minutes of his time to fund Black Girls Code. It's like a more convenient version of Warren Buffett's annual charity auction, where he sold an hour of his time for $3.5M.

There are a variety of good causes that people want to support with their time. If you want to raise money for your nonprofit or charity with 21, please answer the following questions and we will be in touch soon!
