Haiku, Inc. Now Accepting Donations Through GitHub Sponsors

News posted on Mon, 2022-07-11 17:00

We are proud to announce that Haiku, Inc. is now accepting donations through GitHub Sponsors. This was actually set up about a month ago but it was only announced in our forums. We already have 10 sponsors and have set a new goal to get 20. One nice aspect of GitHub Sponsors is that the fees for any payments are covered by GitHub. Haiku, Inc. loses a decent percentage of our PayPal donations to fees, so any current donors using PayPal to donate to Haiku can consider switching to GitHub Sponsors to make your donation go a bit further.
