Yes, I have, thanks to OpenCollective. (see https://opencollective.com/react-boilerplate)
Historically, donating money to open source projects has been hard for companies, as donations can be written off but only with a legal entity behind the receiver—and which open source project has a legal entity behind it except for the very biggest?
OpenCollective solves this exact problem. They have host companies all around the world, so both users and companies can donate to open source projects without problem, and they'll get their logo in the READMEs of popular project as a return for their help.
It's also fully transparent, meaning everybody can see exactly where the money goes, and contrary to Patreon works perfectly for teams. (whereas Patreon only works for a single person)
Sorry for the rambling answer, but I'm super excited about OpenCollective and how it finally enables us to create sustainable open source projects.
