Bryan Bogensberger (CEO of npm) writes on npm blog:

Over the past couple of years, we’ve observed a number of models emerging that enable a path towards sustainability for Open Source maintainers. Most notably: OpenCollective & GitHub Sponsors. We at npm are in full support of both these initiatives, and intend to collaborate further with these organizations.

Now we are ready to invite the community’s most active contributors and the biggest enterprise consumers of public open source code to a working group to finalize the platform’s definition.
