May is Maintainer Month, when we celebrate the Open Source maintainers that make the software we all rely on possible. But we can and should do more than just celebrate, because the Open Source ecosystem we rely on is built on the too-often unpaid labour of these maintainers.
That's why we want to draw attention to the forward-thinking companies that pay the Open Source maintainers whose work they depend on, changing the Open Source ecosystem for the better. Open Source Pledge members have paid $2,650,212 to maintainers over the last year — and that's worth celebrating.
Last October, we featured 20 Open Source Pledge members on the big Nasdaq screen in Times Square.
And last week, we did it again.

The Open Source pioneers we're celebrating this time around are data science company Posit; CMS creator Sanity, who are powering the blog you're reading; Convex, who build reactive database technologies; API expert Speakeasy; Platformatic, who make tools for Node.js developers; brokerage platform and FLOSS/fund creator Zerodha; performance profiling experts Tideways; developer tool company Pydantic; JS package manager vlt; Python & Django codebase creator SaaS Pegasus; VoidZero, building next generation JS tooling; data grid creator AG Grid; and documentation generator GitBook.
We're also celebrating member company Foxley Talent, a recruiter with 17 years of experience in the Python and Django community — their logo should have been on the screen, but is missing due to a clerical error on our part.
Do you want to do something for Maintainer Month? We think the best way to show your gratitude to Open Source maintainers is to join the Pledge, and make the Open Source ecosystem you rely on safer and more sustainable.
