 ## A list of companies that sponsor open source software
 
-##### Feel free to send a PR to update this document.
+**The goal of this list** is to highlight companies who pay back to open source projects that are helping them to save time and money. Open source maintainers are often an invisible and underfunded workforce behind our informational infrastructure. With this list we would like to encourage more companies to be aware of that and play active role in supporting our common grounds.
 
-##### Requirements: (1) it is a company (for instance, you hire developers other than the company owners) and (2) it sponsors open source projects (e.g. through OpenCollective, Patreon, direct donations or time for employees).
+##### Feel free to send a PR to update this document.
 
-##### Each company should: (1) have a name, (2) have a link to blog post or page demonstrating that you sponsor some open source projects or employee hobby projects.
