It was last February that ESLint started accept sponsorships for ongoing maintenance and development. Since that time, we were able to hire our first dedicated maintainer, Kai Cataldo. Kai's focus has allowed the project to regain some momentum and improve responsiveness to issues, pull requests, and RFCs.
Additionally, having a dedicated maintainer has allowed us to add a new platinum level of sponsorship at $2000/month. Platinum sponsors not only receive top billing on eslint.org, but also receive two hours of support from the ESLint team each month. That's support to help set up ESLint, write custom rules and plugins, work through integration issue...anything you need.
In the next year, we'd like to bring on a second dedicated maintainer, and we need to reach a sustained amount of $10,000 per month in donations to do that.
If your company is in position to consider platinum sponsorship, we'd greatly appreciate your consideration.
