Tidelift is a company that offers subscription services for companies to get development support for important open source; the company has raised $15M in funding to build out these services.
From the article:
The company wants to sign up independent developers working on core open-source projects as “lifters,” or ongoing maintainers of a given project, who will get paid for their contributions to open-source projects being tracked by Tidelift.
It will also sell a subscription service to software-development teamsusing open-source projects that gives them the confidence that a paid developer will be working on bug fixes and security issues related to their key projects.
The company will split about half of the subscription revenue with developers that sign up for their program.
