About the Thunder Coalition
What is the Thunder Coalition?

Industry partners, publishers, individuals, implementation partners and the core team form the Thunder Coalition. The goals of the coalition are

  • to enable publishers to deploy rich functionality for their products very quickly and at reasonable cost,
  • to share functionality among publishers, driving the industry and providing excellent user experience with the individual content,
  • to enable industry partners to spread their outstanding services amongst publishers and to charge for premium services as the publishers grow,
  • to enable implementation partners to gain knowledge about Thunder programming and implementation in order to provide services to publishers and industry partners.

How does the Coalition work?

The Coalition discusses feature requests and offers, celebrates new launches, and is a platform for programmers and executives in the publishing industry. There is mailing list, a Slack team, and we’re planning to have regular Coalition meetings in the future.

Back to questions
What about the industry partners?

Industry partners may add functionality to Thunder, provided that this functionality is useful for publishers, free of charge for unlimited time and that the industry partner is invited and/or accepted by the Core Team.

Back to questions
So Thunder re-sells industry premium functionality to publishers?

No. If a publisher wants to procure premium functionality from any industry partner, the Thunder Coalition is not involved. Any contract is established directly between the respective industry partner and the publisher.

Back to questions
Why would an industry partner join?

The Thunder Coalition offers industry partners to have their software or services used by many publishers. The industry partners may also offer additional premium functionality, which publishers might want to use and also pay for.
