+title: New sponsoring tiers
+summary: We refurbish the tiers to provide more to our sponsors

+
+We made several changes to the sponsor packages offered on the [OpenCollective sponsoring page](https://www.opencollective.com/crystal-lang).
+
+The sponsoring tiers and their perks hadn't been updated in a while and we felt it was time to freshen up.
+Particularly, we want to offer more differentiated opportunities for expressing thanks to our sponsors.
+
+The general structure of tiers hasn't changed. It's a bit more refined now with clearer naming.
+We consider three groups of sponsorship levels with different target audiences:
+
+1. **Backer:** Individuals and small organizations who love Crystal and want to support it.

+2. **Sponsor:** Individuals and organizations who want to support Crystal and maybe gain some visibility.

+3. **Corporate:** Organizations who want to support Crystal and obtain support to move their business forward.

+
+There's also an open donation tier for a one-time contribution or continuous support at a value of your choice.

+
+The thresholds for the individual tiers stay mostly the same. We thinned out some intermediary tiers that were barely used.
+
+Most relevant changes:
+
+1. Backlinks from the [Sponsor page](https://www.crystal-lang.org/sponsors) are available at the *Backer L* tier ($25).
+2. New options to improve visibility of sponsors:
+  * Logo and link in the [release posts](https://crystal-lang.org/blog/#release_notes) at *Silver Sponsor* ($350)
+  * Logo and link in the [newsletter](https://crystal-lang.org/#newsletter), [README](https://github.com/crystal-lang/crystal/blob/master/README.md), presentations and other communication materials at *Gold Sponsor* ($750)
+3. Sponsor logos on the [homepage](https://www.crystal-lang.org) are shown in two different sizes:
+  * Small logo at *Silver Sponsor* ($350)
+  * Big logo at *Gold Sponsor* ($750)
+4. Directed Corporate Sponsors to contact us to better tailor a package that suits their needs.
+
+Everyone who is already a sponsor stays in the tier that corresponds to their current monthly contribution.
+Some of the perks in that tier may have changed. We understand this is a breaking change.
+If this affects you, please let us know at [[email protected]](mailto:[email protected]).
+
+The new perks will take a couple of days to take effect.
+
+The Crystal project depends on your support and we're grateful
+for any contributions that help the development of the language and its ecosystem.
+Thank you to all the sponsors who have made Crystal grow and continue to do so ♥️
