## How to apply

Please note that we have a limited number of openings for OSS sponsorships each month. If you're interested in applying for a sponsorship for your open source software project, please follow these steps:

* Ensure that you meet all the sponsorship criteria mentioned above.
* Send an email to [peer@cal.com](mailto:peer@cal.com) and explain what you are working on and confirm that you meet all the sponsorship criteria (watch out, Peer may invest a small angel check in your COSS company 👀)
* Explaining why Cal.com's free tier or open core is insufficient for your project
* Include your Cal.com team slug and provide a link to your open source repository in the email.

<Note>
  Please note that sponsorship requests are reviewed on a monthly basis, so allow some time before reaching out for updates. We reserve the right to reject any project at will without reason.
