Dear [SPONSOR CONTACT],

On behalf of everyone at The Open Source Initiative and the open source community, I would like to thank you for your very generous [YEAR] sponsorship of $[AMOUNT] received on [DATE: mm/dd/yyyy]. It is only through the generous contributions of people like you that the OSI can continue our important work to protect and promote open source software, development and communities, championing software freedom in society through education, collaboration, and infrastructure, stewarding the Open Source Definition (OSD), and preventing abuse of the ideals and ethos inherent to the open source movement.

In order to recognize [COMPANY NAME]'s gift, we would like to add your logo and a link to our promotional and marketing material, including our "Corporate Sponsors & Support" web page (https://opensource.org/sponsors). If you like, please send along a [COMPANY NAME] logo (high resolution png and vector image) and a URL we can point to, and we will add it to our website, brochures, posters, etc..

We would also like to share the good news with the larger open source software community with a press release. Can you please point me to the appropriate communications folks (if that is not you) at [COMPANY NAME] that I can work with to develop the announcement?

Finally, as a public charity under section 501(c)(3) of the Internal Revenue Code, our U.S. Federal Tax ID number is 91-2037395, which may be needed by [COMPANY NAME]'s accounting offices.

Thank you again for your sponsorship!

Sincerely,

Patrick Masson
