Our mission is to promote a sustainable and healthy open source ecosystem and work for the common interests of those who create and use open source software.

Companies get huge value from open source. But up to now, it’s been hard to give back financially unless a project formed its own foundation. Now they don’t have to. The Open Source Collective is a non-profit umbrella organisation providing financial and legal infrastructure for thousands of open source projects. It’s an API between the world of distributed collaboration and the world of accounting and invoices.

Please read our Terms of Fiscal Sponsorship and acceptance criteria.
