We support Open Source.

As a 501(c)(6) nonprofit fiscal sponsor, we provide the financial and legal infrastructure for thousands of open source projects. We’re the 'API' between open source communities and the world of accounting and invoices.

Need a legal and financial home for your open source project?

Here’s how we help…

Open Source Projects

We handle the accounting, taxes, invoices, contracts, employment, and more for 3,500+ open source projects worldwide.

You’ll stay in control of your project, and we’ll make the operational details behind the scenes.


Companies and Organizations

Looking to support the open source projects your business depends on?

We'll help you find your core projects to back, provide valuable metrics, handle grants, and follow your accounting and legal requirements.

Open source is about cooperation and transparency.

We use the Open Collective platform to manage the fundraising and expenses for each of our fiscally hosted open source projects. This means all budgets are open and visible to everyone and the balance of each project is available in real-time. Even ours.

Here’s our budget.

We work in the open. Our staff is available via email, Slack, or 1:1 over video to help with any questions. We offer regular updates to our hosted collectives through the Open Collective platform and community calls.
