New Vision Statement:

The InnerSource Commons is a thriving community that empowers organisations and people worldwide to apply and gain the benefits of open collaboration in their internal work.

New Mission Statement:

We empower developers and organisations to apply open collaboration principles in their daily work.

We are the neutral hub and central collaboration space for InnerSource knowledge. As such, we maintain our independence and operate on a lean budget.

We build a strong, inclusive community and industry partnerships. Together, we apply open collaboration principles to drive the conversation about InnerSource and steward the InnerSource body of knowledge.
