Ways to Give

Thank you for your interest in supporting COS. We are grateful for the generosity of the open science community in support of our mission.

As such, we ask that our donors also are transparent in their support of COS. If you prefer to remain anonymous, we encourage you to direct your contribution through a third party. You can give directly and anonymously to COS via PayPal Giving Fund, Network for Good, or major donor-advised funds.

Our business model

COS has implemented a sustainability model for maintaining an open-source, public goods infrastructure by partnering with stakeholders in research, including funders, federal agencies, research institutions, and individuals.

As COS has evolved from a small, start-up organization to become an established pillar of the open science movement, we have worked to garner philanthropic support from individuals, particularly researchers, who are similarly committed to supporting free, public, and accessible data.
