We are a registered 501(c)3 charitable organization. We feel strongly that this structure best suits our vision to make open annotation a reality. It aligns our interests with those that directly benefit from what we do.

Our long term strategy is one of revenue sustainability. As a non-profit, many venture financing options are unavailable to us, so your contributions help greatly. We are so grateful for all the support we’ve received from our sponsors.

Please consider making a donation. All contributions are tax deductible.
