Hypothesis is a brand that is dedicated to annotating the internet and enabling conversations over the world's knowledge. Our mission is to bring content and conversation together through social annotation, creating universal collaboration across the entire web. Founded in 2011 by Dan Whaley, Hypothesis was born out of a need to enhance accuracy and elevate discourse in a world of distorted online information.

Today, we are pioneering the adoption of social annotation for education, research, business, and personal collaboration. What sets Hypothesis apart is our mission-driven philosophy and commitment to open-source principles and interoperable standards. We have actively contributed to the development of the web annotation standard through our involvement with the W3C Web Annotation Working Group.

We are also proud members of Invest in Open Infrastructure (IOI), dedicated to improving funding and resourcing for open technologies. Hypothesis is supported by Anno, a public benefit corporation, and funded by a $14M seed round. Our values drive our work, guiding us to always prioritize impact, remain customer-centric, and ensure our platform is universally accessible and unbiased.

We foster a moderated bottom-up community that allows for credibility without public identity, and we remain transparent about our systems and governance. Join us in making a mark on the internet.
