Hypothesis is a small nonprofit pioneering a key new capability for the web called Web Annotation. We were instrumental in the development of the W3C Web Annotation standard, and are the creators of it’s most comprehensive general purpose implementation. We are working with publishers, educators, journalists, and scientists to bring annotation to the web at scale.

We are a diverse, supportive, highly collaborative, 100% remote team of technologists, and discipline experts . We code in the open (our repos are public and liberally licensed) and also work within the standards process. We work collaboratively via Slack, video conferencing, GitHub, and Google Docs across 8 time zones. Our team is based in the US (San Francisco, Portland, Chicago, New York and others) and in the UK (Edinburgh and Cambridge).
