We make software to store, share and annotate media for educators and creators.

Our core product is a collaborative media annotation system, Music Circle. You can upload, annotate and share time based media such as audio and video. You can use it as a standalone platform or we can integrate it with your virtual learning environment.

Examples of people who have used Museifi technology:

Caroline Welsh, Music Junction, workshop leader, London Chamber Orchestra:
We could straightaway see that the Music Circle project was a good fit for our outreach programme, Music Junction at the London Chamber Orchestra.

A Goldsmiths music student discussion MusicCircle:
I found that the most valuable part of this activity was connecting with other musicians on a more critical level. We were no longer just listening and enjoying, we were giving advise and tips on how to better each other as musicians.

Dr Chris Kiefer, Lecturer In Digital Humanities (Music), University of Sussex: MusicCircle gives us an ideal environment for our electronic music students to share and give feedback on each others work.

Ed Jones, explaining why he chose to use Music Circle in his Jazz Performance in Context mpdule:
I firmly believed that Music Circle would not only be an effective way of documenting the information disseminated during the sessions and act as a reference space for this, but also a tool by which the students could develop perceptions of their own artistic process in a multitude of ways.

From the commissioning artist for the Wellcome Trust funded insstallation, Chorus:
Can i just say a thank you for building such a robust and reliable system for chorus. I am impressed, and obviously very pleased that it's running with very few faults. The ability to monitor remotely obviously fantastic too.

Museifi's media storage technology is being used to build a new online Museum, the Museum of Sound, in collaboration with Matthew Herbert.


Museifi was spun out from Goldsmiths in Autumn 2015. It is based on the “Music Circle” Intellectual Property developed as part of the PRAISE project of which Matthew Yee-King was the lead architect and Mark d’Inverno was the principal investigator. PRAISE developed software which enables students and users to upload creative time-based media (such as music and video) to invite comment and review by others in their community. The Museifi suite of products (using the software developed in PRAISE) wraps up this functionality allowing it to be used commercially in both educational and other collaborative environments.

Museifi is jointly owned by the executives of the company and Goldsmiths.
