About us Image

Mozilla Data Collective is a mission-locked British company, incubated by Mozilla Foundation and backed by the not-for-profit Mozilla.org.

We are the collective of technologists, linguists, researchers and creatives who want AI to be all it promises to be - not all it threatens to be.

Whether you're a tech start up, library, archive, or global non-profit, we want to enable you to share your datasets in line with your mission and values.
