Transparent Corporates

We're making corporate data freely and publically available, to empower you to hold the right people in the corporate sector accountable when they do things that affect your everyday life.

Our mission

We want to make corporate data truly accessible, because we believe you shouldn’t have to pay for company information that should legally and legitimately be public. We’re interrogating data around corporate structures and the relationships corporates have with the state, shareholders and communities.

We're here to help

We can help you find the important corporate data you're missing. Just send us a data request.
