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.

Why corporate data matters

We have datasets and have done work around tender information, beneficial ownership, company shareholder registries, illicit financial flows, potential conflicts of interest in the private sector, and the environmental and social impacts that the decisions corporates make have on everyday life.
