About the project
The Aleph data platform brings together a vast archive of current and historic databases, documents, leaks and investigations.
This web of evidence helps journalists at OCCRP, other publications, and across the world, to see connections, find stolen funds, spot political influence, and unveil corruption.
As part of Aleph, we periodically fetch public records from over 230 online sources, and provide a public search access. Accredited journalists can also access an archive of leaked evidence.
