The Team

OpenSanctions is a small business that develops the open source technologies and the database they produce. Our team is as passionate about producing high-quality data as about fighting financial crime.

Friedrich Lindenberg is the founder of OpenSanctions. His interest in watchlist data is inspired by his work in investigative reporting. Friedrich led the data team at the Organized Crime and Corruption Reporting Project (OCCRP) from 2016 to 2021, where he contributed to numerous investigations into transnational crime, offshore finance and money laundering; including the Russian and Azerbaijani Laundromat cases.

He started the Aleph project, an open-source data platform used by reporters and analysts in over 40 media organisations to explore large structured and unstructured datasets and find reporting leads.


Frederik Richter worked as a financial and investigative journalist for 20 years, during which he uncovered numerous cases of fraud, money laundering and bribery. His main interest has always been the space where power and money overlap.

Frederik reported from the Middle East and South East Asia for over ten years, including for Reuters. In 2015, he joined the Berlin-based investigative newsroom CORRECTIV where he led a number of award-winning investigations, including on the global CumEx tax fraud. In 2020, he published a book on the foreign corrupt practices still widespread in the export business of German industry, with chapters including on Brazil, South Africa, Russia and the Arab world.
