Lighthouse Reports is a non-profit based in the Netherlands that leads complex transnational investigations blending traditional journalistic methods such as freedom of information requests with emerging techniques like open source intelligence and specialisms like data science.

Our collaborative newsrooms pioneer new formats and pay particular attention to fresh ways of framing complex issues that will capture public attention and challenge misconceptions. We believe investigative journalism helps people navigate complexity, so we create spaces to make this happen.

We follow the journalism code of practice as formulated by The Fourth Estate. It recognizes three core principles that are fundamental to the ethical practice of journalism:

– Reporting the truth

– Ensuring transparency

– Serving the community
