" Investiguer sur les Publicités Politiques sur Facebook" ( - Investigating Political Advertisements on Facebook), par/by Manuel Beltrán and Nayantara Ranganathan

Our Exposing the Invisible (ETI) team was awarded a European Commission (DG CONNECT) grant under the 2019 Call for Proposals on Media Freedom and Investigative Journalism - “Action 3 - Pilot Project: Supporting investigative journalism and media freedom in the EU,” along with four other projects. For one year, between September 2020 and August 2021, we will organise activities for investigative journalists, citizen investigators, activists, researchers and others in EU member states to receive training in safe online and offline investigative techniques and tools, training of trainers and high quality self-learning and training resources. A particular focus will be on areas and communities where independent investigative journalists, civil society groups and citizen investigators have less access to skill sharing and networking, and where opportunities for cross-border and cross-discipline collaborative investigations are under-resourced or at risk.

This application is now closed - Join us for a three-week online workshop organised by Tactical Tech in November-December 2020 or January-February 2021 to work with civil society investigators across the European Union to enhance and share skills and techniques for secure investigations and digital research methods. We will explore new topics, address existing challenges and work together to develop new investigation resources and training curricula that you can take away and use in your own context.

This call for applications is now closed: 11 December 2020 (midnight CET). - We are extending the applications deadline to our "Exposing the Invisible" Investigative Institute taking place on 25 January - 12 February 2021.

Staying safe and aware is an integral part of any investigation. When embarking upon an investigation, the safety of your sources and collaborators, your own safety and the safety of your data should always be a priority.

An introduction to company investigations, related techniques and useful databases.

2019 was an exciting year for Tactical Tech, with highlights including the launch of 'Exposing the Invisible: The Kit', a three-week exhibition of The Glass Room in San Francisco, a redesigned and updated 'Data Detox Kit' in ten languages, and the release of the 'Personal Data: Political Persuasion' guidebook by our Data & Politics team.

We are translating The Kit so that more citizen investigators can use it.

Following our "Investigation is Collaboration" conference in August 2021 - and in order to leave a useful collection of long-lasting resources as legacy - we curated a digital booklet including an invaluable list of cases and best practices that arose from the conference discussions, memorialized here for everyone to access whenever, wherever. We hope you’ll use them to keep the conversations and collaborations going!
