Open Source Investigation

Need help making sense of the sea of information available online? If it's accessible publicly, we can help. Our team of experts can share their knowledge about the intricacies of the web and find gold mines of information spread out in every corner of the internet. If it exists, we'll find it and help you make sense of it.


Check First is all about finding the best tool for the job. With an experience of 20+ years in software development, our team members will help you organise your data, foster collaboration among your team and help you showcase it to the public or your target stakeholders.


Data is cool. Making sense of it is better. Our strength is the complementarity of our team, coming from both the tech and the media world. Our research is aimed at understanding an issue, following a lead and performing investigations to stress what is relevant.


Accountability is a strong value of our company, and we wish everybody would be accountable. Check First has taken part in successful projects monitoring big platforms to provide researchers with data and make sure stakeholders are delivering what they promised.


Losing time is one of the most frustrating sides of collaboration. We aim at streamlining partnerships and internal work.
