Brittany Kaiser worked for Cambridge Analytica for four years, rising to director of business development before leaving the electoral consultancy in January 2018. In March that year, she handed information about company activities to the Guardian newspaper’s Cambridge Analytica Files investigation, which had recently triggered the scandal that would destroy Cambridge Analytica and earn Facebook a $5bn fine. A month later she testified before the UK parliament’s Digital, Culture, Media and Sport Committee as part of its investigation into fake news. Brittany has subsequently been an expert witness for investigations into the data industry, big tech and elections around the world. In 2018, she co-founded the Digital Asset Trade Association, which aims to work with policymakers to enact favourable legislation around blockchain technology and digital currencies. She has also launched a Change.org petition, #OwnYourData, to reclaim personal data from Facebook.
