Sentinel's Mission is to Defend Democracies Against Information Warfare

Headquartered in Tallinn, Estonia, Sentinel works with governments, media and defence agencies to help protect democracies from disinformation campaigns, synthetic media and information operations by developing a state-of-the-art AI detection platform. The company was founded by ex-NATO AI and cybersecurity experts and is funded by world-class investors such as Jaan Tallinn (Co-Founder of Skype, early investor of DeepMind) and Taavet Hinrikus (Co-Founder of TransferWise). Our vision is to become the trust layer for the Internet by verifying the entire critical information supply chain and safeguard 1 billion people from information warfare.
