About Alethea
Alethea helps organizations navigate the growing risks of information manipulation, digital deception, and online influence operations. Our mission is to equip teams with the clarity, foresight, and confidence they need to protect their people, reputation, and operations in an increasingly volatile information environment.
Our AI-powered platform, Artemis, uses advanced analytics and machine learning to detect emerging narratives and digital threats before they escalate—drawing from more than mainstream platforms, like high-risk forums, fringe platforms, and covert networks where threats often take root. Built by our team of world-class analysts, Artemis turns years of expertise into a powerful tool that surfaces what matters most and guides smarter, faster decision-making.
We don’t just tell you that there’s a problem—we help you understand what it means and what to do next.
