Company Overview

Whisper is an Amsterdam-based cybersecurity company founded in 2024 that is developing a platform to shift security from reactive to predictive. The company's technology uses knowledge graphs to provide a comprehensive, "God Mode" view of the internet, enabling users to anticipate and predict cyber attacks before they can cause damage. After launching in January 2025, Whisper raised €1.6 million in a pre-seed funding round in July 2025, led by Atlas AI^VB Fund I, to support its expansion into Europe and the United States. The platform is designed for cybersecurity providers, government agencies, and enterprises to detect coordinated threats and manage cyber risks more effectively.
