Israeli AI security co Alice raises $140m
The company’s Rabbit Hole is a proprietary dataset of real-world adversarial and harmful content.
Alice, formerly known as ActiveFence, raised $140 million in a funding round led by Apax Digital Funds. The AI trust, safety, and security company specializes in adversarial testing and guardrails for AI models, targeting frontier labs and large enterprises. Established in 2018, Alice initially focused on trust and safety for consumer platforms, tracking fraud rings, extremist networks, and manipulated content.
Their data, known as Rabbit Hole, now serves as the largest dataset of real-world adversarial and harmful content, providing test cases for AI models. Over two years, Alice's AI business grew more than 500%, with annual recurring revenue nearing $100 million. The industry is facing a growing attack surface as AI capabilities are democratized before defenses are.
Alice's expertise, developed from a decade of watching people exploit technology, will help bridge the gap between model release and live use, where enterprise customers set policies and simulate attacks to ensure compliance and prevent data leaks.
