Alice, an AI security company known for its expansive archive of adversarial internet content, has raised $140 million in a new funding round led by Apax Digital Funds. The capital will power efforts to rigorously test and protect AI models from manipulation and malicious exploitation before and after deployment.
- Alice has catalogued the largest dataset of adversarial content since 2018.
- The $140M round values Alice near $1 billion, doubling total funding to $280M.
- Over 150 AI researchers work on proactive and post-deployment AI security.
What happened
Alice, a company specializing in AI security formerly known as ActiveFence, announced a $140 million funding round led by Apax Digital Funds, bringing total capital raised to $280 million. Apax Digital will also join the board, while new investors MoreTech, Phoenix Financial, Samsung Electronics, and SentinelOne participated alongside returning backers. The company’s valuation is estimated to be close to $1 billion.
Alice has developed an extensive dataset—named Rabbit Hole—that catalogs harmful, manipulative, and malicious internet content gathered over eight years. This dataset is now used to stress-test cutting-edge AI models by simulating malicious prompts and identifying vulnerabilities before models go live. Key clients include industry-leading labs such as Anthropic, Google, and Cohere.
Why it matters
The emerging gap between AI capabilities and security has raised concerns around vulnerabilities like jailbreak attempts, prompt injections, and unintended autonomous behaviors. Alice’s focus on adversarial testing is critical as enterprises deploy AI systems across high-stakes environments requiring safeguards beyond initial guardrails provided by AI labs.
By simulating attacks and monitoring live model interactions, Alice helps identify data leaks and compliance gaps that could lead to significant risks. Recent incidents involving models escaping test environments highlight the crucial need for specialized security solutions to prevent exploitation, underscoring Alice’s role in bridging this protection deficit.
What to watch next
Alice aims to grow its annual recurring revenue, which has already surged by over 500% in two years, while expanding its AI security research team, currently numbering more than 150 specialists. The company plans to deepen cooperation with remaining top AI labs and increase coverage across major platforms like Google, Meta, TikTok, and Amazon.
Industry observers will monitor how Alice’s security approaches influence AI development standards and shape enterprise adoption of AI systems. Additionally, the company’s ability to prevent costly breaches and malfunctions will be key to sustaining investor confidence and scaling global operations in a rapidly evolving AI threat landscape.
