Alice Secures $140M to Harden AI Models Against Adversarial Attacks

AI trust and safety company Alice, formerly operating as ActiveFence, announced a $140 million funding round this week, bringing its total capital raised to $280 million. The round was led by Apax Digital Funds, with participation from MoreTech, Phoenix Financial, Resolute Ventures, Grove Ventures, CRV, Highland Europe, Vintage Investments, Norwest, NFX, and Claltech. Headquartered in New York and Tel Aviv, Alice plans to use the fresh capital to scale its go-to-market efforts, expand its research division, and further develop its proprietary AI defense platform.

The company partners directly with AI developers to stress-test foundational models before public release, executing mock malicious inputs and complex agentic tasks designed to expose erratic behaviors such as prompt injection and jailbreak attempts. Once models move into production, Alice provides continuous red-teaming and dynamic runtime guardrails that align operations with custom enterprise business rules. Organizations can configure internal guidelines, simulate breach scenarios, and monitor system traffic in real time to ensure compliance with evolving security policies.

Central to Alice's offering is Rabbit Hole, a proprietary intelligence dataset built over nearly a decade by tracking digital fraud, ideological extremism, and manipulation campaigns at scale. This repository enables the platform to detect and intercept hostile actions targeting generative AI systems. The company also operates a dedicated research facility staffed by more than 150 specialists who collaborate with major model developers to identify failure modes, analyze manipulation vectors, and proactively close security gaps. As enterprises increasingly deploy AI across critical workflows, securing these endpoints becomes as essential as running a routine privacy checkup or validating infrastructure with an SSL/TLS checker. For organizations concerned about broader exposure, an email breach checker can help identify whether employee credentials tied to AI pipelines have already surfaced in known leaks.

"There are infinite ways to break an AI, and you can't defend against something you've never seen," said Noam Schwartz, CEO and co-founder of Alice. "We spent nearly a decade learning exactly how people abuse technology at the scale of billions, first on the world's largest platforms and now on the models those same people are probing. We are very quickly democratizing capabilities before we've democratized the defenses. This round is about closing that gap." The funding underscores growing investor confidence in dedicated AI security infrastructure as adversarial techniques targeting large language models continue to proliferate across enterprise environments.
