Alice Raises $140M to Protect AI Models

Alice announced Tuesday that it raised $140 million in a Series round led by Apax Digital Funds, bringing its total financing to $280 million. The company said the capital will be used to advance its AI protection platform, grow the team behind its intelligence dataset and scale commercial operations. Participating investors included MoreTech, Phoenix Financial, Resolute Ventures, Grove Ventures, CRV, Highland Europe, Vintage Investments, Norwest, NFX and Claltech.

Alice, previously known as ActiveFence, provides red-teaming and runtime protections for generative models. Ahead of public releases, its research teams run simulated malicious inputs and complex agentic tasks to expose erratic model behaviors and vulnerabilities such as prompt injection and jailbreak attempts. When models move into production, Alice offers continuous red-teaming and dynamic runtime guardrails so customers can enforce internal operational rules.

Customers can configure internal guidelines, run simulated breach scenarios and monitor system traffic in real time to detect suspicious activity. The platform relies on a proprietary repository called Rabbit Hole, a dataset the company says was built over nearly a decade by tracking digital fraud, ideological extremism and manipulation campaigns. Alice says Rabbit Hole helps detect and intercept hostile inputs aimed at exploiting generative AI.

The company operates a research facility staffed by more than 150 specialists who collaborate with major model developers to identify failure modes and close security gaps. Noam Schwartz, CEO and co-founder, explained, “There are infinite ways to break an AI, and you can’t defend against something you’ve never seen. 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.”

Alice is headquartered in New York and Tel Aviv. The company said it will use the new funding to expand technical capacity and commercial reach in the market for AI trust, safety and security services.
