Alice raises $140M led by Apax Digital as AI security business grows over 500%

The trust, safety and security firm, rebranded from ActiveFence earlier this year, sells adversarial testing and guardrails for AI models to frontier labs and large enterprises.

Alice, an AI trust, safety and security company, announced a $140 million funding round led by Apax Digital Funds. The raise, disclosed on Tuesday, lands as the company's AI security business grows by more than 500%, a figure that signals how quickly budgets are shifting toward tooling designed to keep AI systems in check.

Alice sells adversarial testing and guardrails for AI models, two capabilities that sit at the heart of operational AI safety. Adversarial testing is designed to surface weaknesses and failure modes in models before they can be exploited, while guardrails function as controls that constrain model behavior in live use. The company's customer base spans frontier labs and large enterprises, putting it in front of both the organizations building the most advanced AI systems and the businesses deploying them at scale.

The company's roots stretch back further than the current AI security boom. Alice began in 2018 as a trust and safety business, operating until earlier this year under the name ActiveFence. The rebrand to Alice marked a deliberate repositioning around AI security, aligning the company's identity with the product set it now sells to labs and enterprises.

The more than 500% growth in Alice's AI security business points to accelerating demand for exactly these capabilities, as frontier labs work to harden models against misuse and enterprises seek guardrails for systems they put into production. Apax Digital Funds' lead role in the round puts a major institutional investor behind that trajectory. For Alice, the $140 million injection arrives with the company already rebranded, already serving frontier labs and large enterprises, and growing its security business at a pace few categories in AI can match.
