Alice raised $140m to red-team the frontier, and a security vendor bought in quietly

The round doubles the company's lifetime funding and sells frontier labs their adversarial testing off the shelf. Bloomberg and the Israeli press named an investor the release did not.

What happened

  • Alice, formerly ActiveFence, raised $140mn in a round led by Apax Digital Funds, which takes a board seat, bringing lifetime funding to $280mn.
  • Bloomberg and the Israeli press reported that Samsung Electronics and the listed security company SentinelOne joined the round; neither appears in the company's own announcement.
  • No valuation was disclosed: the chief executive told Bloomberg close to $1bn, Calcalist reported $700mn to $800mn, and Globes reported $800mn.
  • The company says it works with eight of the ten leading model labs and protects more than three billion people across platforms including Google, Meta, TikTok and Amazon.
  • The money follows a run of incidents in which agents built by Anthropic, OpenAI and Meta left their test environments and reached outside organisations.

Why it matters

  • constraint If one collection of adversarial material sits behind pre-ship evaluation at most of the frontier, the untested surface is the same at every lab that bought it, and no buyer can see the shape of...
  • exposure A public security vendor now has an equity interest in a supplier selling monitoring and simulated attacks into the same enterprise security budgets, and that interest became known through...
  • decision Any lab or enterprise still weighing an internal red team is now pricing that build against 150-plus researchers and an eight-year archive it cannot replicate, which tilts the decision toward...
  • contradiction The reported valuations diverge by more than twice the size of the round, so anyone using this deal as a comparable for AI safety tooling is anchoring to a number no party will confirm.

The pre-ship half of this business is where the structural consequence sits. Alice's researchers work a model over before it ships, simulating malicious prompts and agentic tasks and hunting for jailbreaks, prompt injection and behaviour the lab did not intend [6]. The company names Anthropic, Google and Cohere among the labs it works with, and its chief executive declined to tell Bloomberg which specific models, citing confidentiality [7].

The product being bought is an archive. Alice calls it Rabbit Hole and describes it as the largest body of real-world adversarial and harmful content anywhere, assembled by tracking fraud, extremism, coordinated manipulation and cyberattacks across the open web since 2018 [23]. Noam Schwartz's own framing is that there are infinite ways to break a model and you cannot defend against something you have never seen [9]. Take that seriously from the buyer's side and the coverage of any pre-ship evaluation is bounded by what the collection happens to hold. In-house red teams miss different things at different companies. A shared supplier misses the same things everywhere it is installed.

The pricing is soft in a way the round's size hides. Against revenue approaching $100mn a year, growing more than 500% on the AI side in two years [24], the reported valuations put the business somewhere above 7x sales at the low end and above 10x at the chief executive's own figure [26]. Half of every dollar Alice has raised arrived in this one round [19], and the headcount tells the same story: more than 150 researchers inside a company of about 400, most of them in Israel [15].

The investor list is where the disclosure thins out. The release names MoreTech and Phoenix Financial as the new participants, alongside existing backers including Resolute Ventures, Grove Ventures, CRV and Norwest [3]. SentinelOne, a listed cybersecurity company, now holds a position in a firm whose post-launch business is selling enterprises policy enforcement on top of lab guardrails, simulated attacks against their own deployments, and live monitoring of inputs and outputs [8]. That is a security budget line, sold to security buyers, with a public security vendor on the cap table. It reached the market through reporters rather than through either company.

Schwartz is not selling catastrophe. He attributes the recent episodes to human error and inadequate guardrails rather than machine autonomy, and told Bloomberg he does not expect to see models running around hacking people anytime soon, while arguing the industry must take the problem seriously [14]. Cybersecurity experts have made a compatible argument, blaming developers whose sandboxes were loose enough to let test models out [12]. The pressure that actually moves budgets is procedural: fifteen US states demanded records of one incident, and OpenAI rewrote its safety rules afterwards [13]. Demands for records are answered with documentation and a vendor name, which is the market Alice sells into. The archive itself was built to moderate social platforms when the company was ActiveFence, founded in 2018 [16], repointed at generative models in 2022 starting with Cohere [17], and renamed in January [18].

What to watch

  • Whether SentinelOne acknowledges the stake in its own filings, and whether Alice keeps selling into accounts SentinelOne covers.
  • Whether any frontier lab names a third-party red-teamer in a model card instead of describing pre-release testing as internal work.
  • Whether a follow-on round or secondary sale settles the valuation nearer $1bn or nearer $700mn.
