Cosa fa Fabraix
Fabraix builds state-of-the-art AI red-teaming agents that continuously detect security vulnerabilities in customer-facing AI. Our product, Nyx, has already found vulnerabilities in agents at dozens of Fortune 500 companies. On AgentHarm, the leading benchmark for offensive AI security, Nyx achieved a 78% attack success rate, compared with 67% for GPT-5.6 Sol. AI agents can change more often than teams can test them. A new model, prompt, tool, permission, or data source can change what an agent does, even when the application code stays the same. And AI is also increasing how much software companies produce and how often it changes. We built Nyx to automate the work required to red-team AI agents. It is multi modal by design and interacts with the target indirectly through controlled replicas of SaaS products and websites that we maintain, placing malicious payloads in webpages, documents, files, messages, and tool outputs to test how an agent behaves under different conditions. Nyx often finds its first vulnerability within minutes or hours rather than days or weeks. Because the work is fully automated, companies can repeat the test with every change and at a much lower cost than what a 7-figure red-teaming (and point-in-time) engagement would require. We're also the team behind ACE (Adversarial Cost to Exploit), a benchmark that measures AI security in terms of how much it costs attackers to break an AI system; providing a game-theoretic framework to understand how motivated a rational attacker would be in exploiting the system.

Company
Fabraix
AI agents that red-team other AI for security flaws.
We're building Nyx, an AI agent that acts as an autonomous red-teamer to find vulnerabilities in customer-facing AI systems. It targets changes in models, prompts, tools, and data sources - areas that traditional security reviews can't keep up with. Nyx runs multimodal attacks by interacting through replicas of real SaaS products and web systems, planting payloads to test agent boundaries. The goal is to give companies a way to catch issues as fast as they ship changes, at a fraction of the cost of human red-teaming.
San Francisco, CA, USA. We'll stay based here after YC.
