Fabraix ne yapar

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.

Describe what your company does in 50 characters or less.

AI agents that red-team other AI for security flaws.

What is your company going to make? Please describe your product and what it does or will do.

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.

Where do you live now, and where would the company be based after YC?

San Francisco, CA, USA. We'll stay based here after YC.

Explain your decision regarding location.

San Francisco is where AI security buyers, technical partners, and talent are concentrated. Being here lets us move fast on product and sales.

Sıkça Sorulan Sorular

Bu, Fabraix şirketinin gerçek YC başvurusu mu?

Hayır. Y Combinator gönderilen başvuruları gizli tutar. Bu bir yeniden yapılandırmadır: gerçek YC form soruları, Fabraix'in kamuya açık verilerinden (lansman notları, kurucu geçmişleri, ürün açıklaması) yanıtlanmıştır. Fabraix gibi bir şirketin YC'ye kendisini nasıl sunacağını gösterir, gönderdikleri metni değil.
