AI governance, monitoring, and testing platform

Overview

Citadel AI provides a platform for governing, monitoring, and evaluating AI systems across industries such as finance, healthcare, automotive, and manufacturing.

The platform automates stress testing, generates actionable reports, and continuously tracks model performance from development to production, all under tiered subscription plans for businesses. Its differentiators include a leadership team with experience in enterprise management and AI engineering, a focused combination of safety, security, and compliance tools, and a global B2B approach that integrates testing, monitoring, and lifecycle governance in one system. Citadel AI aims to make AI systems safer, more reliable, and easier to manage over time, helping organizations reduce risk while speeding up AI development and deployment.
