  Founded in 2018, Fiddler AI has built an all-in-one observability and security platform that serves as a control plane for compound AI systems, giving enterprises standardized telemetry, evaluation, continuous monitoring, policy enforcement, and auditable governance. The product includes proprietary Trust Models that provide out-of-the-box accuracy, safety, and compliance checks, enabling Fortune 500 customers to diagnose, explain, and manage AI agent behavior in real time. Over the last 18 months the company’s revenue has grown more than 4×, reflecting rapid adoption in regulated sectors such as healthcare, financial services, and insurance. Recent milestones include achieving AWS Pattern Partner status and being ranked the #1 company in AI Agent Security & Risk Management by CB Insights. With its new control-plane capabilities, Fiddler plans to deepen integrations across the AI ecosystem and expand its footprint in mission-critical, agent-driven workflows. The latest financing brings total capital raised to $100 million, supporting continued product development and go-to-market expansion.
