Fiddler AI

The Fiddler AI Control Plane provides enterprises with visibility, context, and control across the agentic lifecycle with observability, guardrails, a

Trust is a fundamental part of humanity, but with the evolution of AI this decade, we are giving AI the agency to make autonomous decisions that affect people's lives and livelihoods, often without visibility into their reasoning, context for their actions, or control over their behavior. We experienced the early version of this pain firsthand with machine learning models and founded Fiddler to solve it: first with explainability, then expanded to observability to track how models change over time. As agents emerged, the same challenge resurfaced at a larger scale: autonomous systems making consequential decisions across enterprises. Organizations needed not just visibility, but control, a way to govern AI systems at scale. When governance becomes necessary, a Control Plane always emerges to enable organizations to deploy high-performing, compliant, and secure AI systems at scale. Today, Fiddler is the Control Plane for AI Agents. We believe in the promise of AI to benefit and elevate our lives in every way. We are acutely aware of the challenges when AI is deployed without proper oversight and guardrails. Fiddler was founded to bring trust, transparency, and accountability to AI everywhere. As AI systems gain autonomy and make consequential decisions at scale, responsible AI requires more than good intentions: it requires governance. Our Control Plane enables organizations to operationalize responsible AI through continuous monitoring, enforceable policies, and auditable accountability. Our approach is grounded in these principles: Our team of engineers, data scientists, product managers, and sales and marketing experts bring a wide set of skills and experiences from companies like Meta, Google, Lyft, X, Microsoft, and other well-known large companies and high growth startups. Backed by top-tier investors and trusted by Fortune 500 companies worldwide, we're recognized as one of the leading startups shaping the future of enterprise AI. Our culture is built on the values of humility, respect, kindness, transparency, and collaboration. Fiddlers are driven by the mission of the company and work hard to make a difference towards the cause.
