Arthur AI

Arthur provides an AI control plane and governance platform that enables teams to detect, govern, and improve AI across enterprise security, audit, governance, engineering, and product teams. The platform is model-agnostic, framework-agnostic, and cloud-agnostic, deployable as SaaS, hybrid, or on-premise, ensuring data never leaves the customer system. Arthur provides two core solutions: Agent Security and Governance for finding every agent in the environment, assigning ownership and risk, and enforcing policies at the scale of thousands of agents, with automated discovery across OpenTelemetry, MCP, network and cloud APIs, risk scoring, ownership and policy enforcement, SOC 2 compliance, RBAC, SSO, BAA, and immutable audit logs; and an Agent Development Toolkit for versioning prompts, running structured experiments, tracing every run, and catching regressions before users do, with versioned prompts and one-click rollback, A/B experiments on real production data, and full-trace observability and live evals on OpenTelemetry. Core capabilities include AI performance evaluations with automated pass/fail judgments on every interaction, agentic observability and tracing capturing the full reasoning chain across every LLM call, tool, and retrieval, and policies and guardrails with the same evals enforced synchronously pre- and post-LLM with actions attached to every judgment. Arthur addresses the reality that only 25% of AI projects return their investment, with the gap rarely being the model but rather the lack of a shared system between people who govern AI and people who build it. The platform provides 24/7 continuous oversight, 100% accountable agents with every discovered agent getting an owner, risk class, and enforced policy, and zero silent regressions with evals catching quality and safety drift before reaching users. Founded in 2018 and headquartered in New York, Arthur has raised approximately $63 million in Series B funding from investors including Work-Bench, Index Ventures, Acrew Capital, Greycroft, Plexo Capital, Homebrew, and AME Ventures. The company employs approximately 38 people.
