White Circle, an enterprise AI governance startup focused on monitoring and securing AI systems in production, has raised $11 million in seed funding from a group of investors and operators across the AI industry.
Backers include figures associated with OpenAI, Anthropic, Mistral AI, Hugging Face, Datadog, DeepMind, and Sentry. Founded in 2025, the company develops infrastructure designed to help organisations test, monitor, and govern AI applications in real time as adoption accelerates across regulated and high-risk industries.
What The Company Does
White Circle develops a runtime governance and monitoring platform for AI systems deployed in production environments. Its platform is designed to help organisations identify safety, reliability, and compliance risks associated with large language models and AI-powered applications.
The company provides a unified API that allows teams to test, secure, observe, and optimise AI interactions. Its monitoring systems analyse prompts, outputs, and user behaviour in real time to detect issues such as hallucinations, harmful responses, prompt injection attacks, model drift, and malicious usage patterns.
The platform also enables organisations to define custom governance policies and automate enforcement actions, including rate limiting, blocking unsafe interactions, or restricting abusive users. According to the company, the system improves over time through labelled feedback and continuous monitoring data.
In addition to risk detection, White Circle offers analytics and optimisation tools designed to help enterprises evaluate AI performance and improve model reliability across live deployments.

Market Context / Industry Background
The rapid adoption of generative AI across enterprise environments has created increasing demand for governance and oversight infrastructure. As organisations integrate AI systems into customer support, finance, healthcare, recruitment, and operational workflows, concerns around reliability, safety, and regulatory compliance have intensified.
At the same time, AI development has become significantly more accessible through low-code tools, APIs, and so-called “vibe coding” workflows, allowing companies to deploy AI-powered products quickly with limited internal governance structures.
This shift has exposed operational risks related to hallucinations, data leakage, prompt manipulation, and inconsistent model behaviour in production systems. As a result, a growing market is emerging around AI observability, alignment, and runtime monitoring infrastructure.
White Circle positions itself within this category by focusing on continuous oversight rather than static pre-deployment testing alone.
Founder / Investor Commentary
Founder and CEO Denis Shilov said the pace of AI adoption is moving faster than existing governance and oversight frameworks. According to Shilov, organisations are increasingly deploying AI systems in areas that directly affect people, while the barriers to building and launching these systems continue to decrease.
He described White Circle’s objective as providing organisations with visibility into how their AI systems behave in production environments and enabling them to respond quickly when issues emerge.
Head of Design Elena Iumagulova added that the platform was designed to make AI governance accessible to both technical and non-technical teams through a unified interface covering monitoring, optimisation, and risk detection.
The investor roster also reflects growing strategic interest in AI infrastructure companies building tooling around safety, observability, and deployment governance.
Growth Plans / Use Of Funds
The $11 million seed investment will be used to accelerate product development and expand White Circle’s teams across the US, UK, and Europe.
The company also plans to grow its global customer base as demand for AI governance infrastructure increases among enterprises deploying large-scale AI systems.
Future development will focus on expanding monitoring capabilities, improving automated enforcement systems, and strengthening tools for compliance, observability, and AI system optimisation.
