White Circle raises $11M to help companies secure and monitor AI model behavior

What happened

White Circle, an AI guardrail and monitoring startup operating under Pumpkin Intelligence Inc., secured $11 million in seed funding. The round attracted top AI leaders, including Romain Huet from OpenAI Group PBC. White Circle’s founding claim is that most AI models can be broken with a single prompt, highlighting urgent security and reliability risks in AI deployment.

Why it matters

AI models are widely used, but their behavior can be unpredictable or vulnerable to exploitation. White Circle aims to tighten control by providing tools that secure model behavior and monitor output. This addresses a practical pain point for companies relying on AI: managing risk from manipulation or failure that could cause compliance, reputational, or operational damage. The funding signals growing investor concern about AI reliability and the need for safeguards as adoption spreads.

What to watch next

Expect White Circle to focus on developing robust guardrails that can be integrated into existing AI systems. Watch for expanded partnerships with model operators and enterprises that want to enforce usage policies or detect harmful outputs in real time. The startup’s progress will be a useful test of how much oversight can practically prevent unintended or malicious AI behavior without sacrificing functionality.
