White Circle sells a control layer a company runs between its own application and the AI models it uses, so the company decides what those models may do. Individuals who built at OpenAI, Anthropic, and DeepMind backed the 11 million dollar seed, funding a layer that constrains the class of models their companies build. The founder earned that audience by jailbreaking major AI models with a single prompt, and early customers include the app builder Lovable and two large digital banks. White Circle is betting that safety cannot be settled inside the models, so its natural buyer is the regulated enterprise that wants to own its AI controls rather than rely on a model provider.
