HiddenLayer raises $100M for enterprise AI security

AI security startup HiddenLayer has raised $100 million in a Series B round led by Delta-v Capital, with participation from Ten Eleven Ventures, Morgan Stanley, Microsoft's M12, and Booz Allen Hamilton. The Austin-based company protects AI models, agents, and workflows from adversarial attacks, vulnerabilities, and malicious code injections. CEO Chris Sestito said annual recurring revenue grew more than 10x over the past year and now stands in the 'tens of millions' of dollars, with over 90% of growth driven by new customers. HiddenLayer has expanded its product scope from traditional machine learning to generative AI and agentic systems, addressing prompt injection, agent manipulation, and malicious tool use. Gartner estimates companies will spend $2.83 billion on AI security products in 2026 and nearly $4.78 billion in 2027. The new capital will support sales, distribution, engineering, and expansion into Europe and EMEA.
