HiddenLayer Secures $100M in Series B Funding to Expand AI Security Offerings
AI security startup HiddenLayer has raised $100 million in a Series B funding round led by Delta-v Capital, with participation from Ten Eleven Ventures, Morgan Stanley, Microsoft's M12, and Booz Allen Hamilton. The company is capitalizing on the growing demand for AI security tools as enterprises increasingly deploy artificial intelligence systems. HiddenLayer’s annual recurring revenue has grown more than 10 times in the past year, reaching tens of millions of dollars, driven largely by new customer acquisitions. Its clients include major financial institutions, large tech firms developing AI products, and government agencies such as the Department of Defense and intelligence community. The company is also working with a prominent frontier model provider that serves over 700 million weekly users. The funding will be used to expand sales and distribution efforts while continuing engineering and research development. HiddenLayer plans to extend its security solutions—such as runtime protection, attack simulation, and supply chain security—to address emerging threats like prompt injection and agent manipulation.
