Austin-based HiddenLayer, a provider of AI security tools, secured $100 million in Series B funding led by Delta‑v Capital.
Austin‑based HiddenLayer, a specialist in AI‑runtime security, announced a $100 million Series B financing led by Delta‑v Capital, with participation from Ten Eleven Ventures, Morgan Stanley and M12. The round follows a $50 million Series A three years ago and is aimed at scaling the company’s platform that protects AI models, agents and workflows from adversarial attacks, vulnerabilities and malicious code injections.
The funding comes as enterprises accelerate AI deployments and confront a growing threat landscape. HiddenLayer’s tools monitor AI systems in production, detecting anomalies, model manipulation and injection attempts in real time. By offering an end‑to‑end security stack, the startup positions itself to meet demand for safe, compliant AI adoption at scale—a need that has intensified as generative models and autonomous agents move beyond pilot projects into core business processes.
The investment underscores the market’s appetite for dedicated AI security solutions and signals confidence in HiddenLayer’s technology. For investors, the participation of both venture firms and institutional players such as Morgan Stanley highlights a broader shift toward infrastructure‑level AI safeguards.
Going forward, HiddenLayer is expected to expand its product suite, deepen integrations with cloud providers and AI platforms, and pursue partnerships that embed its protection layer into enterprise AI pipelines. Observers will watch how the company leverages the new capital to address emerging attack vectors, especially as regulatory scrutiny of AI safety tightens across Europe and North America. The next milestones will likely include customer wins in high‑risk sectors, further fundraising rounds and potential acquisitions that could consolidate the nascent AI security market.
