OpenAI Fund Deepens Investment in Adaptive Security

Adaptive Security has secured an additional investment from the OpenAI Startup Fund, bringing its Series A total to $55 million. The company focuses on preventing AI-driven social engineering attacks, and it remains the only cybersecurity company backed by the fund. The investment signals continued confidence in Adaptive’s approach to protecting people from increasingly sophisticated deception tactics.

AI-enabled threats are moving quickly from hypothetical to real. Recent cases range from fake messages sent to government officials to scams involving cloned voices and deepfake videos targeting both companies and individuals. With billions of dollars at risk, organizations are recognizing that traditional safeguards aren’t keeping pace with these evolving tactics.

Adaptive’s platform is designed to help organizations test, train, and respond to AI-powered impersonation attempts. The company uses simulated phishing and deepfake attacks, customized training programs, real-time incident reporting, and AI-driven risk scoring to strengthen defenses. The goal is to prepare employees and institutions for the kind of attacks that increasingly exploit human trust as much as technology.

For the OpenAI Startup Fund, doubling down on Adaptive is as much about timing as technology. With regulators, enterprises, and consumers all grappling with the fallout of deepfake fraud, the market for human-centered security has become both urgent and expansive. The new funding positions Adaptive to accelerate product development and expand its reach, making it a bellwether for how venture capital is shaping the defense against AI-enabled fraud.
