Adaptive Security develops a platform that uses generative AI to mimic deepfake voice, video, text, and email attacks, letting companies pinpoint where existing controls fail and deliver individualized security-awareness training. Its product suite also includes automated threat triage and AI-driven executive risk scoring to highlight an organization’s most exposed employees and processes. Publicly launched in January 2025 and headquartered in New York, the company was founded by Brian Long and Andrew Jones, who previously built Attentive to $500 million in annual revenue. In under a year, Adaptive has amassed more than 500 enterprise customers—including PayPal, Xerox, Bose, the NHL, PGA, Figma, Ramp, Vimeo, TaylorMade Golf, and Perplexity—and boasts a Net Promoter Score of 94. The surge in AI-enabled social-engineering incidents (deepfakes grew 17× from 2023 to 2024) underpins demand for its solution. Investors view the startup as a leading defense against AI impersonation, helping it raise $146.5 million across three rounds in 2025 to scale its technology and customer base.
