Company Overview
Adaptive Security is a New York-based cybersecurity startup focused on protecting organizations from AI-powered threats such as deepfakes, phishing, voice scams, and risky AI usage. Its platform combines security awareness training, AI governance, phishing simulations, and agentic email security.
Founded in 2024, Adaptive has raised $100M+, including an $81M Series B announced in December 2025. Investors include NVIDIA, Bain Capital Ventures, Capital One Ventures, Citi Ventures, OpenAI Startup Fund, Andreessen Horowitz (a16z), and Abstract Ventures.
The company currently lists 201–500 employees on LinkedIn and says more than 1,000 organizations use its platform.
Adaptive’s core idea is simple: as AI makes cyberattacks more convincing and scalable, organizations need security that protects the human layer across email, voice, messaging, browsers, and AI tools—not just traditional network infrastructure.

The most important unknowns are its revenue, profitability, valuation, and exact employee count, which aren't publicly disclosed with enough certainty to state as facts.
