About Adaptive Security
Adaptive Security is an innovative cybersecurity startup dedicated to combating AI-driven cyber threats. Following a successful $81 million Series B funding round in December 2025, led by NVIDIA and Bain Capital Ventures, the company is backed by notable investors including Capital One Ventures, Citi Ventures, and Andreessen Horowitz (a16z). This funding round marked a significant milestone as it was NVIDIA's inaugural investment in AI cybersecurity.
Founded by seasoned entrepreneurs Brian Long and Andrew Jones, who have a proven track record of building successful companies, Adaptive aims to create a robust security framework for the AI era. Their previous venture, Attentive, achieved over $500 million in annual revenue and a valuation exceeding $10 billion, while TapCommerce was acquired by Twitter. With extensive experience in scaling high-growth businesses, Adaptive is poised for success in the evolving cybersecurity landscape.
Trusted by prominent banks, tech firms, and healthcare organizations, Adaptive Security provides protection against emerging threats such as deepfakes, smishing, and AI-enabled voice scams. With rapid adoption in the enterprise sector and a market opportunity exceeding $200 billion, we are just getting started.
