| Dec 2025 | Series B | Bain Capital Ventures (lead); OpenAI Startup Fund; NVentures; Andreessen Horowitz; Capital One Ventures; Citi Ventures; Abstract | $81M | Adaptive Security is a New York-based cybersecurity startup founded in 2024 that provides an AI-powered platform to defend against social engineering attacks, including deepfakes, impersonation, and multi-channel threats exploiting human trust rather than technical vulnerabilities. The platform simulates AI-driven deepfake phishing, offers executive risk scoring, automated threat triage, and tailored training programs to identify vulnerabilities and mitigate risks for enterprises. On December 16, 2025, Adaptive Security raised an $81 million Series B funding round led by Bain Capital Ventures, with participation from NVentures (NVIDIA's venture arm), OpenAI Startup Fund, Andreessen Horowitz (a16z), Abstract Ventures, Capital One Ventures, and Citi Ventures. This marked the company's third fundraising announcement in 2025, following a $43 million Series A in April led by OpenAI Startup Fund and a16z—OpenAI's first cybersecurity investment—and a $12 million follow-on in September led by OpenAI Startup Fund, bringing total capital raised to $146.5 million. The funds will expand platform capabilities, accelerate product development focused on human-layer security, grow the team, and advance efforts to secure AI systems. Since its public launch in January 2025, Adaptive has rapidly grown to over 500 enterprise customers, including PayPal, Xerox, Bose, NHL, PGA, Figma, Ramp, Vimeo, TaylorMade Golf, and Perplexity, while reporting a Net Promoter Score of 94. Customers have reported increased deepfake incidents, with over half of conversations noting such activity in 2025. Co-founders Brian Long (CEO) and Andrew Jones bring experience from prior ventures TapCommerce (sold to Twitter in 2014) and Attentive, both backed by Bain Capital Ventures. Investors highlight the founders' track record and the rising board-level priority of AI-enabled threats, where social engineering drives over 95% of breaches per industry reports. |
