Full Job Description
About Adaptive Security
Adaptive is a cybersecurity startup on a mission to stop AI-powered cyberattacks. In December 2025, the company announced an $81M Series B led by NVIDIA and Bain Capital Ventures, with participation from Capital One Ventures, Citi Ventures, and continued support from Andreessen Horowitz (a16z), the OpenAI Startup Fund, and Abstract Ventures. The round marked NVIDIA’s first AI cybersecurity investment.
Adaptive was founded by Brian Long and Andrew Jones, repeat entrepreneurs who have built and scaled category-defining companies. Brian and Andrew previously co-founded Attentive, which grew to more than $500M in annual revenue and a $10B+ valuation, and TapCommerce, which was acquired by Twitter. Together, they bring deep experience building high-growth, product-led businesses at massive scale as Adaptive builds the security layer for the AI era.
Trusted by leading banks, technology companies, and healthcare organizations, Adaptive protects teams from emerging threats like deepfakes, smishing, and AI-powered voice scams. With rapid enterprise adoption and a $200B+ market ahead, the company is just getting started.
The Role

This is a high-impact, post-sales revenue role focused on increasing product adoption, identifying upsell and cross-sell opportunities, and leading strategic growth conversations with executive and technical stakeholders.
You will guide customers through the post-onboarding lifecycle, ensuring they realize value from Adaptive’s platform — and translating that value into long-term revenue growth.
This is a founding role on the Growth team. You’ll help define how Adaptive scales its expansion motion, leveraging one-to-many engagement strategies, strong operational rigor, and tactical selling execution.
