Customer Success Manager

About

Adaptive is a cybersecurity startup on a mission to stop AI-powered cyberattacks, founded by Brian Long and Andrew Jones—proven entrepreneurs behind Attentive (Forbes Cloud 100, $10B+ valuation) and TapCommerce (acquired by Twitter). In April 2025, Adaptive raised $43M, led by a16z and the OpenAI Fund, marking OpenAI's first-ever cybersecurity investment.

As generative AI drives new cyber threats, Adaptive is building the defense layer every organization needs. Our platform combines personalized security training, AI-driven attack simulations, and automated threat triage, all powered by the Adaptive Risk Intelligence Engine to quantify human risk at the individual level. Trusted by top banks, tech companies, and healthcare organizations, we protect teams from emerging threats like deepfakes, smishing, and voice scams. With a solid product foundation and a $200B+ market to transform, we're just getting started.
