À propos

About Cascade AI Cascade AI helps HR organizations transform how they operate with AI agents that automate critical HR functions, including support, open enrollment, onboarding, leave of absence, compensation, and more.
Our agents do far more than provide answers. They execute processes and workflows, streamline HR operations, and deliver employees the help they need instantly and conversationally. A combining large language models (LLMs) with an organization’s existing HR technology stack, Cascade agents streamline operations, improve employee experience, and unlock significant cost savings.
Cascade is deployed globally, with users on every continent, and supports multi‑lingual workforces. We are proudly backed by Gradient Ventures, Google's AI fund, and trusted by Fortune 100 companies and leading enterprises, many of whom sign multi‑year contracts. Founded by two former Microsoft engineers through the MIT Sandbox Innovation program, Cascade is now one of the fastest‑growing AI companies in HR technology.
We have an exceptional advising team, including industry leaders such as the former VP of People Ops at Google and former CHRO of Airbnb.
