Working at Knock AI

Knock AI is reinventing how B2B companies build relationships with buyers in the AI internet.

The way people buy has changed. Intent now happens across AI, messaging, ads, events, content and social, and momentum disappears fast. But most GTM systems are still built around capturing a lead on a website and following up later.

Knock gives companies a new way to operate. They can become accessible to buyers from anywhere and use AI to build relationships across channels and languages, turning moments of interest into revenue.

In just two years, Knock has become strategic infrastructure for enterprise marketing and revenue teams, driving meaningful revenue impact and replacing multiple parts of the traditional marketing and sales stack.

But the shift is only beginning.

This is not another GTM tool. It is a new marketing and sales model, with new playbooks, new ways to engage buyers, and a fundamentally different way to think about growth.
