From Signals to Pipeline: ABM as a Revenue System
Most ABM fails because it stops at marketing. High-performing teams run ABM as a signal-driven revenue system that aligns marketing, sales, and CS around buying groups, real-time intent, and shared pipeline goals. This session shows how to identify buying groups, prioritize accounts using live signals, and orchestrate cross-functional outreach. Walk away with a practical blueprint to turn ABM into a repeatable pipeline engine that improves win rates, velocity, and expansion.

Build an AI-Driven GTM Engine (Step-by-Step)
Most teams use AI for tasks. High-performing teams redesign GTM around it. In this Deep Dive, we’ll walk through how to build an AI-driven GTM engine that powers pipeline generation end-to-end. Learn how to structure workflows for targeting, prioritization, activation, and sales execution using real signals and automation. You’ll map your own system live, defining workflows, decision points, and handoff, and leave with a practical blueprint to improve pipeline, speed to lead, and conversion.

How To Use ABM To Generate Contact-Level Intent
Most ABM programs stop at account targeting—but pipeline is built by people. In this session, you’ll learn how to take a contact-first approach to ABM that helps you identify and generate intent at the individual level. We’ll cover how to build campaigns that surface real buying signals, connect those signals to pipeline outcomes, and empower your sales team to take action faster. If you’re tired of chasing anonymous intent data, this session will show you how to create your own—through smart targeting, real engagement, and better GTM alignment—and turn that intent into revenue.
