In this episode of GTM by the Numbers, host Brandon Redlinger sits down with Bill Macaitis—the former CMO who propelled Salesforce, Zendesk, and Slack to breakout growth and now advises the next generation of SaaS disruptors through SaaS CMO Pro. Together they unpack what it really takes to build a capital-efficient, customer-obsessed GTM engine in 2025.

Bill explains why traditional last-touch attribution is broken, how to prove marketing impact with control-group experiments, and the mindset shifts every GTM leader needs in an AI-driven world. They also dive into aligning incentives across marketing, sales, and product, the underrated power of NPS, and why brand is the ultimate growth lever when budgets tighten. If you’re a GTM executive aiming to scale fast without burning cash, this conversation is a must-listen.
