Ep 123 - Why the funnel is breaking your go to market and why closed loops are the answer (Closed Circuit Selling) w/Charles Needham & George Coudounaris

Closed Circuit Selling: Why the Funnel Is Breaking Your GTM
Most go-to-market teams aren’t failing on effort. They’re failing on architecture.
In this episode, we sit down with Charles Needham (co-author of Cold Call Algo) alongside Adem Manderovic (CRO School) to break down why the linear funnel is the biggest sacred cow in sales, and why Closed Circuit Selling is the better model for modern outbound.
We unpack incentives, silos, CAC payback insanity, and why “meetings booked” became a broken religion. Then we get practical. How to run outbound as market learning. How to capture timing signals. And how to build feedback loops that actually make marketing, sales, and customer success stronger together.
Tune in and learn:
Why buyer journeys are non-linear, and funnels create blind spotsHow to shift from meetings quotas to conversation-driven market validationWhy intent data can’t replace first-party conversations
If you’re a B2B marketer or revenue leader, this is the blueprint for building a GTM system that compounds instead of churns.
