How to Build a Real GTM System for Your Agency with Garrett Jestice

In this episode, Dan Englander sits down with Garrett Jestice, former CMO and founder of Prelude, to unpack how to turn that randomness into a repeatable Go-To-Market (GTM) system that actually compounds.

Garrett helps B2B agencies and service businesses replace scattered marketing efforts with a focused GTM strategy built on customer proof — clarifying audience, offer, messaging, and channels so growth stops being a guessing game.

They break down why most agencies start with the wrong things (channels before clarity), how to pick the right market segment, and how to make growth repeatable without losing focus or burning resources.
