Episode Overview:

In this episode of Marketing in the Age of AI, host Emanuel Rose sits down with agency growth advisor and author Corey Quinn to unpack why niching down beats being a generalist—and how vertical specialization unlocks margin, authority, and scale. Corey also shares his behind-the-scenes playbook for a successful book launch, from community-driven momentum to endorsement strategies.

What You’ll Learn:

• Why “the generalist trap” creates bottlenecks and commodity pricing—and how to escape it

• How to pick a profitable niche using business data, personal alignment, and total addressable market (TAM) math

• The Deep Specialization Flywheel: focus → expertise → systems → leverage → premium positioning → reinvestment

• Practical steps to operationalize a niche (SOPs, onboarding “assembly lines,” and repeatable outcomes)

• Book marketing tactics that work: launch squads, public writing, and strategic endorsements
