THE ADAPTIVE BRIEF — A NEWSLETTER FOR SAAS MARKETING LEADERS

Your marketing playbook is aging in real time. Build one that learns.

Every other week, I share one adaptive go-to-market framework, one real signal from the field, and one thing to stop doing — in five minutes or less. No fluff, no recycled best practices.

THE CORE IDEA

“Marketing should get smarter as it moves — not just after the fact.”

Static personas, rigid playbooks, and quarterly campaigns were built for a market that no longer exists. Adaptive marketing treats every program as a living system: sensing, learning, and pivoting while it runs.

The book

The Adaptive CMO

The Secret to Revenue, Relevance, and Results. A new operating system for go-to-market strategy — pattern recognition, living personas, dynamic positioning, and campaigns that learn while they run.

For CMOs, VPs of Marketing, and any leader tired of chasing a market that refuses to stand still.

★★★★★
“Instead of recycling the same old best practices, Rathwick lays out frameworks for living personas, adaptive campaigns, and a culture where testing is the norm.”
Amazon reader review
THE OPERATING MODEL

Six pillars of adaptive marketing.

01

Living Personas

Understand buyers in motion, not as profiles frozen on a wall two years ago.

02

Dynamic Positioning

A fixed spine, a flexible surface. Stay relevant without burning a quarter on a rebrand.

03

Adaptive Programs

Campaigns designed to learn while they run, so the insight arrives in time to use it.

04

Smarter Metrics

Numbers that teach you what to do next, not dashboards that decorate what already happened.

05

A Culture of Adaptation

A team that treats a failed test as data, and the shortest distance between wrong and right.

06

Flexible Stacks

A martech environment that accelerates learning instead of locking you into last year’s setup.
