About

I have spent my career solving marketing problems at scale.

I am a marketing strategist and consultant. My work sits at the intersection of customer behaviour, product, growth, brand and commercial outcomes.

The career arc

11+

years across marketing, growth and product.

My experience spans Amazon Pay, Amazon MX Player, marketplace brand management and earlier B2B technology demand-generation roles. The common thread is not a channel. It is diagnosing what is stopping a customer or business from moving to the next stage.

How I think

Diagnosis before channel.

I do not start with SEO, paid media, CRM or content because someone asked for a channel. I start with the commercial constraint, customer behaviour and evidence. The intervention comes after the diagnosis.

1. Find the constraint
2. Understand the customer decision
3. Choose the smallest useful intervention
4. Measure the business outcome

What I work on

The capabilities are broad. The method is consistent.

Strategy, growth, product marketing, lifecycle and brand problems often overlap. I work across the system when the problem requires it.

The intellectual work

I wrote the book I wanted to read about building brands when AI makes execution cheap.

The Sovereign Brand is an argument for building brands around a distinctive point of view, customer understanding and a system that remains valuable as technology changes.

Proof, not positioning

Read the work behind the claims.

The proof-of-work library separates first-hand experience from illustrative strategy so you can see both what I have done and how I approach problems I have not personally been hired to solve.
