Marketing systems: CRM, data & AI

Systems, activated.

Content, ads, website, CRM and analytics work as one system. I connect them, measure what moves between them, and keep it in motion.

01

What I do

CRM & automation

I made the case for a CRM for years. When HubSpot finally came in, the data side was mine: the migration, and keeping it clean enough that colleagues can run it without me.

HubSpot · Forms · Workflows

Case: the CRM story

Analytics & reporting

Ads, website and course bookings in one picture, behind budget decisions, tooling choices and a stronger hand in negotiations.

GA4 · Google Ads · Meta · Eventbrite

Case: one dashboard

Search & content

Paid campaigns run in-house, articles written to rank, and what people search for fed back to the team developing courses.

Google Ads · SEO · Content

Case: from search to course

AI adoption & governance

Choosing the tools, running the pilot, writing the rules, and training colleagues to use them.

How I work

Follow what moves

In ecology I studied what moves between systems. In marketing it’s the same question: what happens between the page, the form, the CRM and the inbox?

Design the rules

Automation and AI are only as good as the rules behind them. I write those rules down, so colleagues can follow and change them.

Know what you don’t

Saying “I don’t know” beats a confident guess. Good data work shows where it stops.

04Research

Counting, listening, and other ways of knowing

Four studies, four angles: tracing nitrogen in Peru, listening to how people experience nature, comparing city green across Europe, and going back six years later.
