How I help

From idea to offer, direction for your marketing – and extra hands for your team.

For founders and leaders

Turn your idea into a concept customers can buy.

You have an idea, a new service or years of expertise that’s hard to explain. I help you clarify it into a ready concept, put it into words and commercialise it. I also write your thinking in your own voice – articles, posts and speeches.

For marketing teams and agencies

Flexible extra support for your marketing team.

From website development to content production and social media – I join your team when you need more hands and step back when you don’t. I also work as a subcontractor for advertising and communications agencies and software development companies.

For companies without a CMO

A marketing lead – without a full-time hire.

I set the direction, build the plan and lead the work part-time. Billed by the hour – as much or as little as you need.

How it works

From chaos in your head to things you can actually sell.

In your head right now

I have a great idea – but who pays for it?

We’ve done this for 10 years. How do I explain it?

It’s all in my head.

Every offer is custom. Every time.

What do we even charge for this?

Customers ask: “So what do you actually do?”

Every sale starts from scratch.

How do I turn this into a product?
