How I work

A holistic view of marketing and sales.

Commercial growth only works when the parts fit together. So I always look at the whole first.

Positioning
Who are you for, and why you?

It is not about what you do. It is about how your customer sees you. I help you find that position and put it in words sharp enough that the right people recognise themselves straight away. That shapes everything: your website, your conversations, your pricing, the direction you grow in.

Proposition
What do you sell, and what does it deliver?

Most founders offer too much and describe it too vaguely. Together we look at what you sell, how you package it and whether it matches what your customer actually needs. Usually that means cutting: fewer services, tighter focus, plainer language.

Marketing funnel
How do customers find their way in?

A funnel is a deliberate route from visibility to customer. Content that attracts, a website that converts, a call to action that gets people moving. So you are not hoping the phone rings every month, but running something that produces leads predictably.

Sales approach
How do leads become customers?

If the conversation is off, that is where your revenue leaks away. I look at how you run your conversations, coach you on the moments that decide the deal and train your team on real calls. The difference between a 30% and a 60% close rate usually sits in small things.

All the ingredients for a good recipe were already on the table, but the recipe itself was missing. In a one on one session Jeffrey walked me through writing it out, which is to say our sales strategy. A strategy that lets us aim with far more purpose.

Jeffrey is a no nonsense coach. He knows his field and is not afraid to tell you plainly where things go wrong for you. The best part is that he then takes you by the hand and shows you how to fix it. Recommended.

What I value most about working with him is how easy it is to have open conversations. Jeffrey has a pleasant way of working: he puts you at ease and lets you be completely yourself, while still bringing a sharp and honest point of view.

Jeffrey helped us enormously with our offer and our marketing strategy. When we first came to him we had only just started. Six months later we are almost fully booked for the whole year.

After my first one on one session with Jeffrey I could tell he knew a lot about both the person and the sales.

Jeffrey has a natural calm about him, which makes him easy to talk to. In our intake he got to the core of what I needed quickly, and shortly after that call I had a clear plan for how we would work on it together.

About Jeffrey

Doing what actually works instead of frameworks out of a book.

I started out in the music industry, booking artists. Cold calls, winning people over, building relationships, and hearing no far more often than yes. Then I started doing it for other people: rewriting offers until they actually converted, building funnels that still bring in leads years later, coaching sales teams on their own recorded calls.

Fifty companies later. Solo operators and agencies, and the occasional partnership with a Heineken or an Adidas. What keeps me in this is the moment it clicks and the whole system starts running the way it should, pulling in the kind of clients a business is glad to have.
