All the ingredients were there, but we were missing the recipe. In a 1-on-1 session, Jeffrey helped me write it: our sales strategy. Now we're far more targeted.

Jeffrey is a no-nonsense coach. He knows his stuff and won't sugarcoat where things go wrong. But the best part? He takes you by the hand and shows you exactly how to fix it.

About Jeffrey

From artist booker to commercial strategist.

My commercial career started in the music industry. As an artist booker I learned what selling really means: cold calls, getting a no and keeping going. That's where I developed a feel for what wins people over. Over the years I started doing more for other founders: sharpening propositions, building funnels and coaching sales teams.

By now I've done it for over fifty businesses. From startups and agencies to complex partnerships with brands like Heineken and Adidas. What drives me is the moment it clicks. When a founder sees what was holding them back, we fix it together, and the results show up in the numbers.
