Do you recognize this in your sales calls?

You don't ask sharp enough questions

You know you should dig into budget and decision-making. But in the moment it feels intrusive. So you let it go. And the deal goes with it.

You lose control after the first few minutes

The conversation starts well. But somewhere it flips into a Q&A where the prospect asks and you answer. By the end, you've lost control of it.

The proposal goes out and then it goes quiet

"Send me a proposal." You send it. Then you wait. Then you wait some more. The deal that was right there is now gone.

Sound familiar? Let's talk

1

We have an open conversation

You tell me what you're struggling with in your sales. I ask sharp questions and honestly tell you if coaching is the right step. No pitch, no strings attached.

2

I review your conversations

I listen back to your recent sales calls. I spot the patterns: where you lose control, which questions you skip, at what moment the deal slips. You get an honest diagnosis.

3

Ongoing 1-on-1 coaching

We work on your live deals together. Reviewing calls, sparring on your approach, practicing the moments that decide outcomes. Until you close with confidence on your own.

Jeffrey is driven and enthusiastic. During the sessions I felt completely at ease, he works in an open and pleasant way. He gives sales a fresh angle and that genuinely moved me forward. Recommended.

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

About Jeffrey

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

I help founders sharpen the commercial side of their business. Better closing, tighter marketing and standing out in a market where everyone sounds the same.

I've cold called myself, built funnels that still generate leads years later and rewritten dozens of propositions until they actually converted. I know what works because I've done it myself.

"I don't have time for coaching"
The coaching runs on conversations you are already having and deals that are already on your desk. Not extra work, just doing the work you already do more sharply. Most sessions are 60 minutes and pay for themselves in the first week.
"I already know what I am doing wrong."
Knowing and doing are two different things. I help you bridge that gap. By practising on real deals instead of theory, and by telling you honestly what I hear when I listen back to your calls.
"How do I know whether coaching is right for me?"
We talk first. I ask questions, I listen, and I tell you honestly whether I think I can help. No strings attached, no sales pitch. If it's not a fit, I say so.
