Sound familiar?

Do you recognise this in your sales calls?

You go into the conversation feeling unsure

You've prepared, but as soon as the call starts you doubt your own story. The prospect hears that doubt too. And doubt doesn't convince anyone.

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.

You find it hard to gauge interest

The conversation feels good, but you don't know where you stand. Is the prospect genuinely interested or just being polite? You only find out when it's too late.

You barely handle objections

"Too expensive." "I need to think about it." You nod, offer a discount or let it slide. Even though an objection is exactly the moment to follow through.

Your proposals fall through (too) often

"Send me a proposal." You send it, you follow up, and then it turns out it's not happening after all. Or you never hear back at all.

Recognise this? Let's meet

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 and look for the patterns: where you lose control, which questions you skip, at what moment the prospect drops off. You get an honest diagnosis.

Ongoing 1-on-1 coaching

We work with your live deals. You get targeted feedback on your real conversations and we practise the techniques on the moments that matter. So you always know exactly what to do better next time.

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

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.

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.

About Jeffrey

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

I help founders, account managers and salespeople get stronger in their conversations. Sharper questions, more control and more deals signed, 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.

FAQ

Still in doubt?

Is your question not here? Just ask me.

"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 90 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.
"I don't run my own business. Is this for me too?"
Yes. Whether you run the company, manage accounts or sit in a sales team: the moments where a deal is won or lost are the same. I coach on your conversations and your deals, in your context.
"What if it is my team that needs to sell better?"
Then we work with the team instead of just with you. Same approach, different format: I listen back to their calls and train them on their own deals. That variant lives at sales training.
"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.
