Importers who sell to businesses, not to consumers.
Clavis WijnimportThe strategy lives in your head. So everything still runs through you.
It explains what you do, but not who it's for, or why that customer should pick you.
What works stays with one person and never gets repeated.
A lead who doesn't buy today never hears from you again, because no system remembers them.
Not sure where it goes wrong for you? I'll show you in 10 minutes.

You can have the sharpest positioning there is, but if your website, your messages and your CRM don't carry it out, no customer ever notices.
I sharpen the strategy, then build it into your website, your outbound and your follow-up.
Strategy firms deliver a deck and leave. Execution agencies build tools without knowing your customer. I do both, in that order: first we decide who your customer is and what you say, then I build the systems that do it every day.
Who you make it for, why they pick you, what it costs and what you say. A decision, not a tagline.
One playbook for your team: who to approach, what to ask, how to demo and how to close. Built from your own won and lost deals.
New conversations with exactly the customers from your strategy. I run your outbound every week, with messages we test together.
Your CRM, your follow-up and your reporting in one place. Marketing and sales look at the same numbers, and every lead gets a next step.

With single deals up to €120k. I'm Wouter. I work out the strategy with founders, then build the marketing and sales that carry it out. No 200-slide decks, no theory that doesn't work in the real world.
Sell Successfully is based in Eindhoven and works with B2B founders and sales teams, from software and apps to media and high-ticket services, mainly in the Netherlands, Belgium, Germany and the UK.
Tools don't sell. Process sells. Tools just enforce the process.
If your playbook lives in heads, it's already dying.
90% of what I build goes into the CRM you already pay for.
The best work is done together. Here's how some of them experienced working with me.
I worked with Wouter on my GTM strategy. Because he knows success is not just a good website, it's also about the sales. We went through our entire GTM strategy together and he laser focused us on our target audience. He asked the right questions and challenged us in a way that just pushed us.
Wouter ran the full outreach engine. He wrote and refined the email and LinkedIn messaging, ran the campaigns, managed the outreach team, and kept improving what we sent based on what was landing. Most importantly, he turned that work into real meetings with founders and decision makers, which is what a sales team needs most. Any team building outbound would be lucky to have him.
Working with Wouter was fantastic. Where you'd normally have to supply all the content yourself, Wouter writes the right copy straight away and all you have to do is refine it. He knows what your customer wants to see and how to present the information on the website in a smart, attractive way. On top of that he works super fast, replies quickly and completely, and took a huge amount of work off my hands. In short: a 5-star experience!
I have been working 2 years with Wouter and he has been a key partner to help my business grow and succeed. In this new digital era, standing out online is essential. And he knows how to do it.
We were struggling with defining our online identity and marketing strategy. Wouter pierced through our strategy, defined an appropriate online identity and built two innovative websites that align perfectly with our demands. I would highly recommend working with him.
You guys are always 3 steps ahead. Every step we thought of, you added three steps more to it. I fall in love every time I see it.
Our brief to Wouter went beyond building a website: we wanted the code as lean as possible, with minimal HTML file sizes and smart use of SVG throughout. Wouter and his team understood exactly what we were aiming for and delivered brilliantly. They even recreated animations in SVG to meet our requirements, showing real care for the details that mattered to us.
A developer who genuinely thinks along with you. Wouter built us a clear, easy-to-use system for scheduling and managing over 100 staff at our creative campsite, which is going to save us a lot of time. He is enthusiastic, passionate, flexible and actively involved, often looking beyond the original brief.

For business owners who suspect they're missing opportunities but aren't sure where.
For companies ready to systematically build their commercial foundation, and implement it with their own team.
For founders and GTM leaders who need their commercial foundation built, tested and launched now, not later.
If my team and I don't get you the outcome that was discussed, we keep working for free until we do.
Your VPs are excellent at executing within their function. But GTM foundation (positioning, ICP, messaging) sits above sales and marketing. It's the layer that aligns both teams. Most companies don't have anyone owning this cross-functional foundation, so marketing and sales stay misaligned.
Most positioning work lives in a deck nobody uses. If your sales team can't articulate your positioning in 30 seconds, or if prospects still don't understand what you do differently, your positioning isn't working. We fix that.
Even better. I spent years selling behavioral research software to academics and Fortune 500 teams. Eye-tracking technology. Physiological sensors. If you can explain it, I can help you sell it better.
Fractional leaders are great for ongoing execution. But they cost €5-8k/month and take 3-6 months to diagnose and fix foundation issues. The Growth Strategy builds that foundation in 4 weeks. Then your fractional leader executes against a sharp strategy instead of guessing. And if you want me as a fractional leader? Awesome, let's chat.
If you're pre-product, you're too early. If you're post €200k ARR or about to launch and expand, you're at the perfect stage. This foundation prevents expensive mistakes and wasted runway.
If you don't have a product yet. If you only want a strategy deck, or only someone to install a tool. I do both, in that order.
Companies that sell to other businesses and win their deals in conversations: software and apps, media and publishing, programmes and high-ticket services. If you talk to real decision makers and a deal takes weeks or months, the fundamentals apply.
Absolutely. Start with the €500 audit. See the value. Then decide if you want the full strategy or ongoing partnership. No pressure.
You don't need a new tactic or more content. You need someone who gets your business and says: "This is your customer. This is what you say to them. And this is what we build, so it happens every day."
