“Immediate results. Klaas fundamentally changed our sales team, not with tricks but with an approach that truly works and sticks.”
More revenue, less stress
with the Sales Excellence Training
Sales training for sales reps, account managers, sales teams and entrepreneurs who want to get more out of their customer contact, without tricks or pressure. Together we put together your tailored programme: online, at your premises, or at our fixed training spots (my office or the beach of Castricum aan Zee).
Your trainer is Klaas Kroezen, author of the bestseller 'Sales, Honest & Relaxed'.

You get the sales training directly from me, Klaas. Author of the bestseller 'Sales, Honest & Relaxed'.
From my own company I sold to brands like Google, Microsoft, ING and Samsung, until I sold my company in 2022. What I learned there, I now share with teams and people like you.
We apply the sales training fully to your business, for teams and individuals. No standard story, but your customers, your situation, your goals.
What it costs
to leave it as it is.
Every month you wait is revenue you won't get back. The approach changes that, step by step.
- Targets you keep missing, while the pressure on your team rises.
- Deals you lose because discounting becomes your only card.
- Good people who drop out for lack of structure and energy.
- Customers who leave for a competitor who does stand out.
No fixed format.
We decide the route together.
We offer different formats, and we start just as often with an on-location inspiration session as with the online theory. Together we look at what delivers the most for you or your team. Always tailored, never one-size-fits-all.
Get acquainted
We start with a no-obligation conversation or an inspiration session on location. That's how we discover together what you really need.
Your tailored path
We design the programme together: theory online where it helps, the real training always on location and tailored to your practice.
Apply & keep improving
You sell honestly and at ease, and with the Customer Experience Model you keep a grip on your customer experience, continuously better.
How do you get a grip
on your sales?
With the Customer Experience Model you make your customer experience measurable across six areas: Genuine, Relaxed, Beliefs, Form, Content and Process. You see where you stand and where the most to gain is, and you keep improving with it. Even after the training. That's how you get a lasting grip on your sales.

We're happy to help.
Yes. Almost everything we do is tailored. You cover the theory online at your own pace, so we spend the sessions on location entirely on your practice: real cases, your own customer conversations and your team. On location means: at your premises or at ours. A one-on-one programme I almost always do at my office, with groups we can also go to an inspiring place, for example the beach of Castricum aan Zee.
You always train directly with sales trainer Klaas Kroezen, author of the bestseller ‘Sales, Oprecht & Ontspannen’ and with over 25 years of international B2B sales experience at companies including Google, Samsung and Vodafone. No junior trainer or intermediate layer: you are guided by someone who practises the craft himself every day.
The online sales training costs 2,750 euros, the Online + Coaching variant 4,250 euros, both excluding VAT and including the bestseller Sales, Oprecht & Ontspannen. For teams and in-company programmes we create a tailored proposal. Most clients earn back the investment during the training itself, simply by negotiating better.
For anyone in a commercial role: sales professionals, account managers, business developers and sales managers. Whether you have 2 or 20 years of experience, the method adapts to your level.
The online training consists of 6 modules plus a bonus module you complete at your own pace. The training takes 5 hours, which most participants spread over 3 to 5 weeks. You get access immediately after payment and can start right away. The variant with (team) coaching adds personal guidance.
Yes. If you choose Online + Coaching, Klaas guides you personally as your sales coach: individual sessions, role-plays and a tailored action plan, aligned with your customers and goals. You apply what you learn directly in practice, and you're never on your own.
Not sure which format fits you? Book a no-obligation call first and we'll look together at what works. Either way you train directly with Klaas himself, so you know exactly who you're working with.
Yes, we also offer the sales training in-company, fully tailored to your team. With group exercises, team-focused cases and on-the-job guidance. Many teams start with a sales inspiration session: half a day on location, with inspiration and practical tools. The ideal first step before taking on the full programme with your team. Get in touch for a proposal.
No scripts. We work from genuine connection and ease. The result: more revenue that also feels right. Based on 25+ years of hands-on experience.
