„You already learn a lot about sales in financial services, but in the Sell Smart Academy with Heiko I closed so many more deals and generated so much more commission – I wouldn't have thought it possible!“
Hypnotherapist & Emotion Coach · MindTraveller
Hypnosis & Coaching80% closing rate
„In the coaching with Heiko we worked through concrete situations from my initial calls. He showed me how to structure my conversations, communicate my work clearly and explain more precisely what my support can mean for each individual person. Today my conversations are much calmer and clearer. Even when questions, doubts or objections come up, I can respond calmly and confidently and connect better with the person in front of me. My closing rate now sits at around 80 per cent.“
Managing Director · SoundSquirrel UG
Audiobook Production5x annual revenue
„Thanks to Heiko, I'm now seen as a serious partner by the publishers who used to just brush me off. That has already led to several successful projects. Before Heiko's Sell Smart Academy I could only dream of this. Now it's reality.“

Financial Services for CyclistsProfit doubled
„Thanks to Heiko, I won more than 100 new clients in six months and my closing rate rose from 45% to over 80%. As a result I was able to grow my monthly profit from €4,000 to €8,000. Heiko's Sell Smart Academy is the best coaching I have ever booked.“

Copacking & POS Displays+370,000€ annual revenue
„After working with Heiko, we won major brands like Gönrgy as clients. We tried many trainers, but the only one who could truly deliver provable results was Heiko. Both in 1-on-1 and in his Sell Smart Academy, he helped us achieve enormous revenue growth.“

„By working with Heiko, I first multiplied my annual revenue fivefold and then doubled it again – so a tenfold increase in just 2 years! That's mainly because Heiko gets straight to the point with every tip and every sales strategy. So you have my hundred-per-cent recommendation for the Sell Smart Academy.“

Online Shop Development+42% revenue

Managing Director · Zweidick Werkzeugbau GmbH
Toolmaking+80 new clients
„Before working with Heiko, I lost my biggest client (80% of total revenue). I was worried I'd have to let some of my staff go. After just a few months in Heiko's Sell Smart Academy, I had so many orders that I even took on an additional employee.“

I'd already been to 3 trainers before Heiko. None of them taught me new techniques the way he does. On top of that, the personal support. You won't find anything like it anywhere else! Whatever it is: Heiko helps! Quickly and with real substance. If you want to move your sales forward, you're in the right place.
My investment in the mentoring with Heiko paid for itself within 4 months. Closing rate up massively, more appointments, more referrals. He's almost always reachable – even at the weekend – and offers content you genuinely can't get anywhere else.
Heiko's approach is really interesting, especially for the Swiss market. It works extremely well. My numbers have gone up significantly and I'm super happy. If you're self-employed or an entrepreneur, I can only warmly recommend Heiko's Academy to you.
I've been to many trainers. NONE of them is like Heiko. I increased my commission by around 60% in the first six months of the Academy. For everyone looking for a sales trainer: here you've found an absolute diamond.
Even for me, as an experienced telesales professional, Heiko's approaches are refreshing, new and different. He has mastered paraverbal communication like no other trainer. My conversations are easier, more relaxed and considerably more successful than before.
I'm a psychologist and with Heiko I learned to market myself better. I've now been in coaching for 7 months: every interaction is a pleasure, the response speed is phenomenal, and the content is – even from a psychological point of view – outstanding.
The best thing that happened to me in 2022! I was able to increase our revenue by 30%. If the Lambo trainers get on your nerves as much as they did mine – here's a trainer whose focus is genuinely on sales and not on status symbols.
Thanks to his clear, practical strategies, I now lead my conversations more easily, more authentically and more successfully. Especially in handling objections, he's shown me new, effective ways. I've already been able to close several conversations far more easily.
You ask Heiko for a fish and he doesn't just set a whole basket of fish at your feet – he teaches you how to fish at the same time. I took 9 pages of notes. After putting it into practice, we increased our sales by around 20%.
The sales training with Heiko Raatz is simply fantastic. The live sessions are very personal, open and practical. You feel seen, taken seriously and motivated. An absolute recommendation for anyone who wants to sell authentically and with joy!
We're now even starting our 2nd year with Heiko. Simply because with Heiko it's not about quick money, but because he takes the time until you've really understood everything and can put it into practice.
No comparison to other trainers – in a class of its own! He knows every single one of us on the team personally. Our closing rates speak for themselves. What Heiko promises, he delivers – and even throws in more on top.
With all the sales nonsense out there, I'm really glad I work with Heiko. From the very start it mattered to me to have someone by my side who looks after me completely. I can absolutely recommend Heiko.
Heiko is a trainer who not only conveys sound sales expertise, but is also there with empathy and genuine passion. Thanks to his valuable tips, I was able to improve my sales results in a short time and I feel more confident in sales than ever before.
A very pleasant and at the same time helpful conversation with Heiko. What I found especially strong was that he didn't just talk about sales in general, but immediately identified and solved a concrete problem of mine. That's exactly how a consultation should be.
Heiko just took away a lot of my „fears“ over the phone. His online academy is brilliantly structured and packed with an astonishing amount of content. He can show you the way, but you have to walk it yourself – and the journey is worth it.
Ever since I met Heiko, sales has been genuinely fun! Over the last three years our revenue has grown massively and I now do sales with a calm I never thought possible before.
I signed up for the 2023 advent calendar and got a great insight into the world of sales. I really took away a huge amount. I can only recommend it to anyone who wants to grow and develop.
