Apparently, I was the first to join the Masterclass. I am an IT-professional and work alone. I had previously read the book 'Avoid Tax, Now!' from Yulia Keating. A fascinating book, but I needed further assistance to implement a low-tax solution. The Masterclass was an eye-opener. The first part is all about practical points and regulation that makes your life difficult in the international business scene. To be honest, that part was a bit boring; nevertheless, they kept it interesting and condensed.
The second part with the 8 solutions is quite fun. They explain the solution and give a detailed example with numbers. It feels like you are in a buffet where you can choose the menu that is best for you. I binge-watched the modules over a few days. I almost did not take any notes because the handbook has it all. I liked the fact that the manual is in bullet-point style, so it is easy to find or double-check something.
In my case, there were 4 out of the presented 8 solutions that could work. I doubted between 2 of them. In the end, I had a Skype call with The Shark, and together we selected the most beneficial option for my company. Actually, the solution I will implement was not one of the two I had in mind. So, the personal one-on-one call with the Shark is indeed valuable. I also have to give him credit because we were on Skype well over an hour. He was very generous with his time. In return, he asked me to do an elaborate review of the Masterclass.
The cost of the Masterclass is irrelevant since I am about to save 29'500€ in tax the next year, so a 620€ investment is well-spent.

In 2018, I paid 62% of taxes and social security combined. At the same time, my country opened borders to busloads of immigrants. Immigrants that receive housing, food, healthcare, and in return, put our cars on fire and act violently towards us. I decided I did not want to sponsor this any longer. However, my local accountant was useless; he had no creative tax-saving ideas, let alone international. His only priority was to fill out the tax declarations and tell me the amount of taxes to pay. I stumbled on the website www.avoidtax.online and started to watch all free content from beginning to end; the tax case studies, the entire YouTube channel, the free eBook to make sure this program was not a scam. I also got in touch by e-mail and booked a free Skype call. He referred me to the Masterclass, which I took. It's all well-structured and organized, no long-winded useless information, just what is essential and straight to the point. Actually, some modules are so condensed that I had to watch them twice. The manual is handy as a reference. I also appreciated that there is no time wasted on psychology, mindset, and motivational topics. It's about lowering taxes, point. I now have 2 workable solutions to choose from, which I will implement in the coming months. I have not yet read the free eBooks, so I can not comment on them. With projected tax-savings of +/-35'000€ per year, the price of this Masterclass is a no-brainer. I can highly recommend it.

We have a consultancy company in a high-tax country. For many years we were looking for attractive tax-optimization solutions. The problem we faced, was that it is possible to find crafty advisors, but they only know one solution, their product. They will tell you the benefits of moving to Monaco, or setting up a company in Poland, or go offshore to Belize. But no-one was able to present and compare different low-tax solutions so that we could pick the best option for our specific business. This Masterclass gives you eight options, which is more than enough for anyone. The Masterclass is top-notch. The Shark really knows what he is talking about - well explained, detailed, and organized. He also has a broad network of pros working behind the scenes.
Since our company has quite some turnover, we took the Masterclass and booked several additional brainstorm sessions. The guy seems to have a limitless amount of valuable out-of-the-box-ideas, which pay themselves back right away. 
In total, we paid the Shark around 1'700USD for the Masterclass and the brainstorms, but we are about to save 84'000€ in tax in 2021, which is roughly 2'000€ of savings per working week. 

We are sure we will use his services in the future to monitor the growth of our company. I think everyone should do the math on his individual business situation and work from there.
