Amadeo Brands

Code Analyst

After completing my technical and economic studies, I successfully launched and sold a number of companies (mainly in the digital domain). This was followed by a period in which I was active as a technical delivery manager for the private equity sector, after which I went to work as an IT Consultant and Mendix developer.

In 2014, I received my first Bitcoins for freelance development work I was doing for a Singapore customer at the time. Since then, I’ve delved deeper into cryptocurrencies and then mostly the technology behind it. Through this research, I have become increasingly convinced that blockchain is the next digital revolution.
With my technical and economic insights, I have a unique look at the cryptocurrency market. By joining Cyber ​​Capital I am able to put this knowledge into practice. I do fundamental and code analyses to see which cryptocurrencies can actually live up to their promises.


Boudewijn Rooseboom

Founder – General Manager

After completing my Master’s degree in Economics at the University of Amsterdam in 2003, I embarked on an 11-month, 43,000-kilometer journey from Tierra del Fuego – the southernmost tip of South America – to Alaska. I then moved to Brazil, where I set up the company Stonerose Property that developed social housing projects. During my ten year stay in Brazil I gained a lot of experience with overseas investments, having to arrange for structure, taxation and legislation for both Brazil and The Netherlands.

With this knowledge, I began looking into Bitcoin and blockchain, a few years ago. I find it a fascinating and promising technology, it is still in its infancy and the possibilities are endless. What Cyber Capital is doing now has not been done before. That makes it so challenging. Besides these activities I am currently enrolled in the post academic course for Registered Controller (RC), also known as Certified Management Accountant (CMA), at the Free University of Amsterdam. After all, control generates trust, which is the foundation of every investment.


Jan-Willem Verhees

IT Manager

After my studies Computer Science, with a Master in Embedded Systems, at the Technical University of Eindhoven, I left for St. Petersburg, Russia in 2007. There I worked for five years as a technical project manager and consultant for a Dutch IT company, for which I worked an additional year in Kiev, Ukraine. In 2013, I started the company Orange Sputnik, together with my Ukrainian business partner, in Kiev. We provide the staffing of IT employees for Western European companies. Subsequently in 2015, I founded the Dutch company Flounders BV, with a Dutch business partner in the Netherlands. Flounders provides IT projects including websites, web applications and mobile apps. The development is being done from my current city of residence St. Petersburg, Russia.

My first encounter with cryptocurrencies was in 2013, when the Bitcoin was still at 100 euros. Unfortunately, due to my busy life as an entrepreneur, I have little time to keep me well informed about the subject matter. I therefore believe in the service offered by Cyber ​​Capital, as cryptocurrencies require specific attention to be able to thoroughly understand them.


Justin Bons

Founder – Investment Strategist

I studied political philosophy and history at the University of Auckland. Shortly afterwards I emigrated from New Zealand to the Netherlands in 2013. During this time I discovered cryptocurrencies in which I immersed myself more and more. This led to investing and trading in cryptocurrencies and the creation of a bitcoin mining operation in 2014.

Nowadays, I devote myself full time to cryptocurrencies, doing ‘fundamental analysis’ with a focus on the underlying governance models. Cryptocurrencies require a multidisciplinary approach to understand them, but also to successfully invest in them. I expect this new technology to become more widely adopted, with capital investments making a real contribution to building the infrastructure needed for such greater mass adoption.
Through writing articles and giving lectures, I regularly participate in the public debate surrounding cryptocurrency. I am also a voting member of Bitcoin Unlimited, and an outspoken proponent of larger blocks in Bitcoin. It is an exciting time in history, I am happy to be a part of it and help to further this amazing technology.


Marten Hatzmann

Trading Advisor

After completing my studies in Industrial Engineering and Management Science, I worked for ten years as a trader in the world of agricultural raw materials i.e. commodities. During this period, I spent a significant time in Brazil, the country in which I also got to know Boudewijn, who was active as an entrepreneur at that time.

My interest in cryptocurrencies began initially as an investor. After taking a few positions, I soon realized that there are many similarities between trading in cryptocurrencies and trading in commodities. I was able to successfully apply my professional expertise on topics like analysis of supply and demand, liquidity, volatility, application of technical analysis on price graphs and market psychology.
I decided to join Cyber ​​Capital as an independent advisor in early 2017, because I felt I needed to learn more about blockchain and cryptocurrencies. The combination of both areas brings many new insights to all involved and gives me a unique opportunity to learn more about this revolutionary technology.
