Recommendation
During my cooperation with Jan Sergienko I have experienced him as very professional and in his field of expertise - the creation and marketing of books, as well as the support of these processes - as extremely capable and experienced. Jan is a person who, in a business context, says very clearly and directly what he thinks and why. This makes working with him not only pleasant, but also very efficient and goal-oriented. Whoever works with Jan Sergienko can be sure of achieving the goals he has set for himself. I can definitely recommend him as a contact person for the above-mentioned topics to anyone who is looking for advice or support in these areas. Overall, I look back extremely positively on the time we spent together and am grateful to have gotten to know Jan!

Jan Sergienko has been my client with his books for over two years now. The cooperation with him could not be better. The books I have edited for him so far have all been very interesting. I always learn something new myself, as it should be, because the topics of his books are so wide-ranging.
The process of an order for him runs smoothly, from the placing of the order to the payment of the invoice. Should there be a query - which is rare enough - he can be reached very quickly, so that we can solve small problems immediately.
Communication with Jan Sergienko is always very stimulating. He is a person who can also listen to others and has a great deal of knowledge himself.
I can only recommend Jan Sergienko and his company.

A master of his trade! Jan knows exactly what is important when you want to publish your own book and do it successfully and with high profit!

Thanks again for the great cooperation Jan! I realized every day what a complete professional you are and how little I actually knew about how to make a book successful!

My business has already scaled up very well and my investment was already out a few weeks after Jan's assignment.

I'm excited for the future and look forward to even better results now thanks to my new book!

Absolute recommendation from me!
