About Me
Marcin
Osman
Creator of the business publishing house Osmpower.pl, publishing bestsellers by authors such as Tony Robbins, Gary Vaynerchuk, Wim Hof, Tim Grover and many others.
In my career, I have created sales and marketing projects for international brands, and for over 5 years, I have been focusing on 80% of my own projects (such as osmpower.pl).
I devote the remaining 20% of my time to working with entrepreneurs and companies that, thanks to my own competences, want to sell more and carry out effective marketing activities.
I promote the hustler attitude and the thank you economy (economy of gratitude), both of which are the foundation of our entire philosophy of business activity.

About me
I am the author of 14 books
I am an entrepreneur, sales practitioner, author and co-author of 14 books, and a bestseller publisher.




I have succeeded and failed many times, and I have shared my experiences (both good and traumatic ones) in audio, video and text form. I know perfectly well what victories taste like, but I also remeber the painful lessons of business humility.
I have conducted over 200 webinars and several hundred facebook live events, where I shared my knowledge and experience in the field of sales, marketing and self-publishing.
Thanks to our self-publishing courses, which I run together with Kamila Kruk, over 50 books have been published.
