“I joined Sakari’s Unlimited Coaching to work on my first book, and it turned out to be a decisive move. Through the coaching, the focus gradually crystallized into IT consulting—which proved to be exactly the right choice.

Whenever I got stuck, I could book a short call and always walked away with concrete, actionable next steps. There was no hand-waving, just practical guidance when it was needed.

That first book became an Amazon bestseller and marked the real start of my author journey. It, along with its successor, has been used as a university textbook in Mexico and Portugal. I also use the book actively in my own mentoring work, and I’ve received feedback that it should be required reading for new consultants.

Since then, I’ve published two more nonfiction books in two languages, with my debut novel now out and a children’s narrative nonfiction book currently in the pipeline.

I can wholeheartedly recommend Sakari to anyone who wants to publish a book with real substance, creates impact, and opens doors.” >> eetuniemi.net

"Few people have an idea and execute. Even fewer people execute consistently over time. Sakari is one of those few. Sakari is the real deal.  I'm thankful for my friendship with him and highly recommend anyone else getting in relationship with him on a personal or business level." >> IG: troybrave

“Sakari Turunen is my dear friend who challenged me to write and stayed committed until this book became reality. He poured in hours and hours of his precious time to help make sure the project was completed. Since publishing, it has been a joy to see the book become an international success and used as teaching material in multiple nations. I’m truly grateful for Sakari’s support — God bless you abundantly.”

Sakari is a powerhouse when it comes to composing and writing books. He inspired me to write my Amazon best-selling book, Engineering MLOps. He consistently brings strong ideas on how to structure content and present complex topics clearly. I highly recommend working with him if you’re aiming for premium-quality content.
