A real masterpiece
Format: Paperback, Format: Paperback
One of the best books I have read in years. A real masterpiece. I read most of it on a flight from Sacramento to NY and then forgot the book in a car from the airport to the hotel... I had to wait a week before getting a second copy, which I could not put down until 1:30AM when I finally finished it. I can’t wait for the movie. A wonderful story of the life of a startup that anyone in the industry can easily relate to. While many of us know the real story behind the true events, the book keep you in full suspense the entire time. I think the author has finally found his true calling 😉

Highly recommend the book!
Format: Hardcover
I recently purchased the book.
I thought it would be nice, but I didn't expect to read it really quickly.
It turns out I didn't leave it, I didn't receive it with other books, I strove to finish it and I also enjoyed every moment.
The author - Raanan Cohen - is a man who made an exit.
It doesn't matter how much, but a lot.
So he can be calm about Nino's financial future.
But the book is not a docu.
It may be one-to-one with what happened in reality, but it is fictional and exciting and fun.
It is also a bestseller.
It doesn't come off the bookshelves, doesn't come off the sales charts.
You would expect a person that everyone wants to know more about now to be very distant.
But Raanan Cohen answers within minutes.
This is repeated in the book as well.
His character Rom Carmeli is insanely available.
But I didn't think it was about the truth.
How can an entrepreneur who has the VP of Coca-Cola, the number 3 person at Wal-Mart, and the owner of Colmobil text him and ask for a meeting - can he even answer people he doesn't know like that?
But in the end, it happens.
I sent him an email and he replied within minutes.
I sent him a WhatsApp and he replies almost seconds later.
Stressing!
I told my wife that I was afraid to send him a message. He just replies immediately and that's it.
There's no pause, no hold, he's online with you.
I recorded a podcast with Raanan.
The one thing that struck me was the availability.
It's eye level.
It's the lack of fashion in the best sense of the word.
A person who could filter without a problem, just gives you a good feeling.
Refreshing Cohen and Rom Carmeli I'm learning that a nice person doesn't have to be a sucker.
You don't have to write or talk because it's unpleasant.
If necessary, the conversation ends.
But an important / rich / powerful / ordinary person - can simply be a nice person And available.
Highly recommend the book!
