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!

This book was so good that I read it in ONE day!
Format: Kindle
This book was so good that I read it in ONE day! Ra'anan Cohen shares all the details that most people never talk about about VC/PE/IPOs in the startup world. I found it highly insightful and give kudos to the Ra'anan for the authentic sharing of his story. If you're in the business world, get this book now.

Silicon Valley drama with legal INSANITY
Format: Hardcover
This book started very interestingly. About 30% of the way through it, I hit a lull and started reading another book for a few days. I then decided to come back and HOLY SMOKES what a ride! Lately I’ve been devouring Silicon Valley startup bios and this one seemed like an intriguing tech story. Little did I know, the amount of ups and downs, struggles for funding, and INSANE legal battles were absolutely riveting. It was very inspiring for an aspiring founder. Thanks for the awesome book! I’m the kind of reader that will leave a book unread, but this one was too good to put down! Highly recommend!

The ‘Monkey Business’ of Israeli VC - Brilliant, Sharp, and Fun
Format: Audiobook
I loved this book. It offers a refreshingly honest and gripping portrayal of an entrepreneur’s journey, told with sharp suspense and a great sense of humor. The tension builds beautifully throughout, and I found myself unable to put it down (read it cover to cover in just a few hours). It’s a brilliant book and, in my view, the ‘Monkey Business’ of the Israeli VC ecosystem.
