Karlie Kloss: "It’s an amazing book on the beginning of humanity. It’s scientific but also philosophical."

Joe Rogan: "Great book... Fucking fascinating... Very enlightening."

Patrick O'Shaughnessy: "This book was so entertaining and useful.

It provides a concise history of humankind and outlines why we have the psychology we do today (this part is great for thinking about investor behavior)."

Changpeng Zhao: "[This book] gives me a greater perspective about how humans emerged and why we behave the way we do."

Daniel Ek: "One of the most-talked-about books of the last couple of years, and for good reason.

Both sobering and conservatively optimistic in equal measure, it seems even more relevant for us at the moment to learn from our socio-anthropological history."

Anthony Pompliano: "One of the best books I read in 2017"

Naval Ravikant: "An orthogonal and clinical examination of the human animal, from the beginning to now.

Humans are story-telling alpha predators that killed the competition and domesticated the survivors. This is our story, and it's not all pretty."

David Sacks: "Yuval Harari’s Sapiens had a big impact on how I approach VC. The theme of the book is that humans obsess over narratives.

So I try to focus on product and metrics as a way to get to ground truth, as opposed to over-indexing on the pitch, which is mostly a story-telling event."

Melinda Gates mentioned this book as one of her 11 favorite books.

Bill & Melinda Gates: "Think Again is a must-read for anyone who wants to create a culture of learning and exploration, whether at home, at work, or at school."

Arianna Huffington: "A must read!"

Bill Gurley: "Historically important book that will hopefully stand as a critical catalyst to change in our industry."

Melinda Gates: "For decades, powerful men have responded to sexism in tech by saying, “It’s always been this way.” What they mean is, “It will always be this way.”

Michael Bloomberg: "An important new book about gender equality in Silicon Valley"

Melinda Gates: “Hans Rosling tells the story of ‘the secret silent miracle of human progress’ as only he can.

But Factfulness does much more than that. It also explains why progress is so often secret and silent and teaches readers how to see it clearly.”

Bill Gates: "Factfulness is one of the most educational books I’ve ever read."
