- Lost and Founder - the founder of Moz shares his advice and experience from building a 40M/year company. I found the things he says about building a startup extremely insightful and practically useful. Reading it feels like having a dinner with a friend who shares with you the things he has learned in a very honest, down to earth way. Highly recommend it.
- Rationality from AI to Zombies - probably the most influential book I've read in my life, profoundly changed the way I think. It's a collection of LessWrong essays on science and rationality. (recently they've released an an audio version by the way).
- "A Short History of Nearly Everything" and "Our Mathematical Universe" - two general popular science books I'm enjoying a lot. Haven't finished reading them yet, but so far they're brilliant(and very easy to understand, authors do an amazing job explaining complicated things in a simple, accessible way).
- Hacking Growth - an AMAZING book on "growth hacking". It provides a framework for marketing a startup, gives a ton of practical advice and specific tactics. It breaks down step by step how startups and big tech companies grow their products. Most of the books I've read on the subject were bullshit, but this one is absolutely fantastic, can't recommend it enough.
Other great books I should mention: This Idea is Brilliant, Actionable Gamification, The Design of Everyday Things, The Master Algorithm (great overview of machine learning techniqes), Springfield Confidential (fun behind the scenes from one of the writers on Simpsons), Homo Deus(from the author of Sapiens).
