Books I recommend:
Start small stay small - How to build a realistic software business.

V is for vulnerable - A cute book on the attitude you need to survive as an entrepreneur.
Lean startup - The book that kicked off how to run a startup
Traction - A treatise on customer aquistion strategies or how to get traction.
Books I'm reading now:
Zero to one - In progress looks great.
Paul Graham - Paul is the founder of y-combinator and his writings defined the startup industry.
Brad Feld - One of the other best loves VC's. Often talks about funding, very interesting.
We don't sell saddles here - A treatise from the founder of Slack.
How to think about MVPs - A classic picture of how to build an MVP of a car.
Commonly recommended books I could not finish:
Startup Owners Manual - Steve Blank - Steve is a smart guy (Mentor of Lean Startup Guy) and arguably the inventor of customer development,. However, I find his writing and this book meandering. I wanted to read this book but could not finish.
