We must learn what customers really want, not what they say they want or what we think they should want.

Products a start-up builds are really experiments…Learning about how to build a sustainable business is the outcome of those experiments [which follow] a three-step process: Build, measure, learn.” “[A startup is] … an organization dedicated to creating something new under conditions of extreme uncertainty.

I asked all of our recruiters to give me all resumes of prospective employees with their name, gender, place of origin, and age blacked out. This simple change shocked me, because I found myself interviewing different-looking candidates - even though I was 100% convinced that I was not being biased in my resume selection process.

I would say, as an entrepreneur everything you do - every action you take in product development, in marketing, every conversation you have, everything you do - is an experiment. If you can conceptualize your work not as building features, not as launching campaigns, but as running experiments, you can get radically more done with less effort.

In a startup, both the problem and solution are unknown.

Every startup has a chance to change the world, by bringing not just a new product, but an entirely new institution into existence.

The minimum viable product is that version of a new product which allows a team to collect the maximum amount of validated learning about customers with the least effort.
