What works/worked for AngelList isn't going to work for your team necessarily. Choose your culture and incentives wisely and use an approach that helps you to solve problems. If the consequence of shipping software that has an unknown and undesired behavior could cost your customers millions of dollars an hour you should probably invest in a team that is familiar with formal methods (or some other approach to ensuring you ship the right thing). Shipping the first thing that works on your dev machine that passes a few unit tests isn't generally sufficient when property or people are on the line.
