In a rush to build the next amazing product, a lot of startups develop right past the features they have to be great at.
Always wanting to do «the new thing» it is incredibly hard to keep a team focused on delivering less features, at really really high quality. Because to do this, you have to work on the same few features over and over and over.
Nail the basic features and you will have a solid product. Miss them and customers will punish you.
