A startup is a human institution designed to deliver a new product or service under conditions of extreme uncertainty.

The hardest part is the grueling work of constantly being wrong.

Zero invites imagination, but small numbers invite questions about whether large numbers will ever materialize.

Most companies are busy making their products worse, not better. Updating is almost always a disaster.

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.

The only person who can put you out of business, in the early days, is yourself.

The grim reality is that most start-ups fail. Most new products are not successful. Yet the story of perseverance, creative genius, and hard work persists.
