Increasingly, we're not citizens, fans, or patients anymore; we're a resource being mined. - Eric Ries

It is also the right way to think about productivity in a startup: not in terms of how much stuff we are building but in terms of how much validated learning we’re getting for our efforts.

The two most important assumptions entrepreneurs make are what I call the value hypothesis and the growth hypothesis.

It’s also important that the word innovation be understood broadly. Startups use many kinds of innovation: novel scientific discoveries, repurposing an existing technology for a new use, devising a new business model that unlocks value that was hidden, or simply bringing a product or service to a new location or a previously underserved set of customers. In all these cases, innovation is at the heart of the company’s success.
