The natural state of a start-up is to die; most start-ups require multiple miracles in their early days to escape this fate.

One thing that often disrupts momentum and really shouldn't is competitors.

I think as a rough estimate, you should aim to give about 10% of the company to the first 10 employees.

Just put a little pin in your mind: when you cross 50 employees, there are a new set of HR rules that you have to comply with.

Most startups are not nearly focussed enough. They work hard...maybe, but they don't work hard on the right things.

The startups that do well are the ones that are working all the time.

... the thing we see wrong with YC apps most frequently, is that people have not thought about the market first and what people want first.
