You never want to be in a place where an employee has vested 3 out of the 4 years of stock and they start thinking about leaving.

You should always know how you're doing against your metrics. You should always have a weekly review meeting every week.

Another way of looking at this, is that the best companies are almost always mission oriented.

We hear again and again from founders, that they wish they had waited to start a startup until they came up with an idea they really loved.

It's really easy to get PR with no results & it actually feels like you're really actually cool, but in a year you'll still have nothing.

In general, it's best if you're building something that you yourself need.

As the company grows and about this 25 or so employee size, your main job shifts from building a great product to building a great company.
