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

You should be giving out a lot of equity to your employees.

Why couldn't it have been done 2 years ago, and why will 2 years in the future be too late?

The single word that matters most I think to keep the company productive as it grows is alignment.

Most founders have not managed people before, and they certainly haven't managed managers.
