... but actually it sucks to have a lot of employees, and you should be proud of how few employees you have.

In YC experience, 2 or 3 co-founders seems to be about perfect.

You don't need to make the structure complicated, in fact you shouldn't. All you need is for every employee to know who their manager is.

You want to think about what is the path for my first 10 or 15 employees going to be as the company grows.

Every thing at a startup gets modeled after the founders. Whatever the founders do becomes the culture.

You really want to know your cofounders for a while, ideally years.

As long as you keep doing the right thing and have the best product, you can beat the bigger company.
