How often are the YC application cycles?

I’m about to leave my job to work on a fashion startup with my husband. There are some technical aspects to the business that I am building into products, but my immediate focus is to get his clothing store online.

I know the product(s) I want to build will be compelling, but my concern is not having enough cash to hire a small team.

At what point is it best to apply? After you have a working application environment? After you have 1-2 people on your team?
