How to scale a software development company?

As a software engineer for 10 years+ I'm thinking about starting a software company, however, I'm not quite sure how I would scale it.

In other words, In the past I've worked with a designer/frontend guy and maybe one other backend guy to complete projects. If I were to start a software development company, how would I scale it?

Essentially, I'd be getting the contracts - I have maybe one or two solid frontend and backend guys. But I can't help but think that I'd be there micromanaging them constantly and as more projects come in, I don't know how I would balance it all without becoming overwhelmed.

Any suggestions?

Thanks!
