You mean your standard consulting company that works on a project basis? This isn’t anything new.
I worked for a startup founded by two non technical brothers who brought in an outside consulting company to do all of the work and then they brought in a CTO to bring it in house and I was one of his first technical hires.
You’ll be competing with cheap outsourced developers where only the tech leads and project managers are paid American wages.
You are basically doing staff augmentation which is the fifth level of hell
