That's the neat part: the money doesn't have to exist at all.

And once you go through enough hops and convince the world that this thing which your company happens to be pioneering will forever change the world and everyone will use it the money circle isn't even relevant because the entire goal was to make your stock prices skyrocket and now you're valued at ridiculous levels!

Just make sure to get out of it all before any Investor actually wants to see real profit being made.

You get more money in, so you have higher revenue. Your spending also increases by an equal amount, so your profit is unchanged.
