What I'm saying is in theory if somebody is willing to personally build a huge project that should deliver enough revenue to the company to more than pay for the difference. If everybody is willing to work twice as hard as 9-5 worker the company could 10x or 100x, isn't that the whole premise of startups?

Of course not all companies are poised for hyper-growth and are just in maintenance mode or dying, and those places probably don't have much use for people who will build extra hard.

So to answer your question, really the theoretical upward limit is how much value you can generate. Imo it's the opportunity for any great manager to say "Let's meet all your deliverables for the quarter, then I'll talk to the business team and see if there's an extra project for you"
