Your corporation should start with enough cash-on-hand when you incorporate to let you buy a warehouse, an office, a sales desk, a factory line and hire a worker for each with a decent chunk of change left over for experimenting. If that's not the case then something is very much broken

That would be great! A simultaneous layer that interacts with the main might make climbing the prestige system and REP later again easier and different enough to feel engaging.
But no, I incorporated with zero dollars. I've dumped seven prestige bonuses into Corpo and done some REP/Mission free money making dives, caching 10k at a time until I could afford an office, warehouse, sales staff member, two production machines, and a pair of line workers. So I think I'm around the intended start point now!
