Start by purchasing ten managers that will run ten different businesses. You will need to be patient, as the next ten managers will require 10 duotrigintillion moon bucks each (100 dutrigintillion in total). These also make the next levels 25% cheaper (which is much less than the 99.999% cheaper on Earth). Consider displaying the cash per second to optimize your spending to the most profitable businesses. Note: You do not need Louis Fittui (manager 21), who costs 5 tredecillion angels to qualify.
