What should a launch simulator calculate without pretending to predict virality?

Build the simulator around controllable inputs: account scope, content quantity, known unit costs and a chosen observation plan. If you include traffic or purchase scenarios, label them as user-adjustable assumptions and show how the result changes with them.

Do not give a precise-looking revenue output the authority of a forecast. The useful result can be a budget, a required break-even outcome or a comparison of operating plans. A transparent model helps a founder ask better questions even when future performance is unknown.
