EntreSim — Stress-Test Your Startup

Start a run

Upload the workbook you built from EntreSim_Template.xlsx. The simulator validates it, then replays real historical macro data against your plan one year at a time. The only randomness is the shock process, controlled by your assigned seed — every run is reproducible.

Halting a run and fixing your plan? Upload the fixed workbook as a new run — every attempt stays on record, and submitting a failed first attempt plus a repaired second one is exactly what the assignment asks for.
