Should I sign a GCC-wide master franchise agreement first?

In our view, no — prove one flagship first. A master agreement priced before a single local unit has produced a real P&L is priced on projection, and the risk lands on whoever signs it. One flagship, run for enough quarters to show the re-based economics hold, gives you evidence to license against — and a materially stronger negotiating position. Stage the territory: one city, then one country, then the corridor.
