Market
Jeddah, properly
"The GCC" is not an audience. It is a line in a procurement template.
Six countries, four currencies, two working weeks, a dozen dialects, and a regional plan that treats them as one place because the budget was approved as one number. I have written those plans. They are elegant on the page and they die on contact with a Tuesday.
Here is what a regional plan actually buys. A creative that is inoffensive in six markets and loved in none. A media schedule tuned to the biggest population, which quietly becomes the whole plan. A launch that lands in Riyadh on a working day and in Dubai on a Saturday. Reporting that averages one success and two failures into a mild disappointment nobody can act on.
Now take the same money and put it into Jeddah. One city. One dialect, one weekend, one set of neighbourhoods you can name, one summer that empties it and one season that fills it. You can visit the shops that stock you. You can read the reviews in the language they were written in. You can find out, within a month, whether anyone here wants the thing.
The arithmetic agrees before the culture does. A budget that is thin across six markets is thick in one, and thick is where learning happens. Everything you find out in Jeddah travels. Almost nothing you find out from a regional average does, because a regional average did not happen anywhere.
Serve one city as though it were the only city. Then, if it works, the second city will tell you very quickly what was Jeddah and what was you.
Most regional plans fail because they were built for a place that does not exist.
