Yep, totally possible.
The 6-month entry rule only applies if you hold a UAE residence visa. But you can fully own and run a Dubai company without a visa, especially through setups like RAK DAO, IFZA, or even a mainland LLC (if structured correctly). In that case, you don’t have to enter the country at all.
Also, you don’t need UAE residency to︀ open banking elsewhere, many just connect their Dubai entity to an EMI account in Europe,︁ which works fine for payments and operations if you're not dealing in cash-heavy industries.
Some structure things, with a nominee if visa presence is needed for local banking, but in︂ most cases, it’s not necessary if you're set up properly.
I’ve gone down this road︃ myself, just wanted to drop a clear answer since this comes up often.
