To me, it's more of a "scale-up" and they are not a non-profit, so things move quickly, and sometimes processes are still being built while you are running. If you prefer very structured environments with everything perfectly documented, this might feel different than a typical corporate space.
Ramadan season is high energy and high pressure. It requires stamina and strong planning. Time zones can also be challenging since the team is spread across multiple countries.
Overall, if you are motivated by mission and comfortable with a fast pace, it can be a very rewarding place to work.
