During my studies I was an out of town person, i moved to city for studies leaving my family behind, I quickly found out that I was not alone there were quite a many student coming from remote areas and other cities.
This holds true for all major metropolitan cities of Pakistan, the hardest job for these people was getting a residence quickly, Arzi Rehaish Tries to solve this problem.
The concept is simple, it is basically a property site like any other but has a niche, its focusing on out of city students and professionals, The site is also simple, lists down the available accommodation, lists down students/professionals with their needs and you could use the platform to send a message to the prospective tenant or landlord.
Again as i said the innovation is not in the site it self but the fact that instead of being an ordinary site they are focusing on a niche, which is a brave and good thing to do.
Now All they need is to quickly create content and get people to their site, i would suggest investing some time in SEO, working with universities and letting them know about their existence, some times an outside student has no clue what so ever where to start looking so he contacts university administrations. If some how they can hook them up it will create traffic for them. Good luck to them.
