I had a look at their website.
I always think it's odd when the "About us" section of a website gives no information about the owners or management.
It also looks as if they are not regulated in Qatar, which means that you have no come-back if things go wrong (i.e. no Ombudsman to complain to, and probably no professional indemnity insurance).
The investment products that they sell are the same toxic crap that deVere and others sell. You know that when you see the words "appropriate tax wrapper" which always means a high-commission insurance policy.
I would say avoid and either read the excellent book recommended by Frequentflyer1234 above or go to a regulated fee-charging independent adviser in whatever country you come from.
