e.g. on line Open Data institute, Big Data Startups, or Midle East Open data source but I´m not at all sure that these data base provide exactly what you need
The Global Entrepreneurship Monitor compiled by Babson College et al. includes data from more than 100 countries, some of which are in the MENA region (e.g. Egypt, Libya, Oman, Morocco, etc.). The report is available online.
It is indeed quite hard to find reliable data on start-ups in the MENA region. Who may be able to provide you with at least some reliable data are the various VC and private equity associations (i.e. EPEA in Egypt; http://www.epea-eg.org/). What I find quite interesting is the Website http://www.startupranking.com/countries where you find an overview of selected start-ups by country (mainly covering Internet start-ups). The number of new businesses registered per country can be found at http://data.worldbank.org/indicator/IC.BUS.NREG, but of course the data don't cover the informal sector where most of the startups in the MENA region start.
On the topic of financing you may find quite interesting the Background Note on "Options for New Financing Mechanisms for the Middle East and North Africa" published by the World Bank Group and the Islamic Development Bank in Sept 2015.
Were are many other data sources but all of them are quite fragmented and none of them will provide you with a full data set on the MENA level.
It is indeed very hard to find such data. However, you might consider extrapolating some lessons from emerging economies. Here is a study that I did earlier:

ABSTRACT: Given the increasing importance of Asia, the purpose of this special issue is to broaden the scope of our understanding of New Product Development (NPD) by going beyond the traditional Western research settings and looking at how new products are developed in Asia. This paper introduces the special issue on NPD in Asia and identifies key patterns of similarities and differences between Asian and Western NPD practices. The paper highlights key similarities and differences in the areas of organizational/top management support; technological proficiency; customer/market orientation; information sharing; cross-functional interface; entrepreneurship orientation; NPD strategies; innovation orientation; contingencies of innovation orientation; innovative marketing strategies; NPD process; appointment of project managers; rewarding team members; success rate; and cycle time.
