Palestinian employees process data on their laptops at Unit One in Gaza City January 15, 2015. In nine years, Gaza-based IT entrepreneur Saady Lozon and his partner Ahmed Abu Shaban have transformed their firm, Unit One, from a tiny outfit in a single room in the blockaded Gaza Strip into a successful business with clients in Europe, the United States and the Arab world. They can't leave Gaza easily, but they can develop applications for Web and mobile devices online and provide international clients with data-management services, competing with firms in India and elsewhere.
