Foreign investors are continuing to contribute in a big way to Dubai Silicon Oasis (DSO). The technology free zone attracted investments worth AED 3.6 billion last year, with foreign-backed projects accounting for half of that. There’s also been a 38% increase in the number of companies operating out of DSO, while its revenue grew 16% year-on-year. European and Asian firms currently form the bulk of companies within the free zone, with most working across technology, telecom and commercial sectors.
