Dubai investors (Khaleeji, Indian, or Russian) are looking for a "dhandha" - not a business.
Any story that can't be easily translated into an "arbitrage" or "commodity" play just isn't going to land with them.
Abu Dhabi has fairly good growth stage investors, but that's also because they tend to let the money managers and investors remain in London, SF, NYC, etc.
You're better off remaining in the Indian market, or if you want deal flow abroad, then building relationships in the US, ASEAN, UK, or Australia unless you're a "VC" who's trying to land a Dubai Golden Visa in order to evade taxes back in India (these kinds of personas tend to overlap with the kinds who run real estate or export/import "dhandhas" back in India).
