Where to emigrate, SND a young startup?

Antarctica — no taxes, no competition, and most importantly — nepahannoe market :)

Emigrirovat not startups, and people. Accordingly, each country has its immigration laws. Unrealistic just pick up and leave for life. Must be either starting capital, or investor, or to work on site or remotely.

The question should be clarified: "that means favorable conditions?"
For me, Ukraine — mega-favorable for it given the large field for the implementation of the it services against the background of General technological backwardness :)

and themselves, then where? Russia?
and a start on the market? CIS or English?
what are the goals of migration? developed economy? optimal taxation (so maybe offshore?)?

Germany, Canada. There it is possible to immigrate though.

Ireland, there is an innovative centre SKOLKOVO type gives good benefits

Well, needless to USA, Canada, Australia, possibly the world Bank — at least meet two conditions: 1) a favorable environment for start-UPS and it 2) have the opportunity to status in the presence of normal story of a startup. There is a famous study by Startup Genome, about the most interesting parties, but I think from the us all behind. But in the States the problem — it's hard to get the status. They're the draft law consider, but what it really is — hard to say.
