They bet on hiring cheap people in Bulgaria and finding that the supply is not infinite, so they are trying to source some. All the companies with offices in Bulgaria, Romania, Ukraine etc are looking for cheap workforce, preferably very skilled and experienced but accepting to work for 1/4 to 1/8 of SV salaries. These days even India is quite expensive and the value proposition (cost-benefit) used to be better for Eastern Europe (similar or a bit higher cost, much better quality and results), so they are hiring in this region as much as possible.
