What the gap actually buys you

The rate gap between the highest- and lowest-cost regions is largely a cost-of-living and labor-market gap - not a quality gap. Top-tier firms in lower-cost regions routinely deliver work competitive with premium markets at a fraction of the cost.

That said, time-zone overlap, language alignment, and IP protection vary by region. Eastern Europe and LATAM hit a sweet spot: meaningful cost savings with same-day overlap for US/EU clients.

Every cell in the grid above is the count of firms in (place × hourly-rate tier). Firms are placed by their published hourly rate; those without a disclosed rate are not plotted.
