Why Sofia matters for lead generation
Because the target market is a low-cost EU vantage point for testing, the data you collect is only trustworthy when it comes from local vantage points. Geo-restrictions, currency logic and regional inventory all key off the visitor's IP — get that wrong and every downstream number from your lead generation run is skewed.
