Ran the CSV through our deduper first. Dedup pass only flagged 1.2% — cleanest dataset I've worked with. Bought it for a United States calibration service provider market-sizing project. Genuinely useful.
Live-tested 30 random rows before committing. Email coverage is the highest I've seen for United States B2B data. Bought it for United States's calibration service provider segment specifically. Will be the default vendor for us now.
