I build the scrapers the data vendors run on, and I need to tell you what you are actually paying for
Short summary
Contact data vendors market 'fresh' data but actually sell month-old snapshots. They systematically skip the expensive verification work of checking who still works where, hiding this through emphasis on coverage rather than accuracy. Ask vendors what percentage of their 'current company' fields they reverify—their answer reveals whether you're buying current data or old photographs.
