# Read the source documents, because official classifications lie

Public tenders in Romania carry official CPV codes, a taxonomy of roughly 10,000 subcategories, and Mihai found the labels wrong often enough to be dangerous, including food accessories classified under laptops. So DataDriven ignores the metadata and reads the actual tender documentation, OCRing PDFs and scans, then classifies everything against a hand-built taxonomy of about 180 categories that mirrors how companies really describe their work. That is the product's core advantage: competitors who filter on the official codes inherit the errors, and their users miss winnable contracts. Whenever your product sits on top of someone else's data, ask whether the labels are trustworthy or just convenient. Going to the primary source is expensive, which is exactly why doing it becomes a moat.
