Full Answer

During technical due diligence, acquirers assess four dimensions: accuracy (does the data reflect reality), completeness (what percentage of events are captured), ownership (is it in your warehouse or locked in a third-party platform), and portability (can it migrate post-acquisition). They examine data freshness, collection methodology, and compliance documentation. Companies scoring poorly face 10-20% valuation discounts. In extreme cases—undocumented data, no historical records, platform dependency—poor data quality becomes a deal-breaker entirely.
