Critical: Poor data quality and non-compliant records are actively creating revenue leakage and compliance risk. In initial data bake-offs, companies typically see up to a 70% uplift in data accuracy with Cognism.
At risk: Your foundations are in place, but without intervention, data decay will start to impact performance. Benchmark your current gaps and quantify the uplift achievable with higher-quality data.
Optimised: You’re in strong shape. Now it’s about fine-tuning regional coverage, decision-maker accuracy, and reachability. Even high-performing teams typically expect up to 30% incremental uplift versus their existing provider.
