What is the ROI?

Three places. First, the cost of every bad external hire your verified internal slate prevents (Bidwell finds external hires get paid 18 to 20% more and underperform for two years). Second, the cost of every technical mis-hire your decision-grade scorecard catches before the offer (1.5 to 2x salary, per SHRM). Third, the retention lift from internal mobility (LinkedIn finds 41% longer tenure at high-mobility companies). The ROI compounds because the signal does.
