Study of 21,559 U.S. Firms: Heavy AI Investors Grow Jobs ~10% in 24 Months

A new study of 21,559 U.S. companies finds that firms making the largest AI investments grow their total headcount by about 10% over the 24 months following adoption, while low-intensity adopters show no statistically significant change in employment. The research is based on a working paper from Ramp Economics Lab, the research arm of financial operations firm Ramp, titled "A New Look at AI's Impact on Jobs: Firm-Level AI Spending and Workforce Adjustment" (by Ara Kharazian, Lisa Simon, and Ryan Stevens, June 2026). It links Ramp's card and bill pay data on AI vendor spending with workforce records from Revelio Labs.
