The case study earns its Breakthrough tag by anchoring the headline in a concrete headcount number that moved up and stayed up. The compliance angle gives the story a second dimension worth noting: Adyen operates under banking regulation, which raises the stakes for adoption gaps in a way most ATS stories do not. The 95% in-house hiring figure is a useful supporting metric that shows structural change, not just volume.
Pairing a growth number with a regulatory constraint sharpens the stakes. Most recruiting case studies stop at headcount or time-to-fill. Framing adoption failure as a compliance risk, not just an inconvenience, makes the usability win feel consequential rather than cosmetic.
