“We caught a $12K overspend on a Friday night that would have gone unnoticed until Monday. AdPace Sentinel paid for itself in the first week.”
Sarah Mitchell
Director of Paid Media, GrowthForge Agency
“Managing 40+ client accounts used to mean constant manual checks. Now I get a Slack ping only when something actually needs my attention. Life-changing.”
James Kowalski
Senior PPC Specialist, Meridian Digital
“Our conversion tracking broke silently for 3 days before Sentinel detected it. Without the alert, we would have been optimizing against garbage data for the whole month.”
Priya Desai
Marketing Manager, TechLadder SaaS
