"Sentinel caught a competitor slashing prices on our top ASIN at 2am. By the time I woke up, the alert was already in my inbox. I repriced, held the Buy Box, and had a record day. Worth every penny."
"We were constantly losing the Buy Box and couldn't figure out why. Sentinel showed us that three competitors had been quietly undercutting us by $1–2 for weeks. Price history alone paid for itself."
"The daily Slack digest is part of our morning standup now. Everyone sees what moved overnight, who repriced, and what Gordon AI is recommending. It's changed how we manage pricing completely."
