About

SentryKit is the Amazon Seller Intelligence platform — a real-time monitoring layer that watches every signal across your Amazon catalog and alerts you the moment something changes. 25+ alert types cover Buy Box ownership, hijackers, price moves, suppressed and suspended listings, stranded inventory, sales velocity drops, review spikes, listing-content changes, and performance signals like Best Seller Badge and Amazon's Choice. Every alert ships with full context — what changed, who caused it, and what to do — within ~90 seconds of the event. SentryKit distinguishes Buy Box Lost from Search Suppression, and enriches hijacker alerts with seller profile, fulfillment type, and feedback score.Delivered where you work: email, SMS, Slack, Microsoft Teams, webhook, or dashboard. Every marketplace (US, CA, UK, EU). Use it alongside any repricer or AI agent — SentryKit is the intelligence underneath. From 1 ASIN to 1,000 across unlimited seller accounts.
