When a competitor goes dark,
that's your window.
Competitor stockouts are some of the highest-ROI opportunities in e-commerce. The demand is already there — the seller just vanished. We monitor inventory signals across marketplaces and alert you within hours so you can actually capture it.
More than "out of stock"
Marketplaces rarely say "OOS" outright. We read the signals that actually indicate low or zero inventory.
Unavailable / OOS flags
Direct platform indicators — with context on whether it's temporary or permanent delisting.
Delivery delay spikes
Sudden shifts from same-day to 7+ days are almost always an inventory problem.
Quantity caps
Amazon's "max 2 per order" trick — the classic signal of constrained stock at the seller.
Seller rotation
When the main seller disappears and an FBM seller quietly inherits the listing, something's off.
Price surges
A 40% overnight price jump is often a stockout signal from the algorithm, not a real pricing decision.
Location coverage drops
A SKU available in 10 pin codes yesterday and 2 today? That's a distribution hole to fill.
