What is your excess worth?
Paste the part numbers you’re holding, or drop a stock list. We’ll check each against the live surplus pool — how many others are selling it, and what it goes for. Free, and we ask for nothing first.
Xcess360 · free on both sides

Your dead stock is someone else's shortage

No subscription from either side. Xcess360 earns 3% when a lot actually closes, and nothing at all until then — so listing costs you nothing but the paste.

Someone may already be lookingThe pool knows what buyers are hunting for. If a line you are sitting on is on that list, you are not selling into silence — you are answering a question somebody has already asked.
Matched on the part, not the spellingYour list is resolved to the canonical record first, so a lot lands against every way that part gets written. Nobody misses your stock because they typed the dash differently.
Told when demand appearsNot everything sells the week you list it. Semi360 keeps watching, and tells you when someone starts looking for what you are holding.
Sami watches the pool so you don't have toAsk her what your list is worth, which lines are moving, and who has been looking for them. She reads the same pool this page does.
