Atrium AI - AI Agents for Hotel Procurement

Hey Product Hunt 👋 I spent about a decade running operations in hotels before I ever wrote a line of code. And the thing that always got me was how much money leaked out through invoices nobody had time to check. A case gets billed at $8.40 when the contract says $7.10. A volume discount you earned never shows up. A fuel surcharge appears out of nowhere and nobody remembers agreeing to it. None of it is dramatic. It is a few dollars here, a line item there, and it adds up to thousands a year per property, quietly, before anyone notices. Enterprise hotels have whole teams and expensive software for this. Independent hotels have a busy GM, a stack of PDFs, and no time. That gap is why I built Atrium. Atrium compares what was ordered, what arrived, and what was invoiced, then flags what needs review before you pay the supplier. It reads your contracts too, so every invoice gets checked against the deal you actually signed. The build itself evolved a lot. It started as something much broader and honestly too ambitious. Talking to operators pulled me back to the one thing they all felt but nobody was solving: catch the problem before the money leaves, not after month-end. Would love your feedback, especially if you have ever run purchasing for a hotel, restaurant, or any business drowning in supplier invoices. What would you want it to catch first?
