LastBuy

When a supplier discontinues a part, they send a letter with a part number and a last-buy date. The hard part is working out what that letter breaks. One chip can sit inside three assemblies and five products. Today someone works that out by hand, in spreadsheets, before the date runs out. After it, the part is gone for good. LastBuy does that work. You give it two things: the letter (a PDF, a scan or a photo, in any language) and your bill of materials as a CSV. It reads the letter, finds your parts, walks the bill of materials up to every finished product, and tells you how many to buy, what that costs, and how much revenue it protects. In our example, one Analog Devices isolator stops 5 products with €9.06M a year of revenue behind them. LastBuy says buy 504,798 units (€1.43M) within 34 days. How it works: - MinerU2.5-Pro on AMD Instinct reads the letter. A notice is a form, so we read the ticked box and labelled date first, and only ask a model for what the page doesn't say. - Gemma-4-31B-IT on AMD writes the memo and powers Vigil, the assistant on every page. Every answer cites its source. - An Evolus agent in our workspace "lychee" rules on certificates and cites the clause. - The impact engine is plain code. Every number you act on is arithmetic you can check, never a model's guess. A full assessment costs about a hundredth of a cent, so you can read every notice, not only the ones that look important.
