## About this market
Milan's B2B bench is engineering-led with academic ties, and the published work divides neatly between firms that report a number and one that reports an architecture. Xtream's hourly power-load forecasting cut relative error by 24 percent on residential and 26 percent on industrial demand and became the utility's official tool, with a food-and-beverage demand model retrained monthly beside it. Buildo's Banksealer fraud ranking, developed with Politecnico di Milano and reimplemented in Scala, runs on-premise without an internet connection at 200 transactions a second. Algoretico publishes the architecture instead: multimodal search over text, images, drawings and CAD for the packaging manufacturer ILPRA, built on CLIP and Flamingo with retrieval-augmented generation on top.

Both kinds of evidence are worth something, and they answer different questions. An architecture write-up tells you a team can design; a production number tells you the design survived contact with an operation. For a B2B buyer the second is the harder thing to obtain, so ask for it directly: which model is in production today, what did the error rate do, and who retrains it. Ask too where the work runs, because two of the systems on this page were deliberately built for environments with no outbound connection.

### How is B2B experience verified on this page?
