# Stack

> Ask your data anything. Get evidence back. Stack interrogates your data, forms hypotheses, tests them with real statistics and turns what survives into an evidenced PowerPoint.

Stack is a Linear Horizon product. It connects read-only to an organisation's data sources, profiles the data, runs deterministic statistics, generates hypotheses for an open-ended question, tests each one, and marks it supported, weakly supported, rejected or inconclusive. Surviving findings become an evidenced presentation. Raw rows are not sent to the language model. Customers' own teams run their investigations. Start by requesting a demo. HTML pages are canonical.
