WaterfallBridge — Explain Any KPI Change

Ask in plain English why a metric moved. Get an auditable, reconcilable breakdown — not a hallucinated guess.

WaterfallBridge pairs a deterministic variance-bridge algorithm with an LLM:

• —🧮 Algorithm does the math. A waterfall / variance-bridge decomposition splits any change in a value, % or rate KPI (revenue, gross margin %, conversion, retention, yield…) into its drivers, by dimension (product, region, channel, segment, campaign…). Every number is reconcilable — the drivers add back up to the total change.
• —🤖 AI does the talking. The model turns your natural-language question into the right analysis and explains the result in words. It never invents the numbers — they all come from the algorithm, so the explanation is grounded and verifiable.
• —🔌 Agent-ready. The same engine is callable by AI agents through the Model Context Protocol (MCP).
