ChatGPT explains. XimTier proves.
LLMs, regression and generic ML answer only part of a decision. XimTier solves the math of 'how much to change to hit the target.'
- Not a tool you prompt.
- Not a regression report.
- Not a black-box model.
- It's a decision engine, with the math attached.

Two enemies we fight
Enemy #1 — Gut feel and spreadsheets
Senior-analyst intuition, manual Excel work, and BI dashboards that only show retrospective analysis. None can answer 'how much to move to hit the target?'
Enemy #2 — LLM hallucination
ChatGPT/Claude *generate* plausible explanations but not data-grounded mathematical *proof*. They cannot survive an audit.
Why this matters
Reverse What-If
Beyond regression — reverse-solve each variable's optimum to hit a target in 0.18 seconds.
SHAP auto-attached
Every decision ships with per-variable contribution and mathematical justification. EU AI Act Article 13/14 evidence pack.
100% on-prem
Zero external LLM calls. Passes finance, defense, and medical security policy as-is. Sovereign AI operation.
Three regs at once
EU AI Act + Korea AI Framework + KR MFDS medical-device guidance — one auto-generated document set.
