- Your ROI multiple4.0×
Calculator uses your live inputs. Contract enforces this math word-for-word. Backed by a 14-day shadow-mode replay if any savings are disputed.
We don't just show the spike — we point to the line.
Every other FinOps tool tells you "you spent $10k on tokens." CARTIE tells you "you spent $10k because of line 42 in stream.py" — and writes the fix as a PR.
