A formula behind the number, disclosed end to end
Larridin's Agent Effectiveness grades live sessions from Claude Code, Codex, Cursor, and Cline, and its enterprise Spend Intelligence tracks token and licence spend, real capability behind a reported $2.4M in median AI spend optimized. Tetriz's AI ROI is a disclosed formula instead: cycle-time savings per merged PR, valued at loaded engineering cost, minus the AI Tax and total AI spend, and it flags recoverable spend, sessions that went nowhere, with coaching or seat right-sizing to act on.
