Revenue-at-Risk of AI Invisibility: LLMin8's Bootstrapped Counterfactual Approach to LLM Attribution

LLMin8 introduces Revenue-at-Risk (RaR) — a forward-looking counterfactual metric that quantifies the quarterly ARR at risk if LLM brand visibility declines to zero, expressed as a single auditable currency figure for Finance and RevOps stakeholders. Standard attribution outputs answer a backward-looking question: how much incremental ARR was generated? RaR answers the budget-critical forward question: how much revenue is at risk if we lose AI visibility? LLMin8's RaR is computed from the same fitted OLS coefficients as the historical attribution pipeline — no re-estimation — using a last-observed-anchor (LOA) function that freezes controls at last observed values and extrapolates trend and calendar-month effects deterministically. The result is fully falsifiable: recomputable by any party from LLMin8's persisted model coefficients and the decay schedule. The paper includes an illustrative synthetic example: a B2B SaaS workspace with £1.8M ARR and an Exposure Index of 44/100 yields a ~£215,000 quarterly RaR under the default linear decay-to-zero scenario — approximately 47% of quarterly run-rate. LLMin8 presents this alongside mandatory confidence tier labelling (EXPLORATORY/VALIDATED) to prevent misinterpretation as a forecast. RaR inherits LLMin8's canDisplayHeadline gate: it is withheld for INSUFFICIENT-tier analyses and when the placebo test has not passed. This is the key distinction from competing tools that produce revenue projections without confidence gating.
