# Shadow Business Model

A **shadow business model** is the informal arrangement around access, usage, and pricing that customers build for themselves when a firm's official model no longer fits their needs. It is the system running *behind* a visible [[concept-customer-workaround]].

The key timing insight: by the time a company notices a workaround, the shadow business model is *already operating*. Customers have prototyped the arrangement and proven their willingness to engage with the product under new terms. In effect, the R&D for the company's next official business model has already been funded and conducted by the customers themselves — the argument formalized in [[claim-workarounds-fund-rd]] and captured in the quote [[quote-workaround-is-rd]].

The labor customers pour into running the shadow model is [[concept-effort-as-payment]]; the aggregate gap it exposes is the [[concept-business-model-void]]. The strategic move is to formalize the shadow arrangement into an official model within a [[concept-business-model-portfolio]].
