Marketplace economics are the inverse of SaaS: revenue is a thin slice of a much larger gross merchandise value (GMV), and the long-run value of the business hinges on whether the platform achieves liquidity — enough buyers and sellers transacting frequently enough that neither side defects to alternatives.
A marketplace valued purely on EV/Revenue understates the network value embedded in transaction volume and the cohort liquidity curves. We model GMV, take-rate (gross and net of incentives), contribution margin by category, and cohort-level repeat behaviour. The DCF projects all four, then triangulates against EV/GMV and EV/Net-Revenue comparables.
UK marketplace comparables are scarce — most public listings are US-based. We adjust for currency, regulatory environment, and category-mix differences when reading across to UK businesses. IVSC IVS 105 expects this triangulation to be explicit; HMRC SVM expects the take-rate assumption to be benchmarked against precedent transactions.
