SaaS + Marketplace

The hybrid business model that pairs a software-as-a-service product with a transaction marketplace — using SaaS to acquire and retain one side of a market, then layering a marketplace on top to monetize transactions between the two sides. In Kyle’s reading capture this is anchored to Casey Winters’ essay “The SaaS + Marketplace Model,” saved on June 18, 2026 and cross-tagged to Marketplaces and B2B Marketplaces. The page is a saved-for-later reading thread rather than a synthesized analysis — the three sibling stubs (Marketplaces, B2B Marketplaces, and this one) all point at the same Casey Winters source.

Context: The “SaaS + marketplace” pattern — articulated by operators like Casey Winters and a16z — describes companies that lead with a software tool to lock in supply or demand (giving a side a reason to show up daily), then add a marketplace layer to capture transaction revenue. Examples often cited include OpenTable, Shopify, and various vertical B2B platforms. The SaaS side reduces the marketplace’s cold-start and disintermediation problems.
