Marketplace
A multi-vendor e-commerce platform where third-party sellers list products alongside (or instead of) a first-party catalogue. Amazon, Etsy and eBay are the canonical examples.

A marketplace is an e-commerce platform that hosts multiple sellers under one storefront. The marketplace operator handles discovery, search, payments and trust; sellers list inventory, set prices and fulfil orders. Revenue typically comes from take-rate on transactions, listing fees, advertising or some mix. Amazon, Etsy, eBay and Faire are the well-known shapes.
For brands, marketplaces are a reach play. You're trading margin for traffic you couldn't otherwise buy, in a venue where shoppers arrive with intent. The trade-off is platform risk (rule changes, algorithm shifts, account suspensions), commoditisation pressure and loss of customer relationship data. Smart brands run marketplaces as one channel among DTC and retail, not as the whole business.
For operators building a marketplace, the engineering is its own discipline. Vendor onboarding and KYC, split payments and payout schedules (Stripe Connect, Adyen for Platforms), trust and safety, ratings, dispute handling, search ranking, and the fundamental two-sided cold-start problem. A marketplace is two products — buyer and seller — built simultaneously.
Devinsta builds marketplaces on Stripe Connect, custom React/Next.js front-ends and headless commerce engines, and helps brands integrate marketplace channels into their core commerce stack without losing operational control.
