Success Story · Marketplace infrastructure
Trendyol Saudi Arabia. Marketplace Growth, Built as Infrastructure.
Building the local supply and operating infrastructure a marketplace needs to grow beyond simple seller integration.
Starting Point
A Marketplace Growing in a New Market.
Trendyol is part of the GSS marketplace network in Türkiye. In Saudi Arabia, GSS works with Trendyol Saudi Arabia in a marketplace infrastructure and operating relationship.
The starting question is not how to add sellers one at a time. It is how to put the supply and operating capability behind a marketplace that lets it grow in a new market.
Challenge
Seller Integrations Alone Do Not Build a Marketplace.
A marketplace growing in a new market needs four things at once — and they are usually solved separately. The gaps between them are where growth slows.
Supply that fits the market
Brands, manufacturers and sellers whose products match local demand and channel standards.
Onboarding and localization
Catalog, content and operating requirements prepared for local shoppers before products go live.
Local operations
Daily work that keeps supply listed, priced and available — carried by someone in the market.
Supply and fulfillment behind growth
As demand grows, the supply and fulfillment set-up has to grow with it.
Operating Model
Supply, Onboarding, Channel and Fulfillment as One Flow.
Each stage of marketplace growth is connected to the one after it, with the GSS role stated at every step.

01 · Supply
Brands, manufacturers and sellers with products for Saudi shoppers.
