# Retter

> Retter designs, builds, integrates and operates enterprise platforms: commerce, loyalty, backoffice, integrations and cloud infrastructure, with AI put to work inside them. We replace legacy platforms for brands such as Starbucks, A101, CarrefourSA and Costa Coffee, connect them to the systems the business already runs, and stay responsible for operating and improving them. Our work spans retail, grocery, food service, airports and insurance across Türkiye and the Gulf.

Backend engineering is Retter’s core strength: replacing legacy commerce and loyalty platforms (SAP Hybris, Oracle Commerce Cloud, closed SaaS vendors) on AWS serverless, integrating banks, airlines, stores and delivery partners, and operating the result with the same engineering team after launch.
Customers include Starbucks, Gratis, CarrefourSA, A101, MMI, PAUL (Azadea Group), Costa Coffee, Pret A Manger, Shake Shack, Spinneys Abu Dhabi, Emirates Leisure Retail, istegelsin, Lululemon, Unifree, İstanbul Sabiha Gökçen Airport and Medisa Sigorta.
A detailed specification is not required to start: scope, integrations and launch requirements are agreed with the customer, with experienced people handling architecture, validation, compliance and ongoing operation.
Build across business domains. Grocery, retail, F&B, loyalty and commerce show areas of deep experience, not the limits of the offering.
Customer evidence: each published case study describes a specific engagement. Historical platform results are not forecasts for new projects or measured AI performance.
