Case Study: Istegelsin (Turkish online supermarket) achieves 35%+ ROAS lift and accurate cross-platform attribution with Adjust

Unboxed Agency boosts Istegelsin's ROAS over 35% with Adjust

Istegelsin is a Turkish online supermarket founded in 2018 that aims to scale user acquisition and retention in a competitive, digital-first market. Working with Unboxed Agency, the marketing team struggled with fragmented measurement across multiple ad platforms and time-consuming SDK setups, which led to attribution duplication of up to nearly 50% and limited ability to compare KPIs (first-time buyers, LTV, CPA, CVR) or make real-time optimization decisions.

They implemented Adjust for a single, automated attribution model with straightforward SDK integration, Raw Data Export, Audience Builder and an advanced Fraud Prevention Suite. This gave a unified dashboard and real-time visibility into over 200M monthly events, eliminated duplicate attribution, enabled granular budget allocation and campaign optimization, and improved ROAS by more than 35% while allowing the team to pause questionable sources within hours.
