Same-day delivery between stores, launched in 6 months
Decathlon, the largest sporting goods retailer in the world, needed an app that lets staff find a product in another local store and bring it in within hours.

The challenge
Small stores, lost sales
Decathlon’s concept stores in Warsaw had little floor space, so customers often could not find what they wanted and left. The company wanted to launch same-day delivery: staff check availability in other local stores and bring the product in within hours.
Time and budget were strictly limited.
What we did
The simplest architecture that does the job
We worked with the client’s team in workshops to design the shipment process and the features it needed. To meet the time and budget, we recommended a Progressive Web App: faster to build than native apps and usable on any device, from the browser or installed on iOS and Android.
The project ran in two-week sprints with a demo after each one.
The result
Live in 6 months, +30% sales volume
After 6 months the stores launched same-day delivery. The app stopped the loss of customers, opened a new revenue stream and increased sales volume by 30%. A simple process in the app saves sales assistants time every day.
Technology
“Appstronauts used Agile methodology, and the whole work was divided into sprints. We could track the progress in Jira, and after each sprint, new features were presented to us during a demo.”
