Upgrading the resale experience by helping sellers and buyers connect faster


Maximizing simplicity in second-hand sales process

Gebraucht.de came up with an idea to offer customers a better way to sell used goods. We worked with Gebraucht to help the company build an m-commerce shopping application.

Gebraucht was created by Stefan and Olivier, who wanted to streamline how customers sold and bought used, refurbished, and vintage items.

The team at Gebraucht spotted inefficiencies in the selling and buying process of used goods via classified ads. The process lacked automation and was cumbersome.

Paper-based ads or online ads often require people to exchange goods personally. On top of that, the communication lacks transparency, and the payment is anything but secure and convenient.

An m-commerce app is a great way to modernize the traditional selling process of used goods. With a mobile application that improves communication and simplifies transactions, Gebraucht could reach a larger pool of users interested either in selling or buying used merchandise.

Scope of Work

We developed a cross-platform m-commerce app with streamlined selling processes, secure payment options, and advanced search functionality to enhance the buying and selling experience for used goods.

App Development for iOS and Android

Utilizing Swift and Kotlin technologies to create a user-friendly m-commerce application for both iOS and Android platforms, focused on facilitating the sale and purchase of used, vintage, and refurbished items.

Intuitive Selling Interface and Payment System

Designing an easy-to-use interface for users to list products for sale and integrate a secure, convenient payment module for transactions within the app.

Advanced Search and Filtering Features

Implementing sophisticated search capabilities and advanced filters that let users efficiently locate specific products within the app's marketplace.


We went from developers to active idea-suggesting partners in this project. The think tank we created with the co-founders helped us design and develop functionalities that went beyond the project’s initial assumptions. These functionalities had a direct impact on the success of the app — Gebraucht.de generated 15k+ users during the first 30 days after launch.

A user-focused m-commerce app available on iOS and Android. With Gebraucht.de, users can buy and sell used, vintage, and refurbished goods via a simple and efficient UI. The app features a secure payment solution and offers unique shipping options. In-app tips help users find and sell their products faster.

"Their energy in making the most of your product’s value is unmatched."
