Connecting fans and celebrities

Challenge: building a high-performance e-commerce platform for digital products

Hamburg-based start-up wewave offers something truly special for family, friends, and business partners: personalised video messages from celebrities that support a good cause. Customers can book everything from a quick greeting from European champion Hansi Müller for a football-mad dad to birthday wishes from Bergdoktor star Ronja Forcher for a sister-in-law. A portion of the proceeds from each wave goes to a charity chosen by the stars themselves, which they communicate transparently on their wewave profile.

Approach: The Perfect Interplay Between Website and App

We have been supporting the start-up from the very beginning. In just under three months, an agile team of developers, designers, and UX architects built the wewave platform. At its heart is the website, through which both private individuals and companies can book their video messages. Celebrities can respond to incoming requests using the Creator App, where they create waves and make them available to customers directly through the app.

Solution: Shop System and App Development with Refined UX Design

UX design was consistently at the heart of the implementation: the Creator App offers extensive personalisation features and an exceptionally simple and fast way to handle video requests. The website is built on the proven e-commerce shop system Shopify, which our team adapted to the wewave process to make the booking flow as simple and individual as possible.

Built on Shopify

By customising the shop system, the young company ensures the best possible booking experience. The e-commerce platform allows customers to submit personalised video requests, where they can express their wishes to celebrities and their waves. Once the video is ready, customers can access, download, and share it. The shop's responsive design guarantees seamless access from any device.

App Development in Focus: Creator App

In addition to the flexible customisation of the Shopify shop system, app development is the second key pillar of the project. With the Creator App, celebrities can use a single tool to respond to video requests, create waves, edit their profile information, and get an overview of incoming and completed bookings. Thanks to precise UX design, the experience is uncomplicated and easy to understand — making the recording of waves genuinely enjoyable.

Scalable System Architecture: The Technical Foundation for a First-Class User Experience

To ensure a constant exchange between the shop system and the Creator App, we developed a highly flexible and scalable system architecture. The wewave Connector acts as the hub of the architecture, enabling seamless data exchange between the shop and the Creator App.

The wewave Connector is a cloud-based system that acts as a bridge between the e-commerce platform and the Creator App. It will also allow us in the future to seamlessly connect additional apps — such as for private customers — to the shop system. This means the wewave platform can be expanded flexibly, in line with the needs of the growing company.
