Success stories

Challenge

Complete overhaul of a community platform dedicated to reading enthusiasts. Book Village had been stuck at 10,000 users for over two years.

Solution

Enhance all the features and improve UI/UX. SEO optimization

Result

Reading is an essential element of our lives. Whether past or present, the culture of reading has never lost its importance. The "Book Village" was born from the ambition to create a reading space for sharing and accumulating knowledge for all. MORE THAN 150,000 USERS PER MONTH Thanks to our intervention, their growth is estimated at 300,000 users in three years, and their SEO has skyrocketed with a 700% increase. We managed the entire overhaul, from UX/UI to SEO optimization.

Challenge

ARNTREAL is an innovative fashion brand that combines clothing with interactive gaming experiences. Founded by Andrea Albrizio, the company offers clothing with unique NFC chips, allowing users to connect their outfits to a dedicated mobile app.

Solution

App development, Design UI/UX. Concept is connected clothing integrating NFC chips, offering a unique interactive experience.

Result

ARNTREAL participated in the show "Qui veut être mon associé?" (Who Wants to Be My Partner?) broadcast on March 5, 2025, on M6. During the show, Andrea Albrizio shared his personal journey, including the challenges he faced from bullying, and how this inspired him to create a "magical" clothing brand. Participation in the show significantly boosted brand visibility, generating over €300,000 in sales in just 2 hours even before the episode aired.

Challenge

LIVMED'S is a 24/7 medicine and parapharmacy delivery service built around a 30-minute fulfilment target. Digital Unicorn designed and developed the complete ecosystem from scratch: a consumer app, a pharmacist-facing merchant app and a web platform.

Solution

Because the product handles medication rather than ordinary retail, the ordering flow was designed around prescription validation and pharmacist confirmation instead of a standard e-commerce checkout. Delivery is matched geographically to the nearest participating pharmacy.

Result

The build covers geolocated pharmacy matching, real-time order tracking over Socket.IO, secure payment and an in-app wallet, a loyalty scheme and a rating system, plus the merchant-side stock and order management tools. Stack: React Native, React.js, Node.js and Redux, shipping on iOS, Android and web. LIVMED'S has since passed 100,000 users and raised over 10 million euros.

I stepped into Digital Unicorn feeling super cautious, but they quickly cleared every doubt. We had weekly chats, and each one left me pumped. I definitely saw my app turn from a rough draft to something smooth Their easygoing approach kept me going, and I'd do it all over again if I had to.

We worked with Digital Unicorn on the development of our web platform. They listened carefully to our needs, created excellent mockups, and delivered in sprints as planned. Their process and methodology are truly enjoyable. The team is very knowledgeable about web and mobile development. Whether it's Lucas, Sébastien, or Martin, thank you again to them. We're continuing to work with them on maintenance.

I'm Gilles Fonseca, founder of the Captain-Fisher app, which is basically a platform for fishing and boat rentals. I wanted to leave a review to express my gratitude to Digital Unicorn, a company recommended to me by a business angel who had worked on the app and was very satisfied with their work. After working with two development companies, I struggled to find competent people, especially in a constantly evolving field. Now, I've been working with Lucas's team for over a year and a half, and I'm 100% satisfied. Digital Unicorn rebuilt both the front-end and back-end of the app for iOS and Android, and this year they redesigned the website/app for PC. I also recommend them because their rates are more than competitive and, above all, high-quality. The team and management are available and attentive, and their responses to changes and other issues are quick. Don't hesitate to contact them, I'm sure they'll help you achieve your project. Happy to work with Digital Unicorn.
