In February 2022, we began our collaboration with Alexandre Roubaud and Kabir Sethi, co-founders of Bitstack. Our goal was to design an intuitive product and a strong brand to democratize Bitcoin in France and Europe. We had the opportunity to design the product, the website and the brand.

In just two years, we have achieved highly ambitious goals through strong team cohesion, a sound strategy, and a consistent focus on deliverability. Every day, we strive to produce our best proposals to serve our users and grow the product.

La marque

A modern artistic direction was developed, accompanied by approximately 50 illustrations that reinforce and enhance the overall concept. This work has significantly strengthened the brand's influence in our market, providing a valuable competitive advantage. This project illustrates the importance of a strong visual identity to stand out and make a lasting impression in a competitive environment.

We designed a series of versatile and cohesive visuals to meet all of Bitstack's communication needs. These visuals were adapted for social media, ensuring a strong and recognizable identity across all platforms. Additionally, we created professional email templates that reinforce the brand image in interactions with users and partners.

A carefully crafted icon pack has been designed to visually embody Bitstack's core values and mission. Each icon has been thoughtfully created to convey the brand's essence, highlighting its commitment to innovation, simplicity, and accessibility.

This work contributes to strengthening Bitstack's visual identity while offering graphic consistency across all communication media.

Le produit: Application mobile

In just two years, the Bitstack application has evolved into a comprehensive and sophisticated product, incorporating around thirty features and hundreds of meticulously designed screens. Each feature has been thoughtfully conceptualized and designed in close collaboration with engineering teams, ensuring perfect synergy between visual aspects, user experience, and technical constraints. We have made it a priority to simplify processes often perceived as complex, making the application accessible to everyone, from novices to seasoned users.

This user-centered approach has resulted in an intuitive, seamless, and frictionless experience. Positive feedback from our users confirms the success of this approach: they praise not only the ease of navigation but also the added value the application brings to their daily lives.

Over the past three years, we have developed a robust and structured design system comprising over 300 components. This system enables us to efficiently manage more than 1,000 screens across 30 different flows.

By adopting this modular and scalable approach, we ensure visual and functional consistency on a large scale, while significantly reducing design and development timelines. This system has been essential in supporting product growth, facilitating collaboration between development and design teams, and maintaining a high level of quality in every user interaction.

Le site internet

We designed a comprehensive 30-page website to provide an optimal user experience and showcase Bitstack's innovative approach to Bitcoin savings. This site was crafted to combine clarity, aesthetics, and efficiency, guiding users at every step and reflecting Bitstack's excellence in its field. The Bitstack website is ranked in the top result on the keyword: Bitcoin (for french result).

Bitstack has an ambitious vision with many exciting projects underway to establish Bitcoin as a cornerstone of modern finance. Among these initiatives, the Bitstack Card aims to revolutionize spending habits by offering Bitcoin cashback on every transaction, turning everyday expenses into investment opportunities. This is just the beginning.

We are proud to support Bitstack in this journey, bringing our design expertise to foster their growth and help them reach new heights. Each step of this partnership brings us closer to a future where finance is more open, accessible, and aligned with user needs. Our enthusiasm for contributing to such a significant transformation continues to grow.
