Velvet House offers the rarest kind of luxury: deep disconnection, in beautiful and unusual homes, nestled in nature—just under two hours from the city. With a bold ambition to become the go-to name for unique getaways, Velvet House needed more than just a brand. They needed a universe—instantly recognizable, wildly desirable, and frictionless from first click to booking. Together, we built the foundation: from early research and strategy to the complete UX/UI and tone of voice. The result? A digital experience designed to inspire, convert, and earn trust—across all types of travelers.

Our mission: make the Joko experience even easier, smarter, and more affordable for every user. Through workshops, one-on-one sessions, and deep product thinking, we helped Xavier and his team structure the future of Joko — turning their ambitious vision into clear product foundations and actionable wireframes.

Sophie d’Agon is a jewelry infused with color, emotion, and timeless elegance — a Parisian brand celebrated for its delicate designs and joyful spirit. When her team approached us, their collections were already beloved by a growing community, but their brand identity and digital presence no longer reflected the uniqueness of their creations. Our mission: to rethink the entire brand platform, from the visual identity to the online experience, and give Sophie d’Agon a fresh, modern look that would capture the emotion behind every jewel — and support the brand’s next phase of growth.

PhantomBuster is a game-changing sales automation platform used daily by startup growth experts worldwide. It helps teams identify ideal prospects, enrich contact data with real-time insights, and engage them across multiple channels—faster and more effectively than ever. With the rapid rise of AI, the landscape surrounding PhantomBuster is evolving at an unprecedented pace. Recognizing the need for swift action, Guillaume sought a partner who could bring fresh perspectives and limitless creativity to the table, helping to navigate this transformative journey. Our journey with the PhantomBuster team began in 2017 in San Francisco, where we met Guillaume and Martin while participating in The Refiners accelerator program. We shared experiences and built strong connections between Parisoma and Joost Avenue. This mission was particularly special as it was a collaborative effort between Emmanuel (Founder at Sigmoon) and Guillaume (CEO of Phantombuster) to shape the future of Phantombuster.

When the ESSEC Business School launched their deeptech studio Momentum, they set out on an ambitious mission: to turn world-changing technologies into viable, scalable startups that can reshape our future. But before they could attract entrepreneurs, investors, and scientists, they needed something essential — a clear, bold identity that would match their purpose. That’s where we came in. We partnered with Momentum to create their very first brand, from strategy to execution. Together, we transformed their vision into a strong, modern, and meaningful identity that could speak to the deeptech ecosystem and the academic world at once.

Klark's mission is to transform the way companies engage with their customers through generative AI technology, building the future of customer care — where generative AI doesn’t replace humans, but gives them superpowers. From the very beginning, the founders knew they needed more than a smart product: they needed a sharp, confident brand to match their ambition. We teamed up with Klark from day one to shape their strategic foundation, define their voice, and build a visual identity that feels as intelligent as their tech — but also warm, simple, and deeply human. From logo design and UX writing, every piece of the brand was crafted to reflect their core belief: AI is at its best when it works hand-in-hand with people.

Sunity is a plug-and-play solar panel kit that lets you generate your own electricity—no complex installation, no technical expertise required. Just plug it into a standard outlet and start producing energy instantly. Breaking into the fast-growing solar market isn’t just about technology—it’s about standing out in a crowded, sometimes mistrusted space. Sunity needed to cut through the noise with a bold, distinctive brand that would instantly convey trust, simplicity, and innovation. We partnered with Sunity to craft a brand that feels professional, accessible, and joyful. A playful sun mascot embodies the ease of the solution, making solar energy less intimidating and more intuitive. At the same time, the visual identity asserts Sunity as a credible, future-forward player in the energy transition. Our mission: Make solar effortless, trustworthy, and truly for everyone.

 At Sigmoon, our mission was to build a strong brand that resonates with businesses of all sizes, from dynamic startups to established corporations.

Our approach focused on showcasing diverse use cases to maximize understanding and implementation.

38.2 came to us with a bold mission: to revolutionize the image of medical practices. They didn’t want to follow the well-worn path of sterile, conservative healthcare branding. Instead, they envisioned something different—an identity that would feel fresh, youthful, and forward-thinking, while still grounded in professionalism and trust. But unlike most healthcare brands, this one wasn’t built with patients in mind. The entire branding was designed to speak to doctors—and only doctors. 38.2’s priority was clear: attract a new generation of medical professionals by offering a radically better work environment, and a strong, inspiring brand to match. Before they could change the way care is delivered, they needed to build the team that would deliver it. The challenge was clear: how do you inspire trust and confidence while daring to innovate in a highly sensitive sector? That’s where we came in.
