BLNG is a French fashion-tech startup applying generative AI to one of the most craft-intensive corners of design: luxury jewelry. Creating, visualizing, and marketing fine jewelry traditionally involves slow CAD modeling, costly physical prototypes, and expensive photoshoots, all of which limit how quickly designers can iterate and how richly brands can present their pieces. BLNG compresses that process by transforming sketches into photorealistic designs and even animated renderings in seconds, giving jewelers a faster, more flexible creative and commercial toolkit.
The company organizes its technology around three integrated solutions. BLNG Design enables instant design visualization, letting creators explore variations of a piece without manual rendering. BLNG Studio generates high-fidelity marketing content, removing the need for costly product photoshoots. And BLNG Retail powers personalized customer experiences with real-time customization, helping brands drive conversion through interactive visualization at the point of sale. Together these address the full jewelry value chain from concept through marketing to retail.
BLNG was co-founded by Valérie Leblond, who previously directed UCLA's IDEAS research platform, and Dumëne Comploi, who holds ten engineering patents and worked at Walt Disney Imagineering and Disney Streaming. In April 2025, the company raised $3 million in seed funding led by Speedinvest, with participation from Cove Fund, eSeed, and Focal. BLNG has also earned notable recognition, including an LVMH Innovation Award for the most promising data and AI solution at Viva Technology and a place on Vogue Business's 100 Innovators list.
By focusing tightly on jewelry rather than apparel or general imagery, BLNG brings domain-specific realism to materials like gemstones and precious metals that generic image tools handle poorly. Its combination of design, marketing, and retail tools, strong founding pedigree, and luxury industry validation positions it as a specialized leader in AI-driven jewelry creation.
