How Damart scaled 15 marketplaces with AI & automation

Founded in France in 1953, Damart is a clothing brand that combines comfort, functional design and textile innovation across its collections. Its founders developed and patented Thermolactyl, the thermal textile that remains one of the brand’s signature innovations.

Part of the Damartex Group, Damart has developed an international presence across Europe through marketplaces. Innovation is embedded in its DNA and extends to the processes and technologies that support its business.

The company has worked with Lengow since 2015, progressively broadening its use of the platform. The relationship has evolved from product feed distribution to advanced catalogue management, automation and the exploration of AI use cases.

Challenges and objectives

As Damart expanded its marketplace activity across countries and channels, each new launch introduced additional requirements for managing and distributing the catalogue. This made it increasingly important to improve operational efficiency and scalability while maintaining control over catalogue quality.

To support this expansion, Damart needed to address several challenges:

• Support cross-border expansion: test new markets and develop marketplace activity without making each launch increasingly resource-intensive.
• Manage catalogue complexity: bring together non-standardised catalogue data scattered across multiple sources and adapt it to different taxonomies, languages, attributes, image requirements and publishing rules.
• Reduce manual work: limit the repetitive tasks involved in enriching, transforming and distributing catalogue data across channels.
• Maintain data quality and consistency: ensure that products meet each marketplace’s requirements while preserving reliable information across channels.
• Keep operations scalable: continue opening markets and growing marketplace activity without multiplying the operational effort required to manage them.

As Damart’s marketplace strategy accelerated, NetMarkets became central to managing and distributing product data across its marketplace network, including Amazon, Cdiscount, E.Leclerc, La Redoute, Sarenza, Zalando and Veepee. Damart also uses NetAmplify for ad feed management and custom channels for other distribution needs.

Today, Damart’s marketplace activity spans approximately 15 platforms across 9 countries, representing around 40 platform-country combinations. With NetMarkets, Damart can centralise, enrich, restructure and transform product data to meet the specific requirements of each channel and market.

Consistent with Damart’s innovation-driven approach, the collaboration with Lengow has expanded since 2026 to include AI Studio. Damart began exploring how AI could improve the efficiency of its multinational processes and optimise costs.

The following examples illustrate how Damart is applying these capabilities:

• Translation and localisation: a test covered around 1,000 products in Dutch, including titles, descriptions, colours and materials. Native speakers reviewed the content, and the initial tests achieved a level of translation quality above market standards. The approach is also expected to improve process efficiency and reduce the costs associated with external translation agencies.
• Image adaptation: Damart is rolling out automated image adaptation across several thousand products. The process resizes, compresses and reformats product images to meet each channel’s requirements, an important capability for fashion marketplaces, where image standards can be highly specific. Tests showed that products previously rejected because of image specifications were accepted after adaptation.
• Automated categorisation: Damart has also tested automatic category mapping to accelerate marketplace onboarding, notably for E.Leclerc. Initial tests produced promising results, and the use case is still being refined.

These use cases are part of a broader operating model in which Lengow helps Damart centralise, enrich and distribute product data across marketplaces and custom channels. The partnership has evolved beyond feed distribution towards a more automated approach to marketplace management.

The ecosystem in place has helped Damart absorb 25% growth over roughly three years, while keeping its internal team stable.

Looking ahead, Damart is continuing to explore new markets, marketplace channels and automation use cases to further develop its presence across Southern and Eastern Europe.
