Lemrock Secures €6M to Power AI Agents for Commerce

A seismic shift is underway in how consumers discover and purchase products, moving from traditional search engines and websites directly into conversations with AI. Paris-based startup Lemrock has secured €6 million in funding to build the essential infrastructure for this new era of conversational commerce, ensuring brands can effectively sell within AI platforms like ChatGPT and Claude. The investment round was spearheaded by Galion.exe and supported by a group of prominent retail and tech angels, signaling strong belief in the company’s vision.

The core problem Lemrock addresses is both urgent and structural. As shoppers increasingly ask AI assistants for product recommendations, brands face a critical disconnect. There is no reliable system to ensure their products appear accurately, with correct pricing and availability, or that a transaction can be completed seamlessly. Lemrock positions itself as the vital middleware, a single integration point that connects a retailer’s product catalog to major AI platforms. This system manages real-time data, processes transactions, and tracks performance while letting brands retain full control over their data and how products are presented.

The urgency for such a solution is underscored by significant traffic declines some retailers are already reporting. According to Lemrock, certain brands are seeing drops of up to 30% as consumer behavior migrates from Google searches to AI agent queries. This trend fundamentally reverses the traditional commerce model. The customer is no longer coming to the brand; the brand must now be present and instantly transactable wherever the customer’s conversation is happening.

“The old logic of the customer searching for a product is fading,” explains Roxane Laigle, Lemrock’s CEO. “Conversational commerce means the right product finds the right customer. Our technology empowers brands to sell more effectively and allows consumers to buy better, faster, and with far less friction.”

The founding team brings a potent mix of expertise directly relevant to the challenge. CEO Roxane Laigle contributes over a decade of B2C growth and retail experience from her background at Fnac Darty. She is joined by CPO Sasha Collin and CTO Clément Nguyen, both repeat Y Combinator founders from the S24 batch. Collin’s experience includes three years at McKinsey’s AI division, QuantumBlack, while Nguyen has a strong background in adtech and retailtech from Rakuten Advertising. The company, legally registered as Lemrock AI SAS, was incorporated in late 2025 and is based near Paris.

Adding to its credibility, Lemrock has been selected for Agoranov, a leading European deeptech incubator, providing further institutional validation for the team’s approach. A notable addition to the cap table is Jean-Baptiste Rudelle, co-founder of the adtech giant Criteo. Rudelle not only invested through his role on Galion.exe’s investment committee but will also join Lemrock’s board of directors, bringing invaluable scale-up experience.

The market Lemrock is entering is nascent but quickly attracting attention. Other players, like Perplexity with its own commerce features and startups such as New Era of Shopping, are exploring similar territory. Lemrock differentiates itself by pitching a vendor-neutral middleware layer rather than a competing storefront. Its value proposition is one streamlined integration that works across multiple AI platforms, designed from the ground up to be brand-safe and give retailers control in a fragmented new landscape.
