Lemrock Raises €6M To Help Brands Sell Through AI Agents Like ChatGPT And Claude

The funding round was led by Galion.exe, with Jean-Baptiste Rudelle, founder of Criteo, joining Lemrock’s board of directors. Other participants include Michaël Benabou (Veepee), Gary Anssens (Alltricks/Decathlon), Frédéric Halley, Emmanuelle Brizay, and Antoine Lizée (Alan).

Founded in 2025 by Roxane Laigle (CEO), Sasha Collin (CPO), and Clément Nguyen (CTO), Lemrock enables brands to connect their catalogues to large language models and sell through agent-driven conversational environments. Collin and Nguyen are repeat YC S24 founders.

Lemrock’s infrastructure provides retailers with a single access point to major conversational platforms like ChatGPT, Claude, and Perplexity, handling catalogue integration, real-time availability, transactions, and performance tracking. Brands retain full control over data, margins, and presence.

Its conversational agents capture context, history, and preferences to deliver personalized product recommendations in real-time, surpassing traditional e-commerce search capabilities.

Lemrock operates a complete middleware stack that connects product catalogues, AI agents, and transactions through a single integration point. Recently, the company was selected to join Agoranov, one of Europe’s leading deeptech incubators. Its infrastructure is built on proprietary AI models, trained on the largest independent agentic commerce dataset outside Big Tech.

Lemrock has partnered with over 60 active brands across Europe and the US, including Maisons du Monde, Cdiscount, Darty, DIM, Engie, and Lebara, managing more than 100 million interactions monthly.

“Connecting catalogues, exposing prices and availability in real time, enabling transactions, monitoring performance… All of this requires a complex technical stack that internal teams neither have the time, expertise, nor resources to build. This is precisely what we solve with Lemrock,” explained Roxane Laigle, CEO of Lemrock.
