Paris-based Lemrock raises €6 million to help brands sell within AI agents like ChatGPT and Claude. March 11, 2026 Lemrock, a Paris-based DeepTech startup building the infrastructure for agentic commerce, today announced a €6 million ($7 million) funding round to accelerate the deployment of its agentic commerce solution. The round was led by Galion.exe, an early-stage VC fund. Jean-Baptiste Rudelle, the founder of Criteo and a member of the fund's investment committee, also joins Lemrock's board of directors. The round additionally includes other notable investors from the tech and retail sectors, such as Michaël Benabou (Veepee), Gary Anssens (Alltricks / Decathlon), Frédéric Halley (retail tech investor), Emmanuelle Brizay (tech and retail investor), and Antoine Lizée (Alan). "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. According to the company, internet users are increasingly relying on conversational AI agents such as ChatGPT, Gemini, or Perplexity to gather information, compare products, and make purchasing decisions. Lemrock notes that these new behaviours are significantly altering access to content, services, and e-commerce platforms. Consequently, some organisations are experiencing up to a 30% decline in website traffic. However, retailers are not yet prepared to be visible and effective on these new channels. The French startup believes that the essential infrastructure simply does not exist. It warns that brands that aren't visible, understood, and transaction-ready inside these new channels risk losing both distribution and customer relationships. Founded in 2025 by Roxane Laigle (CEO), Sasha Collin (CPO), and Clément Nguyen (CTO), Lemrock enables brands to connect their catalogue to large language models and sell directly through agent-driven conversational environments. Collin and Nguyen are both repeat YC founders (YC S24). Its infrastructure offers retailers a single access point to major conversational platforms (ChatGPT, Claude, Perplexity, etc.): catalogue integration, real-time availability, transaction handling, and performance tracking. Brands maintain full control over their presence, data, and margins, stated the startup. Unlike traditional e-commerce, conversational agents not only answer questions but also gather context, history, and user preferences during the conversation. Lemrock uses this extensive information to improve product recommendations in real-time, achieving a level of detail that traditional search engines cannot. "Conversational commerce reverses the logic: it's no longer the customer searching for the product; it's the right product coming to the right customer, tailored to their needs. Our technology allows brands to sell better, and consumers to buy better, faster, more fairly, and with less friction," adds Laigle. Lemrock operates a complete middleware stack connecting product catalogues, AI agents, and transactions through a single integration point. The company was recently selected to join Agoranov, one of Europe's leading deeptech incubators. It claims that its infrastructure is based on a proprietary architecture built around specialised AI models, trained on the largest independent agentic commerce dataset outside of Big Tech. The company has secured partnerships with over 60 active brands across Europe and the United States, such as Maisons du Monde, Cdiscount, Darty, DIM, Engie, and Lebara. It manages more than 100 million interactions each month.

Lemrock, a French startup enabling brands to appear on conversational AI platforms, has raised $4.6 million from Galion.exe and business angels, with additional debt bringing total funding to $7 million. Founded in 2025, the company helps brands gain visibility on AI chatbots including ChatGPT, Mistral, Gemini, Perplexity and DeepSeek. The startup manages catalogue connections, pricing and real-time availability whilst providing data on consumer behaviour. It has partnered with fintech Tapbuy to integrate payments directly into AI chatbots, positioning itself as comprehensive infrastructure for agentic commerce. Lemrock serves around 60 clients including Maisons du Monde and Cdiscount, participating in over 100 million monthly interactions. The funding will support US market expansion and team growth, with five to seven hires planned short-term.
