What Lemrock does

Lemrock is a Paris-based B2B software company that builds middleware infrastructure for agentic commerce, founded in 2025 by Roxane Laigle (CEO, ex-Fnac Darty), Sacha Collin (CPO, ex-QuantumBlack, Y Combinator), and Clément Nguyen (CTO, Y Combinator repeat founder). The company's core product, Agent Storefront, ingests enterprise retailers' product catalogs and structures them for interpretation and retrieval by large language models, enabling product discovery, personalized recommendations, and real-time transactions directly inside conversational AI environments such as ChatGPT, Claude, Perplexity, Mistral AI, Gemini, and DeepSeek. The platform combines catalog ingestion, hyper-personalization via proprietary intent classification and taxonomy mapping models, and an LLM orchestration layer that enables brand voice control and AI-powered sell-and-conversion workflows, claiming to process over 1 billion queries per year across 10M+ live products.

The business model is B2B middleware sold to enterprise retailers and brands on a quote-based, demo-driven sales motion, with revenue derived from subscription/recurring platform access and technology licensing for transactional agentic commerce flows. Pricing is not publicly disclosed. The company targets brands and retailers seeking to maintain visibility and direct customer relationships as commerce migrates from traditional websites to AI agent interfaces, with priority markets in France, the US, and the UK. Lemrock reports 60+ brand customers including Maisons du Monde, Cdiscount, Darty, DIM, Engie, and Lebara, and processes more than 100 million AI interactions per month, with claimed 10x ROAS versus traditional digital commerce channels.

In March 2026 Lemrock closed a €6 million seed round led by Galion.exe with Criteo co-founder Jean-Baptiste Rudelle (now on the board) and Veepee's Michaël Benabou participating; a follow-on from Gharage Ventures was added in May 2026. The team is incubated at Agoranov and was selected for Station F's inaugural F/AI accelerator cohort. The company holds GDPR compliance certification and employs 1–10 people as of the most recent data.

Direct peers

• Algolia: Enterprise search and discovery API used by retailers and brands; competes in the same product-discovery-for-commerce category and has launched AI-powered personalization features directly comparable to Lemrock's intent matching.
• Klevu: AI-driven search, merchandising, and personalization SaaS for e-commerce stores; serves a similar mid-market and enterprise retailer base with comparable AI-search and recommendation capabilities.
• Coveo: Enterprise AI-search and relevance platform with commerce-specific personalization; overlaps with Lemrock's intent classification, LLM orchestration, and product-discovery value proposition for large enterprise customers.

Broad incumbents

• Criteo: Global adtech/retail-media platform with deep retailer relationships; an investor's Criteo co-founder sits on Lemrock's board, and Criteo has the resources and retailer data to enter agentic commerce directly.
