The Paris-based startup Lemrock has secured €6 million in funding to establish itself as the commercial framework within AI agents.

      Founded only a few months ago by two experienced Y Combinator founders and a retail expert, Lemrock is betting that AI agents are emerging as the new storefronts, while brands are not quite prepared for this shift. When seeking recommendations for running shoes from ChatGPT or Perplexity, there needs to be assurance that the correct brands are featured, the pricing is accurate, and that purchases can actually be completed.

      Lemrock, a startup based in Paris established in 2025, is developing the necessary middleware and has recently secured €6 million ($7 million) to implement it.

      The funding round was led by Galion.exe, a seed fund supported by a community of over 400 French tech founders. Participating in the round are several knowledgeable retail investors including Michaël Benabou, a co-founder of Veepee (previously Vente-Privée, a key player in France’s e-commerce scene); Gary Anssens, who founded the online cycling retailer Alltricks, later acquired by Decathlon in 2019; retail tech investor Frédéric Halley; tech and retail investor Emmanuelle Brizay; and Antoine Lizée from Alan, a French health insurance startup.

      Importantly, Jean-Baptiste Rudelle, co-founder of Criteo, the Paris-based adtech giant that popularized programmatic advertising, not only invested through his role on Galion.exe’s investment committee but has also joined Lemrock’s board of directors.

      Lemrock’s concept is simple: e-commerce is transitioning from search engines and brand websites to conversational AI interfaces, and the infrastructure that brands require to operate in this space is currently lacking.

      The startup provides a single integration point that links a retailer’s product catalog to major AI platforms like ChatGPT, Claude, and Perplexity, managing real-time pricing and availability, transaction processing, and performance tracking all within one framework. Brands retain control over their data, pricing, and the presentation of their products.

      The opportunity identified by the founders is structural. Lemrock indicates that some retailers are already seeing traffic reductions of up to 30% as consumers shift from Google searches to AI agent inquiries.

      The reasoning is clear: if consumers are no longer visiting your website, it’s crucial to be available and able to transact where the customers are present.

      “Conversational commerce changes the dynamic: it’s no longer the customer searching for a product; it’s the right product reaching the right customer,” explained Roxane Laigle, the CEO of Lemrock.

      “Our technology enables brands to sell more effectively, while also allowing consumers to buy in a better, quicker, fairer way with less friction.”

      Lemrock was co-founded by three individuals with complementary backgrounds that align closely with the problem at hand. Laigle brings over ten years of B2C growth and retail experience from her time at Fnac Darty. CPO Sasha Collin and CTO Clément Nguyen are both veterans of Y Combinator’s S24 batch, where they co-founded Mindely, an AI-driven interviewing platform.

      Collin has three years of experience at QuantumBlack, McKinsey’s AI division, while Nguyen has a background in adtech and retailtech from his time at Rakuten Advertising. Officially registered as Lemrock AI SAS in December 2025, the company is located near Paris.

      Lemrock has also been selected for Agoranov, one of Europe’s leading deep-tech incubators, which adds institutional credibility to the team’s qualifications.

      The broader landscape is competitive yet still developing. Perplexity is also enhancing its commerce capabilities, and several early-stage startups, including New Era of Shopping from Budapest and San Francisco, are pursuing similar goals.

      What Lemrock is offering is a vendor-neutral middleware layer rather than a competing storefront: one integration, multiple AI platforms, designed to safeguard brand integrity.
