What l'agence123 does

L'Agence123 is a privately held French digital agency founded in 2001 by Douglas Mathon and headquartered in Paris, with additional offices in Bordeaux (opened 2016 under Éméric Riveau) and Bayonne. The agency specializes in the creation, redesign, and migration of e-commerce stores and institutional websites, operating across five core CMS platforms: PrestaShop (where it holds Platinum Partner status and runs an authorized training center), WordPress/WooCommerce, Magento, Drupal, Joomla, and, as of mid-2026, Shopify and Shopify Plus including headless commerce and custom Admin GraphQL app development. Its core technology stack combines PHP/MySQL/JavaScript back-end development with HTML/CSS/JavaScript front-end work, all delivered through a mobile-first responsive methodology and supplemented by ERP connectors for Sage, EBP, Cegid, Odoo, and Divalto.

The agency's service portfolio spans four pillars: web development (front-end and back-end), webdesign and visual identity (UI/UX, wireframing, prototyping, graphic charters), digital acquisition (SEO, SEA, social media management, influencer marketing), and certified PrestaShop training. Revenue is generated almost entirely through professional services, primarily project-based build fees for e-commerce implementations (with a 90-day average delivery window), ongoing maintenance and hosting contracts (often multi-year), retainer-based SEO/SEA campaigns, and training fees from its authorized PrestaShop training center. Pricing is quote-based and customized per engagement with no public price list.

L'Agence123 serves a hybrid segment mix spanning French PMEs through grands comptes, with notable enterprise references including K-Way, Cornilleau, Sebago, Superga, Total, Hector Saxe Paris, Edmond de Rothschild Heritage, and Bellota-Bellota, alongside a long tail of mid-market brands across fashion, food/gastronomy, cosmetics, sporting goods, and energy verticals. Go-to-market is sales-led and consultation-driven via the website, with quoted 24-48 hour response times and dedicated project managers overseeing each engagement. The agency cites a 96% annual client retention rate and over 400 cumulative clients since founding, and holds an unusually dense credential stack including PrestaShop Platinum, Google Partner, Semrush, Opquast (226 best practices), Awwwards Honorable Mention, Fevad Associate Member, and Ecovadis RSE certifications.
