What Resoneo does

Resoneo is a Paris-based digital marketing consulting firm founded in 2004 by four partners — Richard Strul (President), Sébastien Broussois (Director of Acquisition), Olivier de Segonzac (Director of SEO), and Stéphane Philippo (Financial and Administrative Director) — operating today with 90+ expert consultants serving 170+ active clients across 23 markets and 17 languages. The firm positions itself as a specialist boutique (rather than a 360-degree agency) in SEO, Search & Shopping (SEA), Display & Social Ads, Analytics & Data, GEO (Generative Engine Optimization), and AI-applied search marketing. Named enterprise clients span retail (Leboncoin, BUT, Bricomarché, Okaïdi, Linvosges, Atlas For Men, Carrefour Traiteur, Salomon, Feu Vert), insurance (Generali France), healthcare (Laboratoires Dermatologiques Ducray / Pierre Fabre, Fondation pour l'Audition), travel (Easyvoyage, UCPA, Voyage Privé), real estate (Bouygues Immobilier), financial services (CAFPI), and technology (Dassault Systèmes, DocuSign), with several multi-year engagements dating back to 2015-2018.

The company's competitive backbone is its proprietary technology platform MATRICEO, developed over 20 years through a dedicated R&D function and encompassing 80+ internal tools (of which 30 are AI-powered). Notable sub-products include Data Valorisation (extended Google Search Console analytics with omnichannel crossing), Prometeo (SEO traffic prediction by topic and scenario), Prometeo Labs (AI tool library), Ozé (news-engine performance tracking), GoogleYou (Google Suggest monitoring), a custom web crawler, the resoneobox page generator (launched 2009), and the ChatGPT Search Capture Chrome extension (launched March 2026) for real-time LLM search monitoring. The firm holds top-tier platform certifications across all four major ad ecosystems: Google Partner Premier (top 3% globally), Google Comparison Shopping Premium Partner (via the Yteo CSS sub-brand, certified in all available CSS countries), Microsoft Advertising Elite Partner, Meta Business Partner, and Criteo Premium Partner. It is also recognized as the first French agency with Google International Growth Partner status (20/20 score, 2025), holds EcoVadis Silver (top 15% for ESG, since 2021), is a UN Global Compact signatory (since 2019) and SBTi commitment holder (since 2023), and has won multiple SEMY Awards between 2017 and 2026, including the 2026 "Personnalité Search de l'Année" awarded to co-founder Olivier de Segonzac.

Resoneo's revenue model is professional services: consulting missions, staff augmentation (régie), and retainer engagements sold directly through a Paris-based commercial team, supplemented by a separate training/formation offering with partially-disclosed per-participant pricing (€1,050-€1,200 excl. VAT for the publicly listed courses). The firm is privately held by its founding partners, was expanded in 2023 when five historical collaborators were elevated to partner status, and operates from its headquarters at 60 rue de Wattignies, Paris 12th. No external funding rounds, acquisitions, or parent-company relationships have been disclosed; Resoneo's English name is Resoneo (styled RESONEO).
