Lēmasonn Consulting

What Lēmasonn Consulting does

Lēmasonn Consulting is a French IT and Business consulting boutique registered as a Société par Actions Simplifiée (SAS) and led by founder-president Léma Sonn. Founded in 2000 and headquartered in Sotteville-lès-Rouen with a second office inside the Village by CA accelerator in Sainte-Clotilde, La Réunion, the firm delivers advisory and execution services across the IT and Business project lifecycle. Its portfolio is organized into six service lines — Expérience client & communication produit, Product management, Cadrage stratégique & vision produit, Gestion de projet & PMO, Go-to-market, and UX Research & UX Design — and a catalogue of nine deployable professional profiles ranging from MOA déléguée and Directeur de projets to Tech Lead and QA/Testeur. The firm positions itself as an embedded extension of client teams during high-pressure periods rather than a traditional advisory practice.

Revenue is generated entirely through professional services engagements sold directly and via referrals and strategic partnerships (notably Village by CA). Pricing is quote-based and not publicly disclosed; the company is bootstrapped with €10,000 of stated capital and no external funding. Customer concentration sits in regulated French enterprise buyers (Crédit Agricole, La Banque Postale, L'Oréal, Sanofi, Printemps, CERP), with additional focus on startups and growth-stage firms accessed through the Village by CA ecosystem and an advisory board that includes CEOs from Octevia, Normandie Web School, and ARI 974. Marketing relies on the lemasonn.com website, Wistia-hosted video, HubSpot and Mixpanel for analytics, and organic SEO.

Operationally, the firm operates with 1–10 employees and has no proprietary software, AI/ML capabilities, patents, or certifications disclosed in the available sources. There is no parent company, no subsidiaries, and no recorded M&A, funding, or regulatory actions. The current strategic posture — building geographic reach into La Réunion, formalizing an advisory bench, and layering inbound marketing tooling onto a historically referral-driven sales motion — is consistent with a micro-boutique attempting to expand footprint and channel mix without scaling headcount or taking on external capital.
