What Expert-Marketplace.fr does

Expert-Marketplace.fr (legal entity JLB CONSULTING SAS, SIREN 917 895 179) is a Toulouse-based B2B consulting agency that manages brands' presence on Amazon and 25+ European marketplaces. Founded circa 2009, the firm has operated for over 15 years with a deliberately narrow focus on marketplace operations — Amazon Seller/Vendor Central management, Amazon Ads (Sponsored Products, Sponsored Brands, Amazon DSP), A9/A10 SEO, multi-marketplace feed management, and private sales on Veepee, Showroomprivé, BazarChic, The Bradery, Westwing, QoQa, and DeinDeal. The agency holds Amazon Ads Advanced Partner and Lengow Certified Partner statuses and integrates third-party tooling (Lengow, Channable, Shopping Feed for feeds; Shippingbo for orders; Helium 10 for keyword research) into a single 360° managed service offering for mid-market consumer brands.

The firm's revenue model combines monthly retainer-based professional services with advertising management fees on approximately 100k€ of monthly ad spend across client accounts. Client acquisition is sales-led: a free 30-minute audit booked through Calendly serves as the lead magnet, with content marketing (a practitioner-authored blog led by CEO Johanna Bloch) and organic SEO driving top-of-funnel demand. Named clients include Women Warriors, Teddy Smith, Serge Blanco, Holy, Aum World, Nyte, My American Market, Hypnia, Carea, and Concept Usine, with a heavy concentration in apparel, footwear, and lifestyle. The agency reports a 98% contract renewal rate and a 3-year average client tenure.

The company operates with 1–10 employees, functions as a privately held SAS with no disclosed institutional investors or external ownership, and serves brands primarily across France, Germany, Spain, Italy, the Netherlands, and Switzerland. The published 80M€ headline figure is cumulative GMV across managed client accounts — not company revenue. Note: firmographic data conflicts on founding year (firmographics lists 2022; company history and "15+ years" claims support 2009); the analytical view treats 2009 as the operative founding date given the explicit tenure claim and detailed timeline.
