What CustUp does

CustUp SARL is a private French boutique consulting firm (SARL, registered capital €5,000) headquartered in Croissy-sur-Seine, founded circa 2016 and operating with a headcount of 11-50 employees. The firm positions itself as an operational marketing-sales consultancy—bridging business and IT disciplines—that helps enterprises structure and exploit their customer data and marketing technology (MarTech) ecosystem, including Customer Relationship Management (CRM), Customer Data Platforms (CDP), Référentiel Client Unique (RCU), Customer Engagement Platforms (CEP), Contact Center / Gestion de la Relation Clients (GRC), and subscription business models. Service offerings are organized into five practice areas: Conseil CRM, Conseil Données Clients, Conseil Centre de Contact, Conseil Abonnements, and Conseil Relation Clients. CustUp describes its methodology as 'operational consulting'—going beyond strategic recommendations to tool configuration, deployment management (AMOA), and skills transfer to client teams, capitalizing on existing client assets rather than recommending complete MarTech overhauls.

The firm's go-to-market is sales-led and content-driven: an SEO-optimized French-language blog, gated whitepapers, and four segmented email newsletters drive inbound demand, with direct enterprise sales engagements closed via website contact forms and phone outreach. The customer base is horizontal across B2C and B2B enterprises in France, with named case-study references spanning retail (Altarea Cogedim, Virgin Megastore), publishing (Fiscalonline, Lefebvre Dalloz), media (Unique Heritage Media), and marketing/advertising (Wunderman Thompson). Co-produced whitepapers with CDP vendor imagino and data marketing agency Meteors indicate a partnership-driven ecosystem posture. The firm holds GDPR/CNIL declaration n°1941450 and training organization approval n°11788335478 (Datadock-referenced), enabling both consulting and billable training engagements. Pricing is quote-based and undisclosed; industry benchmarks cited in the firm's own content suggest typical project sizes of €30k-€200k. CustUp reports no disclosed revenue, no external funding, and serves exclusively the French market.
