What Aressy does

Aressy is a B2B marketing and communication agency headquartered at 48 rue Croix des Petits-Champs in Paris (75001), France, and operated by the legal entity Epoka SAS (capital social €44,958) within the Epoka Group. Approximately one year after its rapprochement with the group, the brand was rebranded to Agence Mantu and redirected to agence.mantu.com, with the Aressy site still publicly accessible. The agency positions itself as the first independent French agency dedicated to Corporate & BtoB communication, and describes its offering as an integrated "Brand to Business" approach that combines brand storytelling, content creation, media buying, digital experiences, social influence, and demand generation. Six service lines are documented: Brand Experience, Content Activation, MediaDesk (B2B programmatic media buying), Digital & Data, Influence (social), and Business Acceleration (lead generation and ABM). Delivery is structured around a proprietary five-factor methodology called ETHOS for Account-Based Marketing campaigns.

Underlying technology is a stack of third-party marketing automation and CRM platforms deployed across client engagements rather than a proprietary platform: Oracle Marketing Cloud Eloqua, HubSpot, Microsoft Dynamics CRM, and Click Dimension. The agency's technology differentiation rests on the ETHOS methodology and a rich thought-leadership content library (e-books, whitepapers, the L'Écho BtoB podcast on five major platforms, and case studies). The go-to-market is sales-led B2B, with direct client engagement from the Paris headquarters augmented by the Worldwide Partners International BtoB network (WPI), which extends delivery through partner agencies in Paris, London (Clear B2B), and Chicago (Slack & Company). The agency serves enterprise and mid-market clients across automotive, software, telecom, financial services, industrial, cybersecurity, cloud, luxury, and ESG verticals, and has won BtoB Leaders Awards in ABM (Gold, GCollect) and Client Content Influence (Silver, XDI x Solidworks).

The revenue model is professional services on a project and retainer basis, with pricing not publicly disclosed. The agency monetizes through campaign execution, content production, media planning and buying, ABM programs, and brand strategy engagements for B2B clients in France and internationally. Customer segments are horizontal across B2B companies, with case studies spanning both enterprise and SMB engagements, and the channel mix combines content marketing, organic social, paid programmatic, events, and co-organized industry summits to generate demand.
