ARTHUSA INC.

What ARTHUSA INC. does

ARTHUSA SARL (operating as ARTHUSA INC.) is a French boutique management consulting and corporate training firm headquartered in Lyon, with stated headcount of 1-10 and a wider network of certified coaches and interveners. Founded in 2000 by Pascale and Philippe Crouy and joined in 2014 by their sons Olivier and David, the company acquired the GO method in 2004 and developed it into the proprietary GSI (Go-System International®) methodology — a maieutic, non-directive facilitation approach using corporate storytelling, collective intelligence, and practical toolkits to transform managerial behavior.

The product surface is organized around three structured AES programs (Leadership — 7 days, Management — 7 half-days, Agility — 4 half-days for CODIRs), a modular remote/in-person offering called Le Lab' Arthusa (3 × 4-hour sessions on themes such as communication, emotions, conflict management, self-knowledge, collective intelligence, and time management), and a change-management suite covering individual coaching (Flash and Confidence), team cohesion seminars, co-development/APP sessions, CODIR accompaniment, collective diagnosis, and corporate-project design. All delivery is founded on the GSI base methodology and the in-house intervenor network that includes former senior executives such as Admiral Olivier Lajous, ex-DRH of the French Navy.

Revenue comes exclusively from bespoke professional-services fees — intra- or inter-company engagements sold via direct enterprise field sales to clients in Industry/Manufacturing (Setforge, SEB, Sigvaris, Piveteau Bois, Vivre en Bois, Samson, Clasquin, Cougnaud, Minakem, CERATIZIT, OHG), Healthcare (CHRU Lille/Grenoble/Montpellier, Mutuelle Paca, FM, Aralis), Financial Services (Crédit Mutuel Océan), and the public sector/SDIS (SDIS 72, SDIS 85, MNSPF, DGSC). Growth is driven primarily by referral, long-tenured multi-year engagements (e.g., 10+ years at Setforge across 9 subsidiaries), and cascade effects where trained managers become internal GSI facilitators. Pricing is not publicly disclosed; engagements are quoted based on scope.
