Didaxis

What Didaxis does

Didaxis is a French portage salarial (payroll umbrella) company founded in 2004 and headquartered in Versailles, operating as a SAS with €1M of share capital. The firm provides employment infrastructure for independent consultants — handling employment contracts, payroll, social contributions, liability, training, and benefits — allowing freelancers to operate as salaried employees while contracting with end clients. Didaxis serves more than 2,000 active consultants across a range of sectors including IT, engineering, human resources, training, and commercial functions, distributing this activity through 16 physical agencies across France plus digital onboarding channels.

The company's core operational asset is EOLYS, a proprietary management platform that covers consultant onboarding, mission management, billing, social declarations, and CRM functionality. Didaxis also owns Kicklox, a freelance mission-matching platform with a community of 170,000+ registered experts that serves as a supply-side funnel and adjacent distribution asset. The firm has progressively extended its product set beyond traditional portage salarial into Employer of Record (EOR) services for international clients hiring in France, Qualiopi-certified continuing-education training ("Formation"), and a dedicated "Portage Commercial" module for business-development freelancers. The business model is a management-fee take rate on consultant gross billing, supplemented by training and EOR revenue.

Didaxis is the first French portage salarial company to obtain AFNOR FEPS certification and holds additional certifications including Qualiopi (training), EcoVadis (sustainability), and CNIL registration (data protection); the company is also a participant in the UN Global Compact. Leadership is anchored by founder and President Guillaume Cairou, with Céline Romain serving as Commercial Director. Revenue is not publicly disclosed, and the firm appears to be privately held and bootstrapped with no reported external funding rounds.
