EOLIS

EOLIS supplies digital, marketing and sales specialists to companies in Belgium through what it calls modular in-housing. It says this goes beyond staffing and consulting, because specialists are embedded directly in the client's teams rather than the work being sent elsewhere.

The company offers three services. Experts on demand provides freelance digital, marketing or sales talent for niche skills or extra capacity, such as a digital marketing specialist, copywriter, UX designer or product owner. Hybrid in-house teams are purpose-built teams that work day to day inside the client organisation. Organisational design covers team structures, roles and processes. It also advertises freelance and permanent roles to candidates, with open positions in Brussels in UX and marketing.

EOLIS has its office in Brussels, and Klaas Vandeputte is named as CEO. It reports more than 100 active consultants, 50 projects in 2025 and over 20 years of experience. Its work includes projects for Proximus and BNP Paribas Fortis, and it says it has embedded specialists and teams in finance, telecom, retail and other sectors.
