What EOLIS does
EOLIS is a Brussels-headquartered professional services firm that operates a modular in-housing model for enterprise and mid-market clients in Belgium. The company embeds digital, marketing, and sales specialists directly inside client organizations as integrated team members, rather than dispatching them as external contractors. Its service portfolio spans three core lines — Experts on Demand (individual specialists for skill gaps), Hybrid In-House Teams (purpose-built teams working alongside client staff), and Organisational Design (advisory on team structure and processes) — supplemented by specialized capabilities including UX design, UX copywriting, conversational design, marketing automation (HubSpot), coaching, product owner staffing, and content/campaign management. EOLIS does not sell software; its core technology is its proprietary matching methodology and the curated community of 100+ continuously trained consultants it draws from, accessed operationally through the Loxo recruitment platform.
The company generates revenue through negotiated professional services fees billed to clients for consultant time, engagement scope, and contract duration, with pricing conducted on a quote-based, non-publicly-disclosed basis. Go-to-market is a sales-led direct enterprise motion in Belgium only, with no self-serve channels, marketplace listings, or cross-border operations. Sales is managed by dedicated business managers (Raf Van Puyvelde, Sacha Schuerewegen, Amira El Haddaji, Mickaël Nosy) operating from a single headquarters at Koning Albert II Laan 4, Brussels. The client base is concentrated in Belgian enterprise — logos include AXA, Belfius, ING, BNP Paribas Fortis, KBC, Keytrade Bank, Colruyt, Renault, VRT, and Proximus — spanning financial services, telecom, retail, automotive, and broadcasting.
EOLIS is privately held, founder-led by CEO Klaas Vandeputte, with no disclosed institutional investors. In March 2025 the company merged with 4P square, a Belgian marketing and sales consulting firm founded by Raf Van Puyvelde, creating a combined group of 100+ collaborators targeting €12 million in combined turnover for 2025. Post-merger, the 4P square brand is retained under the EOLIS umbrella and Van Puyvelde serves as Strategic Business Director. The company has grown to 19 direct employees (with the larger workforce operating as a consultant community rather than full-time staff), maintains active content marketing and thought leadership under Vandeputte, and shows no public-market listing, patents, regulatory actions, or external funding rounds.
