Nehos in Belgium — Your AI & Digital Partner for Europe

#Why Brussels needs a different kind of digital agency

Brussels is not a typical European capital for technology services. The city hosts the European Commission, the European Council, the European Parliament, NATO headquarters, and roughly 25,000 lobbyists and public affairs professionals — all operating in a permanent intersection of policy, regulation, and technology procurement. Add Belgium's own financial sector (BNP Paribas Fortis, KBC Group, Belfius, Euroclear), a growing healthtech corridor around Leuven and Ghent, and a public sector that operates in three official languages, and you have a market where generic digital agency services simply do not work.

Organisations operating in Brussels need technology partners who understand three things simultaneously: the technical depth to build production-grade AI systems and modern web platforms, the regulatory knowledge to navigate the EU AI Act, DORA, NIS2, and the European Accessibility Act, and the cultural fluency to deliver in French and English (and often Dutch) across institutional, private-sector, and NGO contexts. Nehos was built for exactly this kind of complexity.

#Nehos in Brussels — our presence and positioning

Nehos established its Brussels office in the Schuman district to be within walking distance of the European Commission's Berlaymont building and the cluster of EU institutions, sector federations, and trade associations that define the Brussels ecosystem. Our Brussels team operates bilingually in French and English as standard, with Dutch available for Flemish institutional clients.

We are not a staffing agency or a body-shopping operation. Nehos is a 50-person product-minded engineering firm that delivers fixed-scope projects with transparent pricing. Our Brussels engagements follow the same methodology we apply to our work with RATP, Groupama, EDF, and Mano-Mano — except calibrated for the specific regulatory, linguistic, and procurement requirements of the Belgian and EU institutional market.

Our Brussels client portfolio currently includes EU-adjacent sector federations, Belgian financial institutions supervised by the NBB and FSMA, NGOs working on European policy, and Belgian technology companies seeking to sell into EU institutional procurement. We bring deep AI engineering capability and EU regulatory knowledge to every engagement.

#Services tailored for the Belgian market

#AI agents — EU AI Act compliant, procurement-ready

The EU AI Act entered into force in February 2025, with high-risk provisions applying fully from August 2026. For organisations in Brussels — whether EU institutions, their contractors, or Belgian regulated entities — AI compliance is not optional. Every AI agent Nehos builds for Belgian clients carries full EU AI Act documentation: risk classification under Annex III, technical documentation per Annex IV, conformity assessment support for high-risk systems (Article 43), and a post-market monitoring plan (Article 72).

Concrete results: a Brussels-based EU sector federation deployed Nehos AI agents for legislative monitoring across 12 policy areas. The system processes EUR-Lex updates, committee documents, and Council working party texts in real-time, reducing manual monitoring time by 65% while maintaining the compliance documentation required for institutional procurement review.

For Belgian FinTech clients, our AI agents additionally address DORA ICT risk requirements (in force since January 2025) and FSMA/NBB supervisory expectations. Every agent deployment includes an ICT risk register addendum, incident classification framework, and third-party risk management documentation.

#Next.js development — trilingual platforms with institutional-grade accessibility

Belgium's three language communities (French, Dutch, German) create unique requirements for digital platforms. Belgian public sector organisations and EU-facing institutions need platforms that work natively in at least two languages, meet WCAG 2.2 AA accessibility standards (required under the European Accessibility Act transposed into Belgian law from June 2025), and handle the content management complexity of trilingual editorial workflows.

Nehos builds Next.js platforms with next-intl configured for three locale groups (fr, en, nl), separate Payload CMS content trees per language community, and EAA-compliant accessibility certification. Our Brussels builds run exclusively on OVH EU datacentres — no US cloud services for production data. For Belgian financial sector clients, our hosting architecture meets the data residency requirements expected by the NBB and FSMA.

#GEO/AEO — visibility in AI search for Brussels organisations

When EU decision-makers search for expertise in ChatGPT, Perplexity, or Google AI Overviews, your organisation needs to be cited accurately. GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) ensure that your brand appears as a credible source in AI-generated answers — not just in traditional Google search results.

For Brussels organisations, this is particularly strategic. EU institutional buyers increasingly use AI assistants during procurement research. Sector federations need their policy positions cited in AI-generated summaries. Belgian FinTech companies compete for visibility against larger European competitors. Nehos's GEO/AEO methodology — our proprietary Citability Score audit — measures and improves your organisation's presence across all major generative AI platforms.

#Legacy modernisation — strangling technical debt without stopping operations

Many Brussels-based organisations, particularly EU agencies and established Belgian financial institutions, run critical systems on legacy architectures: Java monoliths, .NET Framework applications, COBOL mainframe integrations, or aging PHP platforms. These systems work, but they cannot integrate modern AI capabilities, meet current accessibility standards, or support the API-first architectures that EU institutional procurement increasingly requires.

Nehos applies our Legacy Strangler IA-Assisted methodology to modernise these systems progressively. We do not propose big-bang rewrites. Instead, we wrap legacy components in modern API layers, migrate functionality module by module to Next.js and serverless architectures, and integrate AI capabilities at each stage. A Belgian public sector client modernised a 15-year-old case management system using this approach: 8 months, zero downtime, 40% reduction in processing time for citizen requests.

#Key sectors we serve in Belgium

#EU institutions and agencies

Sector federations, trade associations, EU agency contractors, and organisations in the EU institutional ecosystem. We understand procurement documentation requirements, trilingual delivery expectations, WCAG accessibility mandates, and the specific security review processes that EU institutional clients apply to technology suppliers.

#Belgian financial sector

Banks (BNP Paribas Fortis, KBC Group, Belfius), insurance groups, fund administrators, payment institutions, and FinTech companies supervised by the NBB and FSMA. Every financial sector engagement includes DORA compliance documentation, FSMA/NBB-ready audit trails, and EU AI Act risk classification for any AI component.

#HealthTech and life sciences

Belgium's healthtech ecosystem — concentrated around Leuven, Ghent, and Brussels — is one of Europe's strongest. Nehos serves healthtech companies and hospital groups with AI systems that meet both the EU AI Act's high-risk classification for medical AI and Belgium's specific health data protection requirements. HDS-equivalent hosting on OVH ensures data sovereignty.

#Belgian public sector

Federal administrations, regional governments (Wallonia, Brussels-Capital, Flanders), and municipal authorities. Trilingual platforms, WCAG 2.2 AA accessibility, Belgian public procurement documentation, and Beliris/ERDF co-financing compliance where applicable.
