We build and run the software and networks Maghreb–Europe operators depend on — sector platforms, AI, IoT and connectivity, engineered since 1991.
Expertise
We design and operate sector platforms — and still deliver offshore engineering, integrated telecom and connectivity (private 5G, UCS, point-to-point and VoIP), legacy migration, and consulting when the operating model demands it.
We modernise critical operations by moving organisations from legacy systems to coherent platforms that absorb new technologies and new capabilities. That means controlled migration of data and processes, redesigned workflows, BI that leaders can trust, and selective integration of AI and IoT — so the business gains speed and visibility without freezing day-to-day work.
AI in service of operations. We embed OCR, knowledge retrieval (RAG), chatbots, copilots and assisted triage inside operational workflows. When data must stay on site, we deploy local or on-premises options. Human validation remains mandatory on critical and compliance steps.
Device connectivity, edge processing, and operational dashboards that support maintenance and control decisions for medical equipment, industrial assets, smart sites and smart cities.
Our method: design, integrate and operate critical connectivity — private 5G, UCS, point-to-point and VoIP — to open underserved regions and enable remote work, telemedicine and distance learning. The product catalogue (UCS, phones, antennas, LTE/5G) lives under Connectivity.
Connectivity
An integrated connectivity offer we deploy in production conditions: UCS/PBX, VoIP phones, point-to-point antennas and LTE/5G — for operators, enterprises and public networks. We deliver project-oriented solutions that combine hardware and software in one coherent rollout.
Cloud and multi-tenant PBX for operators who want to sell business voice and collaboration as a service — the control of a classic on-premise exchange, without locking every customer into their own hardware stack.
Desktop and wireless SIP endpoints built for daily desk use: clear audio, simple interfaces, and secure integration into existing UCS/PBX and carrier SIP trunks.
Long-range, high-throughput wireless links for private networks — when fibre is late, costly or impossible, and the link still has to be stable for operations.
From all-in-one CPE to core building blocks — mobile broadband for enterprises, ISPs and smart-site programmes that need low latency and predictable coverage.
Platforms
Each platform brings together business expertise, modularity and technology. Functional coverage is built for real field use: operational workflows, security and simplicity. Stack, integrations and AI, IoT or telecom building blocks are chosen to deploy and operate for the long run.
Software · AI · Multisector: Telecom, IT, Pharmaceutical, Medical equipment
Multisector RFP and tender automation — from DCE analysis to collaborative Go/No-Go, with local AI and multi-tenant security.
Win more tenders with a Go/No-Go decision in hours, not weeks — without losing human control.
Software · Fintech
Agency cash remittance for transfer networks — counter workflows, compliance controls, and mobile apps for senders and ops leaders.
Run cash remittance counters with fewer errors, clearer cash control, and apps your agents actually use.
Software · AI · Insurance
Multi-country insurance lifecycle — quote to policy to claims to billing and reinsurance, with agent and policyholder portals.
Unify quote-to-claim across countries so pricing, fraud checks and portals stop living in separate silos.
Software · Marketplace
Maghreb multi-vendor marketplace for buyers and SME sellers — catalog, checkout, vendor operations, and delivery in one platform.
Give SME sellers a full marketplace path — catalog to delivery — without stitching five tools together.
Software · AI · PropTech
Maghreb real-estate SaaS: property marketplace, agency CRM, and an AI copilot for listings, pricing, and deal follow-up.
Help agencies publish, qualify and close Maghreb deals faster — including diaspora buyers thinking in EUR/USD.
Software · AI · PropTech
Co-ownership and syndic management — incidents, general assemblies, finance, and maintenance, with privacy-minded local AI.
Cut syndic firefighting: one system for incidents, AG, dues and maintenance that residents can also see.
Software · Healthcare
Medical tourism for Morocco and Tunisia: compare clinics, book stays, and follow care with human validation on sensitive steps.
Turn medical-tourism enquiries into a tracked care journey — clinics compared, stay booked, sensitive steps human-gated.
Software · AI · Hospitality
Riad and guesthouse operations — calendars, reservations, AI-assisted reviews, upsells, and owner trust reporting.
Stop juggling OTAs and spreadsheets: one calendar, trusted reviews and upsells for riads and guesthouses.
Software · AI · Education
Distance-learning platform for universities, academies and corporate academies — courses, live sessions, assessments and learner progress on one stack.
Run remote and hybrid programmes with clear pathways, tracked progress and content that stays easy to operate.
Software · AI · Healthcare
Telemedicine for clinics and care networks — secure video consults, triage, e-prescriptions and follow-up, with mandatory human validation on clinical steps.
Extend care beyond the waiting room without losing clinical control, privacy or auditability.
Software · IoT · Industry
CMMS for plants and facilities — work orders, assets, preventive plans and spare parts, with optional IoT signals for condition-based maintenance.
Cut unplanned downtime: one system for assets, interventions and parts — visible to planners and field teams.
Software · Analytics · Oil & Gas
Digital oilfield HQ platform for gas corridors — compression-station performance, transport programmes and exploitation KPIs, from the executive dashboard down to the asset.
One HQ layer to compare sites, track the day programme and drill into machine detail — faster decisions, shared language between headquarters and central dispatching.
Software · Oil & Gas · HSE
Health, Safety & Environment platform for midstream and corridor operations — incidents, permits to work, observations and compliance, aligned with how IOC and site teams run gas compression and pipeline assets day to day.
One HSE system of record from HQ to station: fewer spreadsheet silos, faster close-out of actions, and auditable proof when regulators or partners ask.
About
A history of expertise. An ambition without borders.
3s2i Group was founded in 1991 on a simple conviction: technology only creates value when it is tailored to the business, deployed with reliability, and built to last.
3s2i International (Tunis) is the group’s engineering headquarters. Lixeo (Brussels) and Lixeo Maroc (Casablanca) are the European and Moroccan entities of the same group — consulting, VAN and e-government — so clients stay close to delivery on every corridor.
For more than three decades, we have supported enterprises, public institutions and industrial operators across Europe and the Maghreb — turning complex challenges into concrete, durable solutions.
Today, artificial intelligence, software engineering and connected systems sit at the heart of our approach. Not as trends, but as levers we master and adapt to each client, in each context.
Four delivery centres. Hundreds of projects. One philosophy: your success is our signature.
Four countries, two continents — development centres close to Maghreb and European clients.

Proof point · Anonymised engagement
A manufacturing group needed reliable B2B document exchange across Tunisian production sites and European trading partners — without fragile email attachments or one-off file drops.
We designed and operated an EDI/VAN delivery model from our Maghreb centres: message mapping, partner onboarding, monitoring, and a control path aligned with European buyer formats.
A corridor operated continuously over multiple years: stable daily exchange (orders, notices, logistics documents), industrialised partner onboarding, and a clear drop in manual rekeys on both plant and buyer sides.
