[ Tools & partners ]
The stack we mobilise.
A selection of the technical building blocks Dexon masters in the Custom applications & backends category. The final choice is decided at scoping based on project constraints (performance, scalability, compliance, cost, team).
[ Modular ]
30 to 50%less cost and time, with no compromise on quality.
An internal library of over 300 code modules, ultra-functional and 100% customisable. You pay for the assembly and personalisation, not for reinventing the wheel.

[ Additional services ]
Two complementary missions
to activate whenever you want.
Beyond the main service, we step in upstream (audit, scoping) or for long-term coverage (governance, delivery, operations). We choose together the formula that fits the timeline.
- SERVICE · 01Audit · Scoping · Strategy
Audit, Advisory & Project scoping
Before building, we look at things clearly. Audit of the existing, scope definition, technical choices, costed plan of attack. The phase that prevents surprises 6 months later.
Let's discuss your project - SERVICE · 02Think → Build → Operate
Governance, delivery & operations
We stay with you across the three phases: strategic governance (Think), daily delivery (Build), operations and continuous improvement (Operate). No handoff, no switching.
Let's discuss your project
[ The agency ]
A team that outsources nothing.
Designers, developers and project managers under one roof. No cascade of agencies, no pivot freelancers, no imposed proprietary framework. You speak to the people who write the code.
A 30-engineer team under one roof is the right size to hold a complex project without delegating what matters.
- UX · UI · CodeUnder one roof. No external handoff.
- QAMOE + MOA + UAT systematic.
- MaintenanceCorrective, preventive, evolutive. Long-term.
- Tax incentiveInnovation Tax Credit certified · up to 20% tax credit.

[ Follow-up ]
A dedicated project manager, reachable every day.
Your project manager runs the daily stand-ups, project committees (COPROJ), and stays available for any cross-cutting question. No intermediary between you and the team writing the code.
[ Industries ]
Built for your business.
We step in where business complexity is real. Five industries where Dexon operates regularly since 2024.
Industry
Shop-floor monitoring, production traceability, custom MES tools.
Healthcare
Patient apps, teleconsultation, HDS-compliant record tracking.
Transport
Route optimisation, fleet management, field-ops apps.
Finance
Management platforms, compliance, banking integrations.
Sport
Club & federation apps, ticketing, fan experience.
[ Our AI stance ]
AI-augmented approach,
supervised by experts.
We use artificial intelligence as a lever for acceleration and optimisation within our technical processes, while keeping strong human oversight on every strategic phase of the project.
AI improves productivity. It does not replace:
- field experience
- architectural expertise
- understanding business stakes
- technical governance
- complex trade-offs
- cybersecurity
- operational accountability
Our teams act as a layer of validation, quality control, security hardening and steering, to ensure reliable, scalable deliverables that can operate in real-world environments.
