[ Tools & partners ]

The stack we mobilise.

A selection of the technical building blocks Dexon masters in the Custom e-commerce category. The final choice is decided at scoping based on project constraints (performance, scalability, compliance, cost, team).

[ 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.

  • 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.

[ 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.
