Our methodology

Three founding principles that shape every engagement, regardless of context complexity.

Structure the frameworks

We establish clear reference frameworks in contexts where operational ambiguity is the norm — enabling your teams to act with precision.

Secure the trajectories

Identification of human, organisational and technological risks to ensure project continuity through critical phases.

Deliver real impact

Reliability, discretion and measurable results — in demanding industrial, cultural or institutional contexts.

"This methodology has been applied across diverse contexts — industrial, cultural and institutional — with a constant demand for reliability, discretion and real impact."

Institutional environments High-stakes projects Strategic decision-making Change management Operational intelligence Discretion & reliability Measurable impact Complex environments

Our values

The non-negotiable principles that guide every engagement.

Absolute discretion

Confidentiality is an operational requirement, not an option. Our commitment to discretion is absolute, for every engagement.

Rigour & reliability

Clear reference frameworks, documented processes and flawless follow-through. We leave nothing to chance.

Measurable impact

KPIs defined upfront, traceable results and transparent reporting. No jargon, no hollow promises.

How did Les 3 Colonnes come to be?

What our clients ask us most often

Transparency, rigour and confidentiality — answers to the questions you don't always ask.

The firm is led by its founding partners, each an expert in one of the three divisions (consulting, IT, digital). This structure means a decision-maker — not a salesperson — is your direct contact on every engagement.

We operate in metropolitan France, Reunion Island, Mauritius, Sub-Saharan Africa and Europe. Consulting and digital work 100% remotely. For on-site IT interventions, we mobilise our local partner network.

Systematic NDA before any engagement. No client mention without written authorisation. Infrastructure hosted in France (GDPR-compliant). Discretion is not an option — it is an operational prerequisite.

Because your IT tools, your strategy and your online presence form a system. When three providers work in silos, inconsistencies accumulate. A single contact sees the full picture — and acts accordingly.

Both. Our references include large enterprises (Atos, Thales, E.Leclerc) and SMEs/mid-caps from 10 to 500 employees. The engagement model adapts: fixed-price for SMEs, on-site staffing or long-term missions for larger organisations.

What convinced us was having a single firm that understands our strategy, our IT infrastructure and our online presence. Within 6 months, all three were finally moving forward together.
