Why clients call
You call us to inform a complex decision, sometimes an urgent one
Anticipate
Your hosting contract expires in eighteen months and you want to decide on figures, not on assumptions.
Improve
Your cloud bill is rising faster than your usage, and nobody can explain precisely why.
Decide quickly
A client demands proof of your compliance, and you have no dedicated team to build it.
Our method
We do not take your place. We put you in a position to hold it.
01
Assess
We measure before we recommend. Costs, emissions, compliance gaps, the real state of the infrastructure: our tools produce figures, not impressions.
02
Equip
We build our own AI analysis tools. They turn what was measured once a year into something measured continuously.
03
Train
We pass on the methods we apply. A framework your teams cannot keep alive will not last six months.
04
Steer
We take charge of the matters too critical to be learned along the way, and we hand them back.
At the end of every engagement, one deliverable carries this title: what your teams can now do on their own.
Delivery
Running a project is a profession. It has been ours for twenty years.
A recommendation that is not carried through remains a document. Our partners have led programmes worth tens of millions of euros, information system mergers and carve-outs, data centre builds and production migrations.
Green PMO, which we created, extends that discipline to environmental matters.
Cross-cutting method
Green PMO · registered trademark
It is not a fourth practice: it is what runs through all three. A PMO orchestrates project governance; we have extended its scope to environmental matters.
The partners

Artificial intelligence
We advise on AI because we use it every day
Framing and prioritising use cases, governance and compliance with the European AI Act, sovereign infrastructure, footprint assessment: AI runs through all three of our practices. It does not form a fourth.
We also build our own analysis tools, for our own engagements, for assisted audit and investigation. That is what entitles us to speak about it.
The Academy
We train in the methods we apply
Six modules for running your work with AI: project management, agile, Lean 6 Sigma, FinOps, GreenOps, cybersecurity. Designed and delivered by practitioners, from cases drawn from our engagements.
We do not only advise on infrastructure. We are building one.
Green DC is a venture led by our partners: local data centres dedicated to intensive computing, coupled with local energy production units. Computing is looking for energy. Regions already produce it.
Separate entity and brand. Green DC does not appear in Esiense's navigation.
