Vision

Give Groupe Contex a solid strategic foundation and a concrete AI approach, then move the organization from one-off experiments to structured, repeatable adoption. The ambition: validate a method on a first scope, then extend it to every team, from writing and programming to logistics and sales, in order to embed measurable efficiency gains in existing processes while building team autonomy and consistency across the brands.

Solution

Hologram supported Groupe Contex through a progressive deployment logic: first prove the value on a focused pilot project, then turn that success into a model applicable across the whole organization.

Pilot phase (marketing teams, fall 2025)

After a strategic framing of the group and its sub-brands, the marketing teams of three brands were mobilized around tailored workshops and dedicated CustomGPTs, built from their real pain points. Two concrete solutions were delivered in this phase:

• Writing short and long content for Meta (Facebook and Instagram)
• Writing newsletters, aligned with each brand's tone and standards

Coaching of each brand's AI champions helped refine the prompts and anchor adoption in daily work.

Expansion phase (current year)

Building on the pilot's results, the same model, namely a discovery workshop, mapping of pain points, tailored tooling and champion support, was reproduced with the organization's other teams. Each function was equipped according to its own reality:

• Writing and programming: automated editorial and financial monitoring, including event monitoring, a timeline of decisions, and tracking of tenders and construction permits.
• Logistics: extraction of contract and form data into Excel, production of administrative documents (attendance certificates, exhibitor agreements).
• Sales: meeting preparation dossiers, automated campaign reports, and personalized commercial proposals.

The AI champions network was expanded across the functions to support continuous improvement and sustain the teams' autonomy.

Results

• An approach deployed across the organization: the method proven in marketing was reproduced for the writing, programming, logistics and sales teams, turning a one-off initiative into a structured approach that is consistent across the brands.
• An approach tailored to each team: workshops adjusted to the reality and maturity of each function, making it possible to go further where the context justified it, with additional use cases and enhanced tooling.
• CustomGPTs by team to accelerate and standardize concrete deliverables: meta descriptions (short and long), newsletters, ready-to-send HTML, event and conference descriptions for the website, campaign reports, meeting preparation and prospecting support.
• Lasting gains in autonomy: an AI champions network extended across the organization supports the continuous improvement of prompts and CustomGPTs, well beyond the initial scope.
