About
A firm that turns change into steerable capability
A boutique core, a network of senior experts, and one simple rule: every mandate is delivered by people who have done it before.
The founder
Laurence Poissant
For twenty years, Laurence Poissant has joined organizations at the moment technology changes the rules: web, mobile, media convergence, platforms, automation, and today AI. Digital leadership in a major media group, transformation of a cooperative network, multi-division marketing leadership: every chapter follows the same method — read the disruption, decide, install the system, measure.
Medialys was born from one observation: mid-size organizations in Quebec lack access to growth leadership of this caliber — large firms ignore them, agencies execute without a frame, and hiring a full-time senior executive is not always the right first step. The answer: framed mandates, published pricing, and a model where strategy and execution are never separated.
The Groupe Medialys model
Groupe Medialys is a boutique firm: a permanent core that frames, steers and answers for results, surrounded by a network of senior experts mobilized per mandate. You get large-firm depth at compact-team cost structure.
- The team is sized to the mandate: you pay for the required expertise, not overhead.
- No junior associate doing the work: every practitioner has 10+ years in the field.
- One accountable point of contact for results, from first call to final deliverable.
