Turning data complexity into efficient field execution 

Background: Winning on the shelf in a pressured category
Lactalis Lait operates in a mature French UHT milk market where volumes are declining and regional dynamics vary sharply. With a lean field organization and growing demand for local responsiveness, sustaining performance means focusing teams on the right stores, with the right actions, at the right time.

To sustain performance, Lactalis Lait relies on a powerful field sales organization. Sales Reps are on the front line, responsible for securing availability, growing linear share, and executing commercial agreements across thousands of stores. In that environment, commercial excellence depends on one capability above all: turning complex data into consistent, high-impact action in the field.

The Challenge: Too much information, not enough alignment
Lactalis Lait’s issue was not a lack of data. It was the opposite. Field teams had access to a large and growing volume of resources and information, from market data and routing tools to internal recommendations and store-level indicators. But abundance did not automatically create clarity.

The real challenge was operational effectiveness. Sales reps had to navigate multiple sources, interpret them through their own lens, and decide where to focus first. That created variability in preparation, inconsistency in execution, and a risk that the right actions would not happen in the right stores at the right time. At the same time, both retailers and management expected stronger reporting, clearer ROI, and sharper prioritization.

Lactalis Lait needed to structure decision-making, align headquarters and the field around the same priorities, and ensure that every visit was driven by the best available insight rather than individual interpretation.

The Solution: An activation layer for better decisions
To address this, Lactalis Lait partnered with Whaly to build a centralized activation layer on top of its existing data stack. The ambition was straightforward: give every Sales Rep the right information, at the right moment, for the right store.

The project moved quickly. After a fast industrialization phase, the core model was built in one month and then rolled out at national scale.

Whaly transformed the workflow in two key moments:

  • tick
    At Home (Planning): Reps prepare their week with a clear view of store priorities, identifying where distribution gaps, promotional opportunities, or commercial risks require attention.
  • tick
    In-Store (Execution): Reps arrive with structured, actionable insight, enabling sharper conversations with store managers based on facts, not assumptions, including market share performance and concrete distribution opportunities.

By consolidating fragmented KPIs into a simple mobile interface, Whaly standardized preparation, clarified priorities, and helped turn every Sales Rep into a more consistent and credible commercial partner.

The Results: Measurable impact on commercial performance
The partnership between Lactalis Lait and Whaly did more than improve visibility. It delivered measurable business impact across the organization. The link between Whaly usage and sales performance was clear:

  • tick
    Goal Attainment: “Top Users” of Whaly achieved 88% of their cycle goals, significantly outperforming “Low Users,” who recorded a -14% delta in goal attainment.
  • tick
    Commercial Impact: Active users saw a meaningful lift in Numeric Distribution (DN), especially in the strategic infant milk category, which increased by +2.4 pts.
  • tick
    Linear Share (PDL): Reps using Whaly’s recommendations delivered a +1.3 pt increase in linear share versus their peers.
  • tick
    Adoption & Leadership: The platform reached a 75% adoption rate among Sales Rep. When Regional Directors actively used Whaly, team adoption rose to 80%, confirming its value as both a field tool and a management lever.

Beyond the Dashboard: A new standard for field excellence
For Lactalis Lait, Whaly is not a dashboarding tool. It is an AI copilot built for field sales execution. By consolidating critical signals in one place, Whaly enables reps to prioritize opportunities, organize their week, prepare store visits, generate supporting materials, and enter each conversation with a stronger commercial case.

The value goes beyond visibility. Whaly helps transform raw information into concrete execution levers: recommended actions, visit planning, sales arguments, and operational follow-through. In practice, it gives field teams a smarter way to decide, prepare, and act.

For Lactalis Lait, this means equipping the field with more than insights. It means equipping them with a system that helps convert complexity into commercial action, store by store.




Whaly has become a real modernization lever for our sales organization. The platform was adopted quickly across the field, including by experienced profiles, because the value was immediately tangible: better preparation, clearer priorities and faster access to actionable insight.
