Introduction
Marketing Mix Modeling for agencies has become the critical differentiator between tactical service providers and true strategic growth partners. Furthermore, as CMOs face mounting pressure to demonstrate marketing’s tangible business impact, agencies capable of quantifying both short-term performance and long-term brand value now command premium market positions.
This case study examines how INSIGN ,an independent strategic and creative consultancy with 250+ consultants, fundamentally transformed its client advisory capabilities through Marketing Mix Modeling. Specifically, under the leadership of Damien Schoennahl (Senior Partner and General Manager) and Arthur Gaudrie (Lead Product Manager for OnePlatform), this France-based agency partnered with MASS Analytics to evolve beyond fragmented measurement toward holistic marketing intelligence.
MASS Analytics enables agencies to speak the language of business impact rather than just marketing activity. As a result, INSIGN achieved a fundamental market position shift: from campaign executors to trusted C-suite advisors, now possessing the rare capability to isolate marketing’s true contribution amid complex business dynamics.
The Challenge: Breaking Free from Fragmented Measurement
Like many agencies, INSIGN previously relied on standard analytics solutions, pre-and post-tests, and their proprietary “OnePlatform” to evaluate marketing performance. However, while these tools provided useful snapshots, they couldn’t deliver the complete picture modern clients increasingly demand.
Partial measurement creates partial confidence. Therefore, in an era of tightening budgets, “useful fragments” prove insufficient, agencies need undeniable proof of impact.
Moreover, these limitations became critical as market pressures intensified:
The CMO Credibility Gap With budgets tightening and marketing leaders increasingly relegated to “communications manager” status, INSIGN needed to prove that marketing drives business strategy, not just advertising efficiency. Unfortunately, standard tools couldn’t connect campaigns to broader business outcomes influenced by brand equity, distribution, pricing, and macroeconomic forces.
Isolating True Campaign Impact Pre-tests and post-tests failed to separate marketing effects from seasonality, halo effects, competitive activity, and economic shifts. Consequently, without this isolation, recommendations risked attributing success (or failure) to the wrong factors entirely.
The Strategic Ceiling Existing measurement approaches limited INSIGN’s conversations to marketing directors. To overcome this, the agency needed a more robust, business-credible methodology to access general management and finance teams which are the real budget authorities.
MMM opens doors to the C-suite because it speaks the language of ROI, not merely reach and frequency.
“We needed to move beyond partial measurement. Pre-tests, post-tests, analytics…they’re useful, but they only give fragments. What we wanted was the big picture.” — Damien Schoennahl, Senior Partner, INSIGN
The Solution: A Partnership Built on Education and Autonomy
INSIGN selected MASS Analytics based on our distinctive educational approach and MassTer’s unique balance between technical sophistication and genuine business accessibility.
The best agency partnerships don’t make you a middleman, they make you the expert. Thus, we build your capability, not our recurring revenue stream.
Project Spotlight: French Navy (La Marine Nationale)
The first major collaboration demonstrated the full potential of Marketing Mix Modeling for agencies. Working together, the teams constructed robust models integrating:
-
Media data across all channels
-
HR metrics (recruitment and awareness objectives)
-
External factors including economic indicators and competitive landscape
The engagement followed our proven phased, hands-on methodology with intensive educational components:
| Phase | Description |
| Phase 1: Collaborative Model Building | MASS Analytics specialists worked alongside INSIGN’s team, explaining methodological choices and transferring statistical knowledge in real-time. |
| Phase 2: Guided Autonomy | INSIGN analysts took increasing ownership of model updates and scenario planning, with expert review ensuring quality standards. |
| Phase 3: Full Independence | Ultimately, the agency now runs independent MMM analyses, integrating results directly into strategic client recommendations. |
We don’t believe in black boxes or hidden methodologies. Instead, every model we build together becomes yours to own, explain, and evolve.
“The solution was accessible, complete, and most importantly, it left us space. We weren’t just middlemen. We remained at the heart of the value chain, as advisors.” — Damien Schoennahl, Senior Partner, INSIGN
“We knew the main principles of MMM, but we had never put them into practice. Therefore, what we were looking for wasn’t just a tool, but real guidance. That’s exactly what we found with MASS Analytics.” — Arthur Gaudrie, Lead Product Manager, INSIGN
Results: From Tactical Service to Strategic Partner
The French Navy project established a new value delivery model for INSIGN that elevated every aspect of their client relationships:
Immediate Business Impact
| Outcome | What Changed |
| ROI Clarity | Campaign effects quantified from the first modeling cycle, with budget allocation optimized toward highest-impact levers |
| Stakeholder Elevation | Conversations expanded from Marketing Directors to HR Directors, CFOs, and General Management |
| Strategic Integration | MMM insights now inform broader business strategy, rather than just media plannin |
Capability Transformation
Technical Autonomy: INSIGN’s team now independently runs end-to-end Marketing Mix Modeling analyses using MassTer, thereby embedding MMM seamlessly into their OnePlatform ecosystem and client advisory workflows.
Market Differentiation: The agency stands apart by combining three rare capabilities: advanced data science, deep sector expertise, and strategic consulting acumen. Consequently, this intersection creates defensible competitive advantage.
In a commoditized agency market, MMM capability isn’t just a service line, it’s a moat. Thus, it protects your margins and elevates your brand.
“At first, MMM can look overwhelming and complex, maybe even intimidating for agencies like us and for clients. However, in reality, it isn’t. Thanks to MASS Analytics’ support, we were able to grow our skills at our own pace. Today, we’re proud to include MMM in our value proposition for all clients.” — Damien Schoennahl, Senior Partner, INSIGN
“What impressed us most was the bridge between tech and marketing. Your team masters the data, but you also speak the language of marketing in general, beyond just media mix. That’s rare, and it’s what makes the collaboration work so well.” — Arthur Gaudrie, Lead Product Manager, INSIGN
