Case Study: Ninja
Scaling Across Europe and Extending into Walmart with a Unified Marketplace System
Overview
Ninja is a globally recognized brand in kitchen appliances, known for strong product innovation and strong consumer demand.
As Ninja expanded into Europe, the challenge was not demand generation.
It was coordinating marketplace performance across regions and channels.
Eva partnered with Ninja to build a unified marketplace growth system centered on Amazon, supported by paid media and data-driven decision making.
Once the system was established, the same framework was extended into Walmart US as a marketplace expansion layer.
The Situation
-
Core issue: Ninja entered European markets with strong
brand equity and demand, but faced structural complexity
- Fragmented Amazon execution across countries
- Disconnected performance between marketplaces and paid media
- Rising advertising costs without unified optimization
- Limited visibility into profitability at SKU level
- No coordinated strategy across regions
The challenge was coordination at scale.
- Amazon performance varied by region without shared intelligence
- Advertising lacked unified allocation logic
- DSP and Sponsored Ads were not fully integrated
- Inventory, pricing, and ranking strategies were disconnected
This created inefficiencies and limited scalable growth.
Eva implemented a unified marketplace intelligence system across Europe.
The Eva Approach
Amazon Intelligence + DSP Activation
- Full-funnel Amazon advertising strategy
- Sponsored Ads and DSP integration
- Market-specific keyword and ranking strategies
- Listing and conversion optimization by region
Result: stronger demand capture and improved ranking velocity
Paid Media Orchestration
- Cross-channel budget allocation based on performance
- Creative and audience testing across markets
- Alignment between paid media and Amazon performance
Result: improved efficiency and scalable acquisition
Unified Product Intelligence Layer
- Centralized visibility into revenue, spend, and profitability
- SKU-level performance tracking across markets
- Real-time data-driven decision making
Result: faster optimization and more effective capital allocation
Execution
Faster SKU activation compared to new marketplace launches
Incremental revenue without additional demand creation cost
Improved total marketplace coverage in the US
Efficient scaling through reuse of Amazon intelligence
The Outcome
Growth was no longer fragmented by region.
It became coordinated and scalable across markets and platforms.
What Changed
Before Eva
- Country-by-country execution
- Limited coordination across Amazon markets
- Inefficient advertising allocation
- Fragmented data and delayed insights
After Eva
- One unified marketplace system centered on Amazon
- Real-time optimization across regions
- Integrated advertising and ranking strategy
- Scalable and controlled international growth
- Seamless expansion into Walmart without rebuilding infrastructure
“Our challenge in Europe was not demand. It was coordination across markets, channels, and data. Each region was operating, but not in sync.
Eva brought structure to our Amazon strategy and connected performance across markets, which immediately improved efficiency and visibility. We were able to make faster decisions, allocate budgets more effectively, and scale with greater control.
What made the difference was not just execution, but the system behind it. Once that system was in place, extending into Walmart became a natural next step. We did not need to rebuild anything. The same intelligence, assets, and approach carried over, allowing us to activate Walmart quickly and efficiently.
Eva helped us move from fragmented execution to a coordinated, scalable marketplace strategy.”

Strategic Insight
Marketplace expansion does not fail due to lack of demand.
It fails due to lack of coordination.
Once Amazon performance is structured, expansion into Walmart becomes execution, not experimentation.
When marketplaces operate independently:
- Spend increases
- Efficiency declines
- Growth becomes inconsistent
When marketplace signals are unified:
- Ranking strengthens across regions
- Advertising becomes more efficient
- Expansion becomes predictable
Amazon growth is not ad spend
It is a system where ranking, demand generation, and conversion work together to scale profitably
