Short overview of Wavemaker

Through continuous innovation, the agency provides expert consulting and tailored solutions, helping brands navigate an ever-evolving landscape.

Challenge: Scaling Performance to Meet Ambitious Targets

The Stroili E-commerce team was pushing for growth, but scaling performance while maintaining efficiency in a very dynamic market proved challenging. Efficiently optimising the budget was difficult and time-consuming.

To navigate this complex landscape, Stroili collaborated with Wavemaker, their trusted media agency in Italy, to optimize their marketing performance. Together, they explored new strategies and tools to enhance efficiency and profitability.

Key Challenges:

1. Data-rich, but lacking actionable insights – Stroili already implemented an attribution system, but scaling up the media investment remained a challenge across so many campaigns.
2. Advertising portfolio saturation – With the competitive market situation and highly saturated existing setup the team struggled to unlock new growth opportunities and further optimize their existing portfolio.
3. Shifting performance goals – Alternating goal setting between ROAS-driven scaling and revenue-focused efficiency required constant adjustments from the teams.

Despite their best efforts, Anastasiya Auramenka, Digital Marketing Manager at Stroili, saw untapped potential in their campaigns. She knew that an innovative AI-driven solution could provide the breakthrough they needed to scale performance sustainably.

This is where Nexoya came into play. 

AI-Powered Transformation: From Gut Feel to Data-Driven Precision

Seamless Onboarding & Adoption

Stroili’s E-commerce team, together with Wavemaker, launched a pilot with Nexoya to explore how AI-powered optimization could elevate their performance marketing.

From day one, the onboarding was smooth and efficient. With support from a dedicated Customer Success Manager, Anastasiya and her team quickly integrated Nexoya into their existing workflow. Within three weeks, five marketing channels and the respective attribution tool were fully connected, giving Stroili and Wavemaker a centralized view of their data for smarter decision-making.

Beyond ongoing support, Stroili also joined a special AI session with Nexoya’s team, gaining insights into AI optimization, best practices, and continuous improvement strategies.

Breaking Through Saturation & Unlocking Growth

Reallocating budgets across the channels wasn’t enough – Stroili needed a smarter way to scale. Nexoya’s AI identified saturation across hundreds of campaigns early and provided actionable recommendations to diversify campaigns.

With guidance from Nexoya’s team, Stroili:

• Redesigned campaign structures to remove inefficiencies and increase impact.
• Used predictive modeling to simulate budget scenarios and revenue impact before investing.
• Optimized cross-channel performance automatically, adjusting weekly based on AI insights.

Once the setup was optimized, AI-powered automation unlocked new growth potential.

The New Optimization Process: AI-Driven, Continuous, and Scalable

With Nexoya, Anastasiya and her team embraced a fully data-driven approach to marketing optimization, shifting from manual budget decisions to AI-powered, automated predictive planning.

Anastasiya was particularly excited about this transformation, as Nexoya introduced automation and predictive analytics to their process. What used to take hours of manual analysis and guesswork was now streamlined and backed by data and actionable AI-driven insights.

The entire process became fully automated and driven by data, transforming the way the Stroili team approached performance marketing.

The Optimization Process: 

1. Predictive Scenario Simulations

• Stroili’s team used Nexoya’s scenario simulation feature to forecast their ROAS and revenue.
• By simulating different budget scenarios, the team eliminated guesswork and ensured the most effective strategy for each goal.

2. Weekly AI-Driven Optimizations

• Nexoya’s algorithm continuously analyzed all incoming data to provide weekly optimization recommendations across all channels and campaigns. 
• The platform provided a cross channel and campaign proposal which the team was able to review and accept with one click. The budget got reallocated automatically. 

3. Continuous Growth & Scalability

• Nexoya helped Stroili maintain the right balance between conversion-focused campaigns and brand awareness efforts, ensuring a sustainable marketing funnel.

4. Monitoring & Validation

• Once the optimization was complete, the Stroili team could continuously monitor and validate the results using the prediction accuracy score. This metric allowed them to assess how precise Nexoya’s predictions were by comparing the predicted outcomes with the actual results.

“It was incredible to see how much potential we could unlock from our data! Nexoya provided us with a fresh perspective, allowing us to refine our processes and scale in a more sustainable way. The combination of automation and AI-driven insights not only enhanced our performance but also made decision-making significantly easier and faster.”
