About Finnish Design Shop
Finnish Design Shop — one of the largest online stores for Nordic design — set out to expand its international reach and deliver a localized shopping experience that felt as effortless abroad as it did at home.
They identified personalization and merchandising as growth opportunities. After comparing different service providers in the domain, they selected Constructor’s solutions, opting to use A/B testing to validate their effectiveness.
Finnish Design Shop integrated Constructor’s Search, Browse, and Recommendations features into its online store. Customers’ perceived page load speeds and search engine visibility were finely optimized. As a result, Finnish Design Shop saw measurable lifts in conversion rate, revenue per visitor (RPV), and add-to-cart behavior within a few weeks of A/B testing.
The team credited Constructor’s data-driven Proof Schedule and, later, the Continuous Optimization Program (COP) with helping them build trust in the data, react more quickly to shopper intent, and establish a scalable foundation for long-term global growth.

The Challenge
A Growing Brand, a Static Discovery Experience
For the last 21 years, Finnish Design Shop has curated the finest Nordic furniture and home décor, serving customers in over 100 countries. The company’s international expansion, alongside its continuously growing product assortment, presented new challenges that required a new approach to ensure future growth, scalability, and a seamless product discovery experience for its users.
The Finnish Design Shop team had identified merchandising, localization, and scalability as key areas and processes they wanted to improve. They needed a new technical solution that could handle their existing challenges more efficiently, particularly in supporting multiple languages, country-based requirements and regulations, and other international retail-related complexities that were previously difficult and time-consuming to manage.
They simultaneously had a business initiative aimed at improving their conversion rates and creating more seamless and personalized shopping experiences for their users. They had identified dynamic, contextual personalization as a required capability for the new platform that would help them achieve these goals and transform their previously static site experience into a dynamic, highly personalized product discovery journey that adapts to user behavior and trends, while ensuring the site is optimized for their business needs and KPIs.

The Proof Schedule
How Verified Shopper Data Uncovered Blind Spots
For Finnish Design Shop, it was the Proof Schedule that sealed the deal.
During this data-driven, low-risk pilot, data scientists from both teams analyzed Finnish Design Shop’s search logs, merchandising gaps, and real shopper behavior. This revealed promising potential in ranking optimization and uncovered missed revenue opportunities.
Once Constructor’s algorithms took behavior and contextual awareness into consideration, rankings reflected both precise and attractive results, greatly improving the chances users will convert on an item.

The Results
Unlocking Measurable Growth and New Merchandising Agility
Within several weeks of launching Constructor on their website after doing the Proof Schedule, Constructor’s AI-first Search, Browse, and Recommendations products delivered strong initial gains in conversion rate, RPV, and average purchase revenue.
It wasn’t all about the numbers. Throughout the whole Proof Schedule process, Lindqvist reported that what stood out was how collaborative and transparent everything felt. The Proof Schedule not only validated Constructor’s model, but it also established a foundation of trust between both teams, enabling data-driven decisions from day one.
"What helped us make the investment was the Proof Schedule itself. It was very data-driven. You were able to show us where we had issues, where you could make improvements, and tell a clear story around the data and the kind of sales lift you could generate. … I found the Proof Schedule to be a great starting point to get to know each other and build trust in both the tool and your team."

Continuous Optimization
Fine-Tuning Algorithms for Smarter, Revenue-Driving Results
Since the initial uplifts, Constructor has been able to produce additional positive results for Finnish Design Shop, thanks to the Continuous Optimization Program (COP).
This program is a core component of all Constructor partnerships and is run by our Data Science teams. In the program, we help clients use verified clickstream data and fresh insights to continually refine their algorithms and drive results for both the business and its customers.
Thanks to COP, Finnish Design Shop was able to undergo even more revenue-boosting initiatives, such as further optimizing the algorithm to re-rank results by geography, layering behavioral signals like operating system and browsing history, and using local purchase data to train regional reranker models.
These extra data-driven personalization approaches have paid off.
In selected highly competitive regions, Finnish Design Shop achieved measurable increases in browse revenue (+26%) and add-to-cart-to-purchase rate (+45%). The furniture and home decor brand secured a 13% revenue uplift on their Finnish storefront, thanks to a new Search reranker model that was trained with their regional user behavioral data for Finland.
Alongside these regional optimizations, Finnish Design Shop has continued to advance its personalization strategy, experimenting across the entire shopping journey.
Overall, the Constructor solution unlocked the ability to experiment quickly — i.e., to A/B test merchandising changes, react to trending products, and optimize for regional intent.

“What we were really happy about were the new capabilities that let us step in and react quickly. We can now modify product listings to display only in-stock products and hide those that are out of stock. And of course, we’ve enjoyed seeing how the algorithm lifts relevant and trending products. It’s far more reactive to what people are actually engaging with, rather than delivering a static experience. … It’s given us capabilities to deliver an individual shopping experience to each customer.”
