Case Study: Olivia & Kate

The Olivia & Kate story

Started by Janina as a boutique fashion store in the city of Haarlem, at some point loyal customers started asking for a way to order their products online. Then Steffen joined Janina to help drive online and profitable growth.

With a unique quality to price ratio within the market and a strong feeling for what their audience wants, the Olivia & Kate team has managed to grow rapidly. In the process, they took product design in-house and scaled up marketing and content production.

Today, Olivia & Kate is a household name in the Dutch fashion e-commerce and is actively exploring next geographical markets while staying true to their boutique heritage.

Challenges

Fashion comes with expensive stock levels and high returns to navigate
With clear product market fit, growing the top line in e-commerce is not too difficult. But doing it profitable and with cash conversion cycles that support the growth is way harder, especially in the fashion industry where stock levels are capital intensive and return rates can burn a hole in your performance.
Social and UGC advertising drive big net new reach, but also a risk of creeping CPA’s
The team at Olivia & Kate has structurally invested in high quality social content production and strong UGC partnerships that lead to big numbers in net new audience reach. But the risk of chasing vanity metrics while CPA’s creep up and margins get hollowed out by returns was holding back profitable growth.
Rapid growth means teams need to be aligned daily to make informed decisions
As the product design and marketing teams were growing fast, keeping everyone aligned on goals and performance became increasingly difficult. And with most team members not being comfortable browsing through several apps and spreadsheets, Olivia & Kate needed an easy to use performance interface that contains both marketing and sales insights.
NEW CHALLENGE: Navigating agentic usage across different users and apps
With Claude quickly gaining momentum and internal & external team members building their own analysis, automated workflows and apps. Managing the data accuracy and access underneath these new interfaces is quickly becoming a major challenge

The solution

Through the Eyk platform & community, the Olivia & Kate team has quickly gained daily insights into product performance, profitability, channel attribution and overall Cost per Acquisition (CPA) and Marketing Efficiency Ratio (MER).

Being able to start every day and meeting with these insights at hand allows for better and quicker decision making on their way to more profitable growth.

‍By applying Eyk’s data-driven + views attribution model, the team has also gained a deeper understanding of which ads and campaigns drive profitability and which have platform claims attached to that actually hurt the progress. Marketing budgets are deployed more informed, resulting in higher ROI across channels.

Since Eyk runs natively on a Google Bigquery data warehouse that Olivia & Kate owns, and with the MCP connector and upcoming apps functionality turning Eyk into an AI command center, the team is able to innovate with AI agents on topics like rolling cash forecasts, LTV cohort analyses and supplier apps, while staying completely in control of the numbers and data access.

Eyk has already given us the strategic and tactical insights to keep our growth controlled and profitable. And with everything coming up around agentic AI, I see Eyk as a fundamental platform for the future of our brand.

"It is exactly the type of entrepreneurs and brands like Steffen and Olivia & Kate that fit well with how we approach e-commerce data at Eyk" says Alain. Adding: "High growth, with complex customer journeys and profit calculations and a drive to do a little bit better every day, this combination gets everyons on the Eyk team going to push hard and drive value for Steffen and his team."

Steffen says: "
He adds: "The new profit/margin feature will help us dig even deeper into ROI per ad, campaign and channel and I also look forward to seeing more and more AI search engine traffic come up in our attribution and experimenting with forecasting through Google's Gemini, which is way easier now that we have all our data stored and structured in BigQuery through Eyk."
