Lillydoo's Story
In 2014, Sven and Gerald left the corporate world with a clear mission: to create the most skin-friendly diaper. What started in Sven’s living room soon became LILLYDOO—a brand redefining baby care.
After 12 months of development, LILLYDOO launched its first diaper in 2016. Rapid growth followed, expanding to Germany, Austria, Switzerland, France, and the Netherlands in 2017, with Spain and Italy soon after. By 2018, LILLYDOO was available not just online but also in local drugstores.
In 2019, the company strengthened its roots, packing every diaper with care at its Berlin-based logistics center. A year later, sustainability took center stage with LILLYDOO green, bringing the vision of an eco-friendly diaper closer to reality.
By 2022, LILLYDOO had delivered 500 million diapers to families across Europe, proving that high-quality, skin-friendly, and sustainable baby care can go hand in hand.
Scaling Data-Driven Targeting
The Innkeepr Moment
LILLYDOO integrated Innkeepr’s AI-driven predictive audiences to enhance its Meta ad targeting strategy. By leveraging first-party subscription data, the company was able to identify and reach high-intent users more effectively, ensuring that ad spend was allocated toward customers most likely to subscribe.
"With ASC restrictions making traditional targeting less effective, we knew we needed a solution that could work with first-party data to refine our approach. Innkeepr’s predictive audiences gave us exactly that," says Maximilian Weber, Senior Performance Manager at LILLYDOO.
Innkeepr’s AI analyzed LILLYDOO’s existing subscriber base, identifying key patterns and behaviors that indicated purchase intent. This allowed the company to create high-performing audience segments and optimize its Meta advertising strategy across all countries.
Measurable Impact on Growth
The results of integrating Innkeepr were significant:
A 11.7% reduction in Cost per Acquisition.
A 56.8% increase in Meta ad spend (YoY).
More precise targeting, reducing wasted spend on low-intent users and improving overall conversion rates.
How Lillydoo Uses Innkeepr
With Innkeepr’s AI-driven audiences, LILLYDOO has transformed how it approaches paid marketing. By moving beyond traditional ASC campaigns and fully embracing predictive capabilities, the company has future-proofed its strategy against evolving changes in the ad targeting landscape.
LILLYDOO continues to refine its approach, leveraging AI to reach their new customer segments more effectively while sustaining growth in the competitive baby care market. As the landscape shifts, the company is well-equipped to stay ahead, ensuring their social channels are optimized for maximum impact.
