1. Executive Summary

Client: Endresz | Industry: Women’s Fashion (High-End Designer Brand)

Challenge

Endresz, a high-end women’s fashion brand, wanted to scale partnerships with independent designer boutiques across Europe. The challenge: this ICP is extremely niche and hard to qualify. Many boutiques don’t list themselves on LinkedIn or major databases, and not all shops fit Endresz’s strict criteria (premium, multi-brand, high-end positioning).

Solution

Closedin built a multi-market outbound system across the Netherlands, France, Poland, London, and select global markets. We combined Apollo lookalike lists, Clay filters, Deepseek enrichment, and Apollo keyword targeting to refine boutique lead lists. Campaigns were personalized in local languages, with messaging crafted to resonate with boutique owners.

Key Results

$128,025+ in boutique pipeline created within 6 months.

2. About the Client

Endresz is a Dutch women’s fashion brand specializing in timeless, high-quality designs produced in small batches. Their mission is to bring sustainable elegance to carefully curated boutiques worldwide.

Endresz partners only with stores that share their aesthetic and values, making finding and qualifying the right boutique buyers critical to their growth strategy.

3. The Challenge

Before working with Closedin, Endresz faced three major challenges:

• Niche ICP – qualifying the right boutiques was difficult. Many shops were either too small or not aligned with Endresz’s premium positioning.
• No reliable outbound system – initial outreach generated replies, but many leads weren’t valuable (general interest, wrong fit, or too small-scale).
