What is Cyell?

Cyell is a Dutch brand in the bodyfashion sector, founded by Ella Wiersma and Cynthia Kooi. It presents itself as a swimwear specialist with around 30 years of experience.

History

In 2013 Cyell merged with fellow Dutch company Beach House to form a stronger bodyfashion group, with both brands remaining independent and sharing synergies in purchasing, export, logistics, production and service. The brand belongs to Zulk BV, a Dutch company that also owns the swimwear label Beachlife. In 2018 Zulk separated the management of the two labels to sharpen the positioning of each.

Products and positioning

Cyell's offer centres on:

  • Swimwear: bikini tops and briefs, swimsuits and tankinis
  • Beachwear such as dresses
  • Homewear
  • Suncare products sold alongside the swimwear

Distribution

Cyell sells through its own web shop and a network of retail points of sale, as well as department stores and sports retailers, including Breuninger.

Why it matters

Cyell is one of the established Dutch names in swimwear and bodywear, and its group structure shows how specialist labels consolidate to gain scale while keeping separate brand identities.
