Seclo is an iPhone application developed by Seclo B.V., offering a unique online marketplace for upcycled fashion. The platform focuses on high-quality second-hand and new clothing made from waste streams. Emphasizing the importance of local businesses uniting against fast fashion, Seclo aims to make high-quality upcycled fashion more accessible.

One of the standout features of Seclo is its support for businesses to sell their products, a feature not commonly found on other platforms where only individuals can sell. Additionally, the platform boasts a wide range of upcycled fashion, offering a larger reach compared to individual accounts on platforms like Instagram. Buyers are provided with seller verification for added security, and Seclo functions as a dynamic social media platform, allowing users to share not only photos but also videos and stories. Building a community around brands is encouraged, making the shopping experience more engaging and interactive.
