ByRotation

LiveInvested 2025

Fashion | Marketplace & Rental

ByRotation is the world's first social fashion rental app, redefining how we access and value clothing. Founded on the belief that style should be shared, not owned, ByRotation empowers people to rent, lend, and rotate their wardrobes — making fashion more circular, accessible, and community-driven.

Why I invested

Funnily enough, I once had a similar idea. When I discovered ByRotation, it felt like a full circle moment. The concept spoke to me immediately. But what truly convinced me was the founder — inspiring, forward thinking, and deeply committed to reshaping fashion in a meaningful way. Their mission, combining sustainability, fashion, and technology, closely aligns with my own. Supporting ByRotation wasn't just a financial decision. It felt like backing a better future.
