Founded in 2017 by Kateryna Sokolova and Arkadii Vartanov, NOOM was born from a shared vision to create interior objects that are both emotionally resonant and timeless in form. Drawing on decades of experience in industrial and interior design, the brand embodies a deep understanding of the creative process — from concept to execution. By blending traditional craftsmanship with modern technology and overseeing every stage of production, NOOM ensures every detail aligns with its design philosophy: thoughtful, honest, and emotionally engaging. NOOM believes in long-term value — not just in terms of quality and durability, but also in achieving a timeless aesthetic. Each piece is designed to be cherished and passed down, remaining relevant over time.
