Dedicated to blending modernist aesthetics with traditional Portuguese craftsmanship, MO-OW was founded by architects Ângela Frias and Gonçalo Dias in Matosinhos in 2010. Frias (1977) and Dias (1977) are both trained architects—the former graduated from ESAP in 2004; the later from University Lusiada of Porto in 2002—which carries into their simple, minimalistic, functional chairs, tables, and storage pieces.

The duo joined forces in 2004, when they launched their architectural studio A2Garquitectura for residential, commercial, and exhibition projects. Each piece handcrafted in fine wood using time-honor artisanal techniques, MO-OW furniture has been exhibited at the Serralves Museum of Contemporary Art of Porto; the BLOOOM Art Fair Cologne 2012; Clerkenwell Design Week London 2013; and Beijing Design Week 2014.
