Crowdsourcing for interior architecture Mon Ma?tre Carr? is the platform that enables as much individuals as professionals to call upon decorators or interior architects through remunerated contests. Using the crowdsourcing business model, we provide to our customers to realize contests between 3 decorators or architects on their projects. For a fixed price (based on the surface) and after a time previously set, our customer will choose between 3 different reports the one that fits the most to his tastes and attempts. On the other hand, our community is composed of architects and decorators looking for visibility, experiences, and especially customers. Together, we would revolutionize the architectural (and decoration) approach in France (and Europe) through our crowdsourcing platform easy to use, clear and ergonomic.
