What is InterioApp?

Our Journey (Vision)

Born from the heart of the curtain and blind industry, InterioApp has its roots in a family business that needed a simpler way to operate. After many years in the industry, we discovered that our challenges were not unique but shared by many. From this realization and with the support of our suppliers, we extended our self-developed curtain calculator to other businesses across Europe, transforming a personal solution into a global tool.

Our Quest (Mission)

Our mission at InterioApp is to aid small retailers in achieving business success and profitability. We've walked a mile in their shoes, understanding the hurdles they face firsthand. Now, we're equipped with the knowledge and tools to help them overcome these obstacles. Our quest is to share these insights and solutions with the wider world, bolstering businesses one curtain calculator at a time.

Our Ethos (Values)

At InterioApp, we create value by offering the right tools and unparalleled support in an IT landscape where such service can be scarce. Our firsthand experience with the European, Canadian, UK, and New Zealand markets means our algorithms cater to the specific needs of these locales. We believe in fostering growth, innovation, and efficiency, which is why we've also launched an online store for businesses to easily sell curtains and blinds. Our ethos is shaped by the belief that providing the right tools and knowledge can transform the way businesses operate, allowing them to thrive in a competitive market.

InterioApp (Curtains Calculator) is a comprehensive online tool designed to simplify the process of calculating accurate quotes and providing detailed product information to customers. Our app is tailored specifically for curtain retailers, distributors, and designers, offering a range of features to make your online business a success.
