The company started as a result of trying to solve a simple problem - how to make a beautiful space to store what’s on your mind? A place for all the ideas, dreams, sketches, or thoughts – everything endless. Dheeraj, previously a management consultant, and Aditya, an automobile engineer, always chose a notebook to be the first place they put their thoughts in. Driven by a mutual passion for design, and building products, they chose to leave their corporate careers and write a new page in their life. Build and design stationery, with the user at the heart of it. We hope you enjoy the product as much as we enjoyed making them!
