Since the spread of COVID-19, the Coronavirus has been devastating to smaller designers who are up and coming. Based on this issue, we will create an e-commerce mobile app -- Co-N, which means collaborate and connect with new brands. The app allows satisfactory startup designer brands to register our services, and they can post and sell their products through it. Our customers can choose their preferred styles to shop, which creates exposure for startup brands and a seamless user experience for customers to acquire new and innovative designs. The growth of brands will allow us to expand brand collaborations, stay on the cutting edge of app development, and prepare pop-up stores once COVID-19 has subsided.
