Smartphones have become an integral component of lifestyles worldwide, acting as mobile computers capable of life organization. They remain the most quickly cycled consumer electronic, owned for no more than 3 years on average. Individuals continue to upgrade their smartphones quickly, stemming from the desire for more power and better features. In 2016, there were 1.15 billion smartphone upgrades, resulting in a growing used smartphone market valued at \$18 billion. Individuals continue to invest time and effort to sell their smartphone, receiving payment of less than market value. In regards to value-minded users with solidified schedules, I created Trusted Trade-in. This startup provides the bustling middle class with the ability to upgrade their smartphone in an efficient and valuable manner. Compared to current solutions, Trusted Trade-in offers an all-in-one upgrade system. The creation of this startup involved the complete creation of a business model in addition to the coding of a responsive website. An online-based business, customers will be able to visit the Trusted Trade-in website and be given the options to trade-in or trade-up. Competing against Craigslist, eBay and Verizon, Trusted Trade-in features a combined smartphone resale and upgrade process. If the decision is made to trade-in, the customer will be quoted for their current smartphone according to specific physical criteria. The trade-up option will request the same information from the customer and allow them to select a new model for their upgrade. This exciting and innovative marketplace will completely transform the way people upgrade their smartphones through financial and time-based savings.
