Shipping costs are at an all-time high with rising oil prices and inflation. While online retailers are extremely sensitive to shipping costs, they are also looking for ways to keep up with accelerating consumer demand for faster shipping, while differentiating themselves from competitors. Carry provides same-day delivery for e-commerce retailers, below the cost of ground shipping. We eliminate the need for a physical sortation center by building software to emulate a sortation center inside delivery vans. Mobile re-distribution enables gig drivers to perform efficient same-day delivery resulting in profitable, efficient, scalable e-commerce delivery. Our model allows us to ship faster and decreasing shipping costs, while having a positive impact on the environment by shortening the total distance a package has to travel in order to reach the customer.
