Unless you are a philatelist or have a strong tolerance for boredom, standing in post office lines is a pain. This is especially true if you have to do it over and over and over again for your job. ShipBob, a startup backed by Y Combinator, wants to help small business owners and online sellers with a service that not only takes items to the post office, but also handles packaging and tracking.

Before starting ShipBob, which is currently available in Chicago and plans to launch in San Francisco next, founders Dhruv Saxena and Divey Gulati ran a small e-commerce company called SnailMailPics, which meant they spent a lot of time preparing packages and waiting in the post office.
