The Operator app was developed by the co-founder of Uber and is designed to make online shopping easier than ever. CEO Robin Chan told TechCrunch writer Josh Constine the goal is to "unloack the 90% of commerce that's not on the Internet."
Refered to as a request network, the app uses human concierge to execute a variety of commercial customer requests. They hope to combine the best of real world and online shopping by offering expert personalized service that you might find in-store, but with the convenience and mobility enabled by the Internet. They are also flirting with the idea of integrating delivery in the future.
