Zume Pizza uses a combination of robots, artificial intelligence (AI), and GPS in its food trucks to deliver pizzas to customers houses just as the pizza is finished baking. Pizzas are actually prepared and baked in the Zume pizza truck by an employee assisted by robots. Zume Pizza started operations in April 2016 and is currently selling about 250 pizzas per day.

The pizza delivery process starts with a customer using Zume Pizzas app to order pizza. The pizza combinations offered by Zume have been derived by analyzing customer data to offer several popular options. These preset combination recipes are programmed into Zumes computers, so that its robots can build and bake the pizzas efficiently.

All pizza preparation and baking happens in the Zume pizza truck. Once the customer orders a pizza, a worker in the Zume food truck will toss the dough, cut the vegetables, and put on toppings. A robot will put on the pizza sauce. Each Zume pizza truck has 56 pizza ovens, which are each individually connected to the order system and the trucks GPS. A robot will put the pizza into the designated oven exactly four minutes before the truck reaches the customers house. A worker will pull out the pizza when it is finished and place it into the cutter, where a robot will cut the pizza. The pizza is boxed and the pizza is delivered to the customers door, all within a few minutes of finishing baking. Eventually, Zumes owners hope to use a robot to remove pizzas from the oven as well.
