The company employs a mix of robots and humans to create and deliver one of America’s favorite foods.

Zume Pizza, a tech start-up that uses robots to make pizza, has raised nearly $50 million. Cofounder and co-CEO Julia Collins previously told CNBC she hopes to service the entire Bay Area from its Mountain View, California, facility by the end of 2018.

The Mountain View, California, company has raised about $48 million, just $2 million shy of its $50 million goal, according to a filing with the Securities and Exchange Commission. Last December, it raised $23 million at a $50 million post-money valuation from a round of series A funding, according to Pitchbook. Zume Pizza employs a mix of robots and humans to create and deliver one of America’s favorite foods. Robots perform highly repetitive tasks like squirting and spreading tomato sauce and placing pizzas in ovens. Humans help with food preparation, recipe development, taste tests and work to improve their pizzas based on customer feedback, cofounder and co-CEO Julia Collins had previously told CNBC.

Zume sold its first pizza on April 1, 2016. Collins hopes to service the entire Bay Area from its one main facility by the end of 2018.

Not everyone likes the idea of robots replacing people. Bodega, a start-up that creates an automated system to mimic a convenience store, received fierce backlash last month. Its founders later apologized to offended city dwellers.

The company says it is dedicated to quality, tasty food. According to Zume, their pizza dough is fermented for 18-24 hours, using flour, fresh yeast, filtered water, salt and extra virgin olive oil. The long fermentation is supposed to make the dough easier to digest and more nutritious than commercial pizza dough. The flours are non-GMO and never bleached or bromated.

The produce is sourced from local farms, which means that it arrives days after the harvest at the peak of ripeness; the artisan cured meats are crafted by hand and made using only naturally occurring nitrites and nitrates whenever possible. The company website further adds that the packaging is made from 100 percent sugarcane fiber and every component of the box, including the sticker is totally biodegradable and compostable.
