What is Slice?

Slice is the leading technology & marketing platform made exclusively for local pizzerias, making it super easy to order delicious, authentic local pizza anywhere, anytime. We serve the $46 billion U.S. pizzeria market in two ways: by providing a pizza-centric mobile & web ordering experience for consumers, & by empowering local restaurants with the technology, tools, & marketing to grow their business, while helping them compete with Big Pizza.

Slice was born in 2010 & has quietly bootstrapped its way to building a network of more than 11,000 pizzerias nationwide. Ilir Sela, our founder & CEO, started the company as a passion project to help his friends & family in the pizza business, but he quickly saw a massive opportunity to champion these small businesses by bringing their bites to the masses. Ilir has since built an amazing team of operators, marketers, technologists, & investors all dedicated to making it easier for people to enjoy their favorite local pizza. Did you see we were recently Apples App of the Day?

Yes, we have a pizza philosophy

We believe pizza is more than food it's a slice of life. Across the world, pizza is made by people who care about craft, history, & culture. We created Slice to champion the small mom & pop pizzerias by connecting those proud makers with customers who are just as passionate about their pizza. We celebrate pizza as the ultimate shareable food that brings people together for more than just a bite.
