About us

We help restaurants through our platform that aggregates and uses delivery data to improve restaurant management on Delivery Platforms.

We provide competitors data that restaurants don’t have, machine learning backed recommendations for restaurants to improve their delivery offering (pricing, promos, menu composition..) and AI-powered features, like delivery menu pictures / dish description creation.

With pleez, restaurants have their delivery channels on auto-pilot. Now, they just need to focus on cooking.
