Per Diem

The AI operating system for restaurants

About

We deploy AI agents that act as a C-suite for cafés, bakeries, and restaurant franchises. Per Diem’s AI CTO automatically builds, deploys, and maintains branded mobile apps and web ordering, while our AI CMO and AI COO automate loyalty, marketing, and daily operations across first-party ordering and catering. Built on Square, 500+ brands including Oakberry, Shane's Rib Shack, and Crave Cookies use Per Diem to own their customers, increase lifetime value, and grow profitably.
