The basics:

Sociavore, a digital hospitality and ecommerce platform for restaurants, was founded in 2018 by Thusenth Dhavaloganathan and Amina Gilani. With this service, you can quickly build a website for your restaurant from multiple available templates. The sites come complete with online food & drink ordering, merchandise sales integration, in-app messaging with guests, a contactless payment and pick-up system, and more.

From the BOH TipJar:

In addition to the flexible and user-friendly options built into Sociavore's platform, easy integrations with well-known platforms like Square and Resy are available. That way, you can get online shops and reservation books set up in seconds with preexisting accounts.

In their own words:

Sociavore pulls information automatically from dozens of data sources. Fully configurable guest tags, dietary restrictions, notes and integration with social media profiles including Facebook, Twitter, and LinkedIn let your team provide perfect hospitality every time. We make it easy to turn visitors into real guest covers - call, directions, messaging, and reservations are always one tap away.
