How our Journey Began

Our story began in 1999 with two individual companies on two separate continents with trailblazing entrepreneurs at their helms. Both shared similar goals ─ to streamline restaurant and hotel processes through intelligent technology. Both grew exponentially and became well-recognized brands in the technology sector — Fourth and HotSchedules.

Then in July 2019, these two companies merged to fulfill one shared goal as Fourth. Today, Fourth is a leader in data-driven workforce and inventory technology for the retail, restaurant, and hospitality sectors. With over 20 years of expertise in data and analytics, Fourth Intelligence is trusted by over 15,000 customers across 100,000 sites globally with 2.5 million users.

And as we continue our founders’ legacy, we are proud to advance the Fourth Industrial Revolution ─ the momentous change in our environment where disruptive technologies and trends will revolutionize how we live, work, and relate to one another. With the Fourth Intelligence Platform, we aim to transform how our customers conquer the day in the increasingly dynamic-paced environment in which they operate.
