About Checkmate Checkmate is a restaurant technology solution provider that has continually evolved over time. We started in 2017 by integrating 3rd party platforms to the POS systems of restaurants. At that time, there were multiple 3rd party platforms like GrubHub, UberEats, DoorDash, Postmates, Caviar, and even Amazon! This was the photograph that started it all! We have since then continually evolved to add multiple products to our portfolio, the primary ones being first party ordering solutions like web and app ordering, kiosks and catering. We have now recently moved into three new exciting products: Digital Menu Boards, Phone Ordering AI and Drive thru AI. We form a very core part of the restaurant technology ecosystem, and are continually adding more and more digital solutions for the restaurant brands to increase their sales. Our revolutionary enterprise menu management system, Everyware, truly unlocks the potential of menus and how it can be customized for each individual digital channel. As you can see, this is a company that continually evolves and adapts and today we are powering digital ordering solutions for some of the largest brands in the world. We have been called the "north star of vendors" as we truly believe that technology is just a method by which we service the customers, it does not form the entirety of it. Service is a big component of what we provide to our customers, which is inherently believed by every single team member here. We are doing a lot of exciting things, including application of AI in our products and systems, using experimentation at scale to determine what works for our clients and ML to analyze and productize the massive amount of data we have. Each individual here makes a difference and has a valuable contribution. Key traits here are ownership and drive. Join us if you think you have them.
