What is WalkUp about?

We are on a mission to allow people to get a table anytime anywhere. Our first step; we’re getting rid of restaurant queue’s across London by allowing diners to queue remotely through our App. Next step is to allow other ways to getting access to tables of the best restaurants around the world.

We started in 2017 with a team of 3 with plans to change the way people access restaurants. Now we are in over 500 of the busiest restaurants across London and seat over 600,000 people each week. 

Tech Stack
