Founded in 2015 with offices in London – UK, London – Ontario, Atlanta and Singapore, we have many thousands of users of our B2B platform across the globe. Brands using Tyk range from Lotte, Bell, T Mobile, to RBS, Capital One and Vinci.

Tyk is on a mission to connect every system in the world. We’ve started by building an API Management platform.

We offer unlimited paid holidays and remote working from anywhere in the world, for everyone, Why? Tyk was founded on the principle of offering flexibility and autonomy to our employees, we believe this allows our employees to achieve their best results. It also means we can build the best possible team, location and working hours are no barrier.
