Klook is a travel activities (tours and attractions) platform. It allows travelers to book tours, diving activities, park visits, even train tickets, and more. It mostly targets travel in Asia.

And it connects with activity suppliers either via a SaaS interface (extranet) or an API. To get the idea, you can read how OTA back office works.
