Welcome to Shackle, the name you ask? Ernest Shackleton was Ireland’s most famous explorer who sailed into unknown territories for adventure. A bit like integrating with hotel systems. Ok we joke, they aren’t that bad. 

For hotel guests, we simply allow them to skip to the good bit. No more long queues checking in, no more lost plastic key cards (that’s bad for the environment, Go Greta) and no more ordering room service by fax….sorry, we mean calling on the room phone. 

For hotels, you finally have an app that works, that your guests actually want and that enhances the guest stay. Yes, it reduces costs, gives you lots of data on your guests and if you work closely with us, starts to drive guests to book directly with you instead of you know who (Big B). 

We want to be your partner, not just your hotel app. We are fun, we love travel and are obsessed with giving guests the best hotel experience, if that sounds like a good fit, let's connect.
