The guest experience geeks

We believe that technology can transform the guest experiences of the future. And we’d like yours to lead the way.

Julie Grieve ran a luxury serviced apartment business in Edinburgh called Lateral City prior to founding Information Apps. When setting them up, she created a guest information book, which took a significant amount of time and money and yet as soon as it was printed and in the apartments, she realised it was out of date as a local restaurant had closed down.

Furthermore, one of the beautiful locations in the group was proving a little tricky for guests to find, as its entrance was set back from the main street. No matter how detailed the instructions were, guests often said things like “Oh, I didn’t notice that email”, or “I couldn’t find your message and I didn’t want to use my data”.

At the same time, she had re-written instructions for the boiler in her holiday home because guests found it difficult to operate. She wondered if there was a way she could make a video of how to use it and if she made it where would she store it and what might that costs?

This led her to look for an innovative way to help her guests have the information they needed at their fingertips, and Criton, the app builder for the hospitality industry, was born.
