Scottish travel technology start-up Criton Apps has secured a £5m investment as it gears up for overseas expansion.

Criton has developed a self-build guest app service to hotels and serviced apartments. The software combines guest-facing information such as destination guides, guest and property management information.

The funding, which came from an anonymous private investor, will allow Criton to grow staff numbers from its current six to more than 30 in the next two years.

The Edinburgh-based firm also plans to open sales offices in London and the Middle East early next year.

Julie Grieve, founder and chief executive, said the company has "achieved a lot" in the first 12 months, both in customer sign-ups and awareness.

"Our app-builder offers independent hotels a guest facing technology which rivals anything offered by chains such as Hilton and Marriott and we are making an impact," she said.

"This is a sector, however, where it is important to move fast and this investment will allow us to take Criton to the next level with more staff and an international sales team

“We believe the future of travel and hospitality tech is on the guest’s own device, where they can use their own phone or tablet to check-in, access their room and operate in-room appliances using the power of the Internet of Things."
