Global hospitality software business Guestline announces the appointment of Andrew Metcalfe to the new role of chief technology officer and a commitment to double its UK-based development team. The senior appointment for the business, and ambitious growth plans, come as Guestline expands further to support a more diverse range of new clients, including large hotel groups, universities, a wide selection of serviced accommodation providers and a growing number of international hotels. Metcalfe will be responsible for ensuring the business accelerates its programme of innovation as one of the industry's premier technology driving forces, and will lead all product development, infrastructure, technical support and IT functions. Previously, Metcalfe headed up London based engineering at OpenTable, working for the company for over six years in roles including head of search engineering, and head of international engineering. He joins Guestline from Ve Interactive, an e-commerce technology company, where he held the roles of development director and most recently chief technology officer, overseeing teams in the UK, Spain, Romania and France.
