...new light, fresh angles

Originally founded as Sandford Technology in 2002 Refractiv has a strong pedigree in online products and services, security, web and software development. Refractiv is a UK-based private company with offices in the Leeds area and Birmingham. Most of our customers are in the UK although we work with international businesses and have customers in Canada and Australia. In 2006 we acquired Leap Frog, an award-winning web design and development business; this acquisition extended our market for custom websites, particularly in the public sector, and also strengthened the creative side of the business. Cloud Solutions Business is being rapidly transformed into a predominantly digital landscape, with enterprises large and small transacting through Cloud Services, advanced websites and hosted applications. Clients, prospects, suppliers and staff will expect and need to interact with businesses in new, sophisticated ways. This digital environment is the hub of the business, and increasingly its primary public presence. Cloud services enable businesses to drastically reduce their IT infrastructure while increasing their online presence and interactivity. Staff can work more flexible hours, from any location, using simpler and often smaller devices. Refractiv is well-placed to provide the development, integration and support services to deliver this future.
