Sara Murray - Great female technology entrepreneurs

Sara Murray runs buddi, which provides personal GPS tracking devices and software to vulnerable people and their carers. She started it just over 4 years ago.

Sara started out in management consulting in a US company and then did a short spell in the City. She founded her first business at 22 in the pharmaceutical arena, providing software and consulting on sales forces, and later became a non-exec director of Schering Health Care. That business morphed into Ninah, which provided marketing advice and software to major brand owners, allowing them to see the P&L results of changing marketing investments. She sold the business to part of Publicis Groupe and joined the Board of ZenithOptimedia. During that time, she founded an online insurance comparison website, which was sold to Admiral Insurance Group - Confused.com.
