Quindi Research provides custom research and analyst services for organisations throughout the smart energy and wireless communications sectors. At the heart of what we do is understanding the impact of technology change on the world around us, and our research and publications help software vendors, equipment manufacturers, network operators, service providers and regulators identify and exploit the opportunities from the emergence of new technologies. Quindi Research is based in Cambridge, UK. In 2015, we launched Prepaid Energy Hub (http://prepaidenergyhub.com/), a free-to-use online resource for all those interested in the growing phenomenon of pay-as-you-go utility services. The website provides in-depth coverage of global trends and developments in energy prepayment during the transition to smart metering, including feature-length analysis of industry hot topics, articles on company and product news, and case studies of utility prepayment programs.
