About Connexin

Connexin is a digital infrastructure company focused on building and operating smart city technologies. Founded in Hull in 2006 by Furqan Alamgir and Alex Yeung, the company originated while Alamgir was studying medicine at Imperial College London. His background as a surgical registrar in the NHS fostered a belief in technology's potential to transform public services, particularly healthcare. This perspective shaped the company's mission to bridge the digital and real worlds to improve quality of life.

The firm operates by developing and managing network infrastructure to support the Internet of Things (IoT), enabling smarter, more efficient services for its clients. Its customer base primarily consists of public sector organizations, such as city councils, and utility companies. For these clients, Connexin deploys end-to-end smart solutions for services like water metering, waste management, lighting, and traffic monitoring. Revenue is generated by providing these managed services and by offering high-speed fibre broadband to residential and business customers.

A core offering is the company's CityOS platform, an operating system that integrates data from various IoT sensors and city systems into a single dashboard. This allows municipalities to manage public assets in real-time, leading to operational efficiencies. For example, in Sheffield, the platform is used to monitor highway maintenance, alerting operatives when grit bins need refilling or drains require clearing, thereby reducing unnecessary journeys and associated carbon emissions. In March 2025, CityFibre acquired Connexin's full-fibre network infrastructure, a strategic move that allows Connexin to focus on its IoT and smart services business while expanding its reach across CityFibre's national network.
