At CityFibre, we’re building a new, intelligent, open-access fibre network, purpose built for the data age. We’re upgrading communities across the country, giving people a better foundation for their digital lives, enabling businesses to innovate, and helping to strengthen the UK economy.
Our national networks are expanding rapidly, and we are already the network of choice for major Internet Service Providers and mobile operators including TalkTalk, Three, Vodafone and Zen, as well as dozens of exciting smaller providers.
Using our networks, our customers can provide theirs, be they homes, businesses, schools, or hospitals with broadband, Ethernet and mobile connections so quick and reliable, you can practically take them for granted.
With almost two million premises already passed, our fully financed rollout programme is on track to serve a third of the UK. That’s around 8m homes, 800k businesses, 400k local authority sites and 250k 5G access points that will soon have access to the UK’s finest digital infrastructure.
SPEEDLINK products are manufactured by the internationally active company Jöllenbeck GmbH. Founded in the year 1974, the company can look back on a long tradition in the fast-paced electronics industry. Jöllenbeck has contributed to the development of this sector with exceptional energy and creativity. The company has done true pioneering work. Over 200 employees at the headquarters in Germany alone are working to continue the company’s success story.
SPEEDLINK is one of the leading brands in computer and video game accessories in Europe. The products combine new technologies with excellent design and outstanding functionality.
SPEEDLINK has enjoyed continuous growth since its founding in 1998. Today, the company′s products can be found in over 30 countries in Europe. The over 10 million sound systems and over 15 million game controllers sold impressively demonstrate SPEEDLINK′s market presence.
SPEEDLINK product development is based on a willingness to innovate and an eye for the trends of tomorrow. The fast pace of the market demands great vigilance and a high degree of flexibility. Constant supervision of development work and production as well as the company′s representation on the market guarantees excellent product quality and forms the basis for continuing success.
Ecofibre Advanced Technologies is a U.S.-based performance materials enterprise specializing in engineered materials and fibers for demanding applications. We partner with brands and manufacturers to develop purpose-built material solutions that bridge polymer science, extrusion engineering, and scalable production.
Ecofibre’s integrated development model connects material design, process control, and real-world manufacturing requirements into a single, continuous workflow. This approach enables faster iteration, tighter performance control, and materials engineered to perform at scale—reducing risk as programs move from concept to commercialization.
From polymer to production, Ecofibre focuses on solving material challenges that conventional fibers can’t address. Our capabilities span polymer formulation, proprietary extrusion systems, fiber and yarn engineering, in-house testing, and market-ready production.
Ecofibre supports performance-driven applications across apparel, turf, biomedical, and other technical markets. We work collaboratively with partners to align material innovation with manufacturability, helping turn design intent into reliable, real-world execution.
We call this approach Fiber Evolution™ —an engineering-led model that links polymer development, extrusion control, and application insight to deliver fibers that meet specific performance requirements with greater precision. Partners work with Ecofibre for rapid R&D-to-prototype development, collaborative solution design, and agility from
small-batch experimentation to full manufacturing. Technical differentiators include additive-free processing options, controlled production environments, and in-house testing across tensile, elongation, recovery, wear, and environmental durability.
