What ZenFi Networks does
ZenFi Networks was a New York-based, carrier-neutral dark fiber network operator founded in 2013, specializing in fronthaul, backhaul, and wavelength connectivity services for mobile network operators, enterprises, and venue owners in the New York metro market. The company built and operated fiber infrastructure designed to support densification of mobile networks, including small cell and macro backhaul transport. Its core product set comprised dark fiber leases, lit wavelength services, and metro connectivity solutions delivered over a carrier-neutral footprint, with the 2018 acquisition of Cross River Fiber extending its fiber reach and customer base.
ZenFi monetized its network primarily through wholesale, multi-year contracts with mobile operators (fronthaul/backhaul transport) and enterprise/venue customers requiring high-capacity lit or dark fiber connectivity, priced on a quote-based B2B model tied to route, capacity, and term. The company pursued an enterprise field sales motion targeting carriers, venue operators, and large commercial tenants. ZenFi has since been integrated into Boldyn Networks' US operations, joining a neutral host platform that spans North America, Europe, and Asia and adds DAS, small cells, managed Wi-Fi, private 5G, and Connectivity/Private 5G as a Service offerings on top of the underlying fiber base. The combined entity is described as one of the largest neutral host providers globally.
