Starry, a US-based internet service provider backed by media and internet group IAC, has closed a $100m funding round, the Boston Globe reported on Thursday.
The investors have not been identified. Starry raised the first $31m in December 2017 when a regulatory filing indicated the company was seeking a $55m final close.
Founded in 2014, Starry has developed high-frequency radio technology that can deliver high-speed broadband at up to 200 megabits per second.
The company uses the system to provide high-speed internet to customers from a price of $50 per month. The service is aimed at apartment buildings and relies on a small exterior antenna that is wired into the existing communications infrastructure.
Starry manufactures its own hardware, providing users with a wifi hub that can be used to set parental controls, check internet speeds and contact customer support.
The money will help Starry expand further across the US where it is currently available in 16 cities including Los Angeles, Washington DC and Chicago.
Starry has raised $163m to date, including $30m in series B capital from IAC, HLVP, FirstMark Capital, Tiger Global Management, KKR and Quantum Strategic Partners, a vehicle managed by Soros Fund Management, in 2016.
