Crowdsourced network-map service OpenSignal has announced that they have raised $4 million in a Series A round led by Qualcomm Ventures, the investment arm of telco giant Qualcomm. Also participating in the round are San Francisco-based O’Reilly AlphaTech Ventures and London-based Passion Capital.
The service, which maintains offices in London and San Francisco, previously obtained $1.3 million in a seed round from this same group of investors back in September, 2012. CEO Brendan Gill writes that they plan to use the new funding primarily to expand their team.
OpenSignal offers free, and ad-free, iOS and Android apps that allow mobile users to search local cell and WiFi networks to determine their strength. Both apps have been installed more than 5 million times.
It is a crowdsourced service, taking data from users to provide a map of local towers and to rank local networks. Thus far, they say that they have mapped more than 824K cell towers and provided more than 5.1 million signal readings.
Last year, the company launched WeatherSignal, a crowdsourced weather map. Since launch, the weather-oriented app has been installed hundreds of thousands of times.
