Improving Signal, Together

We're at the forefront of the new field of crowdsourced sensor networks and looking for smart, passionate and determined people to help us achieve our mission of becoming the global authority on wireless networks. This innovative technology and big data will allow you to work on a set of unique and complex technical challenges where the solution usually can't be looked up in a textbook.

What We're Building

At OpenSignal, big data meets sensor networks. Our mission is to become the global authority on wireless networks. Our main consumer products, OpenSignal (a top developer app) and WifiMapper (featured as best new app), are mobile signal, coverage map and WiFi crowdsourcing apps with over 13 million downloads around the world. OpenSignal enables consumers to stay connected better and longer and allows mobile operators to benchmark and improve their networks.

To date, we have provided wireless market insights to customers such as McKinsey, Opera, Telefonica and ChinaMobile. This data and our reports have also been covered by TIME Magazine, CNN and the BBC. Our research has also led to multiple papers published in scientific journals.

Our other apps:

WeatherSignal turns your phone into a portable weather station with the mission to enable more local and accurate weather forecasting. CrisisSignal provides real-time updates on the state of networks in the wake of disasters.
