Over 1 billion people lack access to reliable power, and yet 700 million have access to a mobile phone. For many, getting their phone charged and connecting to the network is a daily challenge. Without the ability to connect, these phone users will struggle to function in the modern economy.
We want to see everyone connected. We think everyone has the right to be included in our digital world. That’s why at BuffaloGrid, we are working to help the Next Billion get connected and stay connected.
Our team is made up of designers, developers and growth specialists who want to use technology to make a real impact in our user’s lives. They work across hardware, software, operations and growth to provide a reliable service that our customers want and our users love.
We are supported by Local Globe and Kima Ventures, two of Europe’s best venture capital funds. We are also the recipients of grant funding from InnovateUK, EU H2020 and the Microsoft Energy Access Initiative. And we are honoured to have been nominated for the UK Design Museum’s Design of the Year Award 2017, one of the most prestigious awards in design.
