San Francisco based startup, Angaza is changing the way off-grid communities in emerging markets access energy with their Pay-As-You-G0 software for Androids. Angaza has now raised a Series B round of $10.5M to scale its innovative solution. Laurene Powell Jobs’ Emerson Collective led the ground and was joined by Rethink Impact, Salesforce Ventures, Social Capital, and the Stanford StartX Fund. It previously raised a Series A funding of $4 million. The new round means an Angaza has raised $16m to date. In the last two years, Angaza has reached 2 million new solar users in 30 countries. How did they scale so fast?
