Zola Electric delivers electricity to a million people in Africa daily through solar and battery systems designed for unreliable or absent grid infrastructure. Founded by Xavier Helgesen after witnessing a 20,000-person village in Malawi with zero electricity access, the company moved its entire team to Tanzania to live alongside customers and understand their true electricity needs. By working backwards from customer price points and substitute spending on kerosene and phone charging services, Zola built an accessible solar solution and has since raised over $100 million in equity funding to scale across Africa.

Jamie Siminoff built Ring, a WiFi-enabled smart doorbell with a camera, starting from a personal problem he couldn't hear his doorbell. The company grew to $480 million in revenue by 2017 with triple-digit growth rates, despite being cash-flow negative due to rapid scaling. After nearly losing the deal to Amazon due to an ADT lawsuit injunction, Siminoff settled the suit, and Amazon acquired Ring for $1.15 billion in December 2017, just weeks after the legal cloud lifted.
