D.light: Story, Founders, Investors & Funding Rounds

Founded in 2006 at Stanford, d.light is a global leader in solar energy, dedicated to providing the most reliable, affordable, and accessible solar lighting and power systems for people living in developing countries.

D. light currently provides distributed solar energy to households and small businesses in 70 countries and has impacted over 100 million lives. Innovative funding models have made d.light easily affordable, while sustainable designs have established confidence in the sustainability of solar energy

In 2004, Peace Corps volunteer Sam Goldman’s neighbor was badly burned in a kerosene accident in Benin, Africa. Sam knew there had to be better, safer ways to power homes and businesses in the developing world. After returning to North America from the Peace Corps, Sam enrolled in Stanford’s Entrepreneurial Design for Extreme Affordability class, where he met co-founder Ned Tozun.

In 2006, Ned and Sam founded d.light, developing the initial prototype solar lantern and an ambitious plan to bring safe, bright, clean lighting and power to people around the globe. d.light’s first commercial solar product made its debut in the marketplace in 2008.

D. light is a global leader in social transformation by making transformative products available and affordable to low-income families. Most of the customers they serve don’t have access to reliable power or financing, and d.light removes those barriers. 

They enable reliable power through their solar energy solutions and enable financing with their Pay As You Go technology. 

D. light has sold over 25 million products including solar lanterns, solar home systems, TVs, radios, and smartphones, impacting the lives of over 125 million people.
