d.light

The off-grid solar company that grew out of a Stanford design class. Sam Goldman and Ned Tozun founded d.light in 2007 to replace kerosene lamps with cheap solar lanterns, sold first through shops and distributors in India and East Africa. It then moved up the product ladder to solar home systems with TVs, and from the mid-2010s into pay-as-you-go (PAYGo) credit over Kenya's M-PESA. Its distinctive move was financial. From 2020, d.light sold its Kenyan-shilling and other local-currency customer receivables into "Brighter Life" securitisation vehicles arranged by African Frontier Capital and backed by the US International Development Finance Corporation (DFC), Norfund and others: ~$65m in Jun 2020, expanded to a KES-equivalent ~$127m in Jan 2021, a DFC-listed ~$238m second Kenyan vehicle (2022), and a ~$176m Kenya–Tanzania–Uganda facility (Jul 2024). By Jul 2025 the company said its facilities totalled ~$842m (company). It claims to have reached ~190 million people (company, 2025). That is a modelled "lives impacted" figure, not a count of customers. Since 2024 it has also sold carbon credits from clean cookstoves and solar products, a revenue line that sits inside the integrity debate around household carbon credits.
