Ubuntu 2S is a Bissau-Guinean start-up specializing in solar energy technologies and ICTs. Its main mission is to help solve the problem of lack of electricity in sub-Saharan Africa. The startup offers intelligent SHS kits, developed with open solutions (Angaza), with a business model based on recurring payments via Mobile Money. Several SHS kits in CASA range are available, including LED bulbs, charger cable for phone, radio, TV and fans. Specific kits+Solar kiosks (Business range) for social entrepreneurs are also under study. With our payment model "PAYSGO" which allows our customers to pay a small amount per month for a few months to become an owner of a solar kit with a lifespan of more than 7 years and our payment model "PAYFORME" which puts in contribution the African diaspora and other people of good will who want to know that they giving access to electricity to a family somewhere in Africa by paying only less than 10 euro per month without feeling it on their salary, We believe we can effectively contribute to accelerate the SDG7 by giving access to electricity to the 600 million Africans who do not have it by 2030. Ubuntu 2S was awarded in 2018 with the 2nd place of the Seedstars Bissau competition.
