| Icaria's mission is to create a new society in which people will not lose their lives by using urine tests to provide "early, painless and accurate early diagnosis of cancer."It is known that detecting cancer early increases the survival rate 5 to 10 times and greatly improves the prognosis. However, it is not unusual for manycancers to have no subjective symptoms, and when they become aware they have progressed to a stage where treatment is impossible. The most effective way to detect cancer at an early stage that can be treated is to have regular and high-precision cancer diagnosis, but existing cancer diagnosis is painful and However, many of them are not accurate enough and are not suitable for regular diagnosis and early stage diagnosis. | $24.4M / Series D / Aug 18, 2026 | ||
| Eneza Education, a.k.a. MPrep, was founded in 2011 by Kenyan teachers and educators serious about making technology useful for their students. From the rural areas of Nyanza to Wajir Town and the Mombasa Coast, Kenyan teachers united to create the content of our initial Class 7 and Class 8 study tool. We wanted a tool that combined the best ofgreat teaching practices: scaffolded assessments, direct feedback, and high engagement. And we wanted to make sure ALL kids had access to our system. What better way to start than with a simple SMS-based system? | Seed / Dec 09, 2014 | ||
| SOKO is a manufacturing platform built using mobile technology to connect independent, distributed artisans to the global marketplace. Its technology suite and mobile app organize over 2300 independent, artisans throughout Kenya to manufacture their jewelry. It has created an efficient and demand-responsive virtual factory. Millenials and Gen Zconsumers are constantly looking for brands that align with their values and are opting for brands that adopt sustained and measurable social impact. Its business model and BCorp certification validate and distinguish us from our competition. Its model also provides economic opportunity and financial inclusion for marginalized artisans who are now earning 4.8X more than an average Kenyan workshop. So, unlike centralized factory production, they are using technology to empower human capital, not displace it. | Seed / Dec 09, 2014 | ||
| Eco-fuel Africa empower communities in Africa to use tailor-made technology, helping them convert locally sourced farm and municipal waste into clean cooking fuel and organic fertilizer. This helps to solve a myriad issues; it slows the rate of deforestation by reducing the dependency on fuel-wood, reduces indoor air pollution by substituting smoky wood with cleaner-burning fuel, improves educational opportunities among girls and women by eliminating the need to search for wood, and reduces malnutrition by providing farmers with access to organic fertilizer. | Seed / Dec 09, 2014 |
