UNICEF clients Erica Kochi and Christopher Fabian were listed among Time Magazine’s 100 Most Influential People of 2013 for creating text-message based applications in the developing world. They spearheaded RapidSMS, the open source web framework used for applications like sending infant HIV results via text in Zambia. Caktus worked directly with Kochi and Fabian and were instrumental in the core development of RapidSMS, the creation of RapidSMS.org on behalf of UNICEF, and initial RapidSMS applications in Africa.
