Thank you for mentioning engageSPARK! Here's a quick summary of what we're building: Our first product empowers organizations to dramatically extend the reach and impact of their pro-poor programs. A not-for-profit business, we're building the easiest to use self-service cloud-based solution to easily and quickly launch comprehensive messaging, surveying, curriculums, and decision tree programs focused on developing countries via SMS, USSD and Voice Calls (roughly half of world’s poor are illiterate) in 200+ countries. engageSPARK will also be the first platform custom built for software developers in developing countries – they will utilize APIs to easily and quickly integrate into multiple telecoms across multiple countries for basic building blocks such as SMS, Voice, USSD, and Mobile Money.
