Eagle said the United Nations spends approximately $5 million per year to do surveys on disaster preparedness with face-to-face interviews. Txteagle helped the U.N. with its disaster preparedness surveys this year, and got more than five times as many people to participate via mobile phones in 49 countries for a fraction of that cost. Meanwhile, customers in Txteagle’s emerging markets average 10 percent of their annual income spent on their phones, so they value participating as well.
