Nexmo's mission is to take SMS global, putting messages on the 5 billion smartphones across continents and languages, with 800 carriers in 200 countries. As Alex Williams noted in Techcrunch, Nexmo raised $3 million from Intel Capital, NHN Investment Corporation and Initial Capital. Nexmo is:
"one of a new generation of companies that are disrupting the telco market. It streamlines the layers between the telcos and developers, removing the hubs by offering a carrier grade service based upon a worldwide network that gives companies like Airbnb an international messaging platform for communicating between buyers and sellers over SMS."
