Do you know anyone without a mobile phone? Neither do we

That's why back in 2008, our founders set out to reinvent mobile messaging. They realized that SMS presented an incredible opportunity for companies due to its immediate and widespread reach - but it needed a change. They wanted to make mobile messaging easy - to make it a “sinch”, if you will. 
Since then, Sinch has grown from six people in a little Stockholm shop window to an international powerhouse serving enterprises across the globe. In fact, IDC MarketScape says we’re a CPaaS Leader! Our cloud platform now supports messaging, voice, and video, and handles 145 billion engagements per year.
