About Sinch

Who we are

Sinch is a cloud-based, mobile communications platform that makes adding Voice, Verification, Video, SMS, and IM into apps easier than ever. Originally spun out of Rebtel in May 2014, the team has over 100 years of development experience in the voice industry, and brings this skill and expertise to its powerful range of SDKs and APIs for developers’s use.

Our goal is to make it easy for developers to add voice, verification, video, SMS, and instant messaging to apps, enriching the modern app experience and becoming the preferred partner for modern app communications. For developers, Sinch removes the complexity of building and maintaining complex communications infrastructures, and handles the heavy lifting with a simple to integrate SDK that any developer can use.

In less than a year, Sinch has built a successful real-time communications platform and signing major clients like Tango, Truecaller, Easy Taxi, Glide, Nimbuzz, and more.
