Like any great relationship, we started small with a few key shared customers, leveraging the Sinch/Blueshift integration and looking for ways to collaborate. Over time, with continued success and mutual growth, we've expanded into other Sinch product offerings and seen an increase in happy shared customers. The Sinch/Blueshift partnership truly is one of the most important to our business, and we're excited for it to continue to grow!”
