Our take

Over the course of well over a decade, Sinch has grown into an international service helping enterprise companies communicate with their customers over text, in-app video/voice messages, and other mobile channels. Used by Google, Tinder, Uber, and PayPal, among other marquee enterprise companies, most customers will have crossed paths with Sinch.

The company’s rise is due in part to an increased marketing focus on cultivating a highly personalised relationship between customer and brand. In part, too, it’s down to the surge in custom Sinch saw over recent years when more familiar channels of customer/brand communication went down. That seems to have settled now, but personalized messages, over text specifically, continues to play well among younger consumers.

It's going to prove a tough market to navigate going forward, though. Equally well-established competitors like Twilio, 8x8, and Link Mobility Group all have similar offerings. Sinch's foray into conversational AI will help them keep pace, as will their steady march of acquisitions, fundraising to fuel scaling efforts and partnerships with the likes of Salesforce.
