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. But the battle for mobile business communications may prove a long one.
