Sending SMSes is their core offering, for sure, but I think that's selling them short. They also offer programmable text+voice, chat rooms, video chat etc. Lots of useful stuff for building/bootstrapping your own platforms. Their other product (through acquisition) is SendGrid, for transactional emails. I imagine what's next is more of the same: solutions to do with different ways of communicating. Perhaps no-code/low-code variants to many of their offerings, much like what Stripe is doing (powerful technical layer, but also very business friendly introductory solutions)
