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)

Asana is the shocker for me. I've seen many, many enterprises big and small and barely a handful were running Asana. And none of them liked it.

I love it. We’ve used it for years.

Asana has been an incredible upgrade from JIRA. We switched two weeks ago and it's the best project management solution I've used by miles, nothing even begins to compare.

Their peak stock price was like 20% higher than right now. With a lot of similar cloud companies hitting all time highs, Twilio’s market cap would exceed $75B if they hit all time high again. Acquisitions can do quite a bit. That’s how Salesforce runs :). Twilio bought Segment for $3.2 in stock.

They seem to be expanding successfully into video and email. I'd expect the next big lift to be the sequencing of those different mediums.
