Twilio wants to be an end-to-end 'customer engagement platform' so this is a super strong acquisition; in one go they've bought a huge chunk of the marketing automation eco-system, which pushes them really far up the customer value chain.<p>From a personal perspective it'll be interesting to see how much this pulls/pushes Twilio into the ad-tech space.<p>Segment's 'Customer Data Platform' really found its legs in the marketing space, but they've recently made a very big push to a 'we can do everything your DMP does and 100x more' which was making pretty big waves in the sell side of ad-tech. One of the reasons I think it's so successful is their developer experience is about a million times better than their competitors.<p>If Twilio does continue this push up through marketing into ad-tech I'd be very long on them eating a nice chunk of that market.
