Why?
The Growth Automation pillar is building a new platform to provide a one-stop shop for marketers to build delightful, personalized customer experiences across any channel based on a single view of the customer. Orchestrate a customer journey and send emails, SMS, push notifications, voice, video, whatsapp, onsite personalization - any channel that the customer prefers most with a relevant message they actually want to see. Our team’s goal is to help Twilio-Segment customers understand, aid, and delight their customers across every first party touchpoint and interaction.
Growth Automation is being built on top of the most sophisticated first party customer data platform in the world. Imagine a platform that can take the hundreds of thousands of messages entering Segment’s pipelines every second, add in a new identity graph, and overlay multiple high speed, realtime and batch databases — and you have the Personas platform.  We’ve since built several successful products on top of the Personas platform: Segment Audiences for real time audience management, Segment Traits for computation, and Profile API for real time personalization. We are now personalizing customer engagement by transforming raw customer data across all channels into actionable, individualized customer predictions that you can leverage in any workflow or process.
