Today, Twilio powers the delivery of billions of the world’s communications. Increasingly, we’re hearing from our B2C customers that they’re struggling to harness the massive amounts of valuable data they generate, much of which stems from the communications we help them send. We seek to uncover how Twilio can help customers utilize their valuable data to create unique, individualized experiences that their competitors can’t replicate. We want to help them become more proactive (outcome-driven) than reactive (event-driven) in their customer engagements. We are a new initiative and team at Twilio that will function much like an internal start-up. If you want to shape the future of B2C Customer Engagement and Twilio, this project is for you!
