Hear from a proven innovator in the STEM space, Mark Rober

Mark Rober has amassed over 8 billion views by creating incredible science-focused builds and pranks on his successful YouTube channel, with 65 million subscribers and counting. In the summer of 2022, Rober announced his secret project, called CrunchLabs, a massive Willy Wonka-style factory of creativity in the San Francisco Bay Area, where the team creates each original, buildable engineering toys and the super fun (and science-packed) videos from scratch with an express focus on getting as many brains as possible excited about science and engineering. If you’ve ever wondered how to apply a 'NASA-level' rigour to your own dev projects, this is the event you cannot afford to miss.

See what Netflix, Rivian, and Nestlé all have in common

SIGNAL features deep dives into how global giants are redefining customer engagement at an enterprise scale. Netflix will unveil its "playbook" for scaling global communications, detailing how it manages SMS and WhatsApp for over 300 million subscribers while tackling the massive technical challenge of sending 80 million messages in under 10 minutes for live events. Rivian will showcase its transition to a unified customer experience, demonstrating how it uses Twilio Flex to connect data across every interaction to ensure the digital experience is as seamless as the drive itself. Meanwhile, Nestlé will share the architecture behind its massive marketing expansion, explaining how it integrated Twilio with Salesforce Marketing Cloud to deliver personalized WhatsApp messaging across 12 different global markets. These sessions offer a rare, behind-the-scenes look at how the world’s most iconic brands are solving complex communication challenges at a scale that was once thought impossible.

At Twilio, we believe the same tools that power global enterprises should be used to solve the world’s most pressing challenges. For nonprofit leaders and social impact developers, SIGNAL is where to learn how to build high-impact, low-cost solutions that meet people where they are.

On Day 2, we are featuring a conversation between Bret Taylor, Cofounder of Sierra, and Khozema Shipchandler, Chief Executive Officer at Twilio.

Most recently, Bret was the co-CEO of Salesforce, where he served in a variety of executive roles after the company acquired his previous start-up, Quip, in 2016. Bret started his career at Google where he co-created Google Maps, and later joined Facebook, serving as its Chief Technology Officer after it acquired his social networking start-up, FriendFeed. At SIGNAL, he will bring an unparalleled perspective on how enterprise software is shifting from static "systems of record" to dynamic "systems of agency”. For any builder looking to understand the next decade of software architecture, this is the definitive session of the year.
