The Builder Keynote will go deeper into the Twilio platform, taking you behind the scenes of what you at the Visionary Keynote. You'll hear about how we're improving and expanding the Twilio fundamentals, and we'll get into the "how" of building on the Twilio platform. Be prepared for fun, some surprises, and maybe a few "undocumented features" - and no one will get lost in the cloud... we hope.
