This week, Travis and Stewart have been in Lisbon for Web Summit, where 53,056 people ate over 97,000 custard pastries, and the world's best minds came together to drop knowledge bombs across 17 stages. We reveal who we interviewed for our special VB Engage: Web Summit episodes, and discuss the highlights of the conference, before talking with the brilliant Veronica Belmont on how big brands are embracing chatbots, why discovery is a big issue, and what her favorite chatbot examples are, one of which is like having a therapist in your pocket.
