David Cancel discusses how sales and marketing teams need to adapt to the rise of messaging by implementing real-time engagement with website visitors. He argues that the traditional approach of using forms and follow-up emails is no longer effective, as research shows responses within 5 minutes dramatically increase conversion rates. Cancel presents Drift's solution called "Fastlane", which uses chatbots and live messaging to instantly capture, qualify, and connect leads, without forms. For companies not ready to fully adopt this new model, he suggests adding messaging as a secondary channel to complement existing tactics. Real-time engagement through intelligent messaging platforms is presented as the next wave in sales and marketing that companies must ride to succeed.
