Gary Vaynerchuck, author of The Thank You Economy, partnered with ADstruc to create an outdoor billboard ad campaign that utilized Twilio's API for real-time communication with his fans. The campaign was a success, receiving over 250 personal phone calls in just a few weeks as users called a phone number on the ad and were forwarded directly to Gary's cell phone. Integrating Twilio into the campaign made it easy to enable instant communication between advertisers and their customers, providing new metrics for outdoor advertisers to measure ROI.
