DoubleDutch Raises $19M to Grow 'Relationship Mapping' Mobile Event App

DoubleDutch Inc. raised $19 million in Series D venture funding to popularize its data-driven social-event app, in the U.S. and in Europe, the Middle East and Asia.

The DoubleDutch app gives attendees of trade shows and other major conferences a way to find and connect with businesses and people who share their interests before they arrive and on-premise during the event, and a way to stay connected even after they leave.
