What do you get when you marry a team of geospatial user experience experts with a sale and marketing group? A vision to revolutionize location-based advertising. Having identified a strong market demand for an effective model to geo-target online advertising, lat49 was born in Vancouver, BC in early 2007 and officially launched its mapvertising network at TechCrunch 40 in September 2007. Everyday, there are new examples available on the Web of how people are combining data with maps to create insightful new methods for viewing and analyzing information. These map-centric Web sites attract an interactive audience of repeat visitors. This is an active and engaged audience that has been virtually inaccessible to advertisers... until now.
