Constant.Co has built a platform thats reshaping the way marketers around the globe promote consumer products online. It allows marketers to build rich shopper experiences that are platform and retailer agnostic. We call these experiences Landing Spaces. They can build these experiences once and then syndicate them to any social network or ad network, targeting audiences that are segmented by retailer. Landing Spaces experiences support every stage of the path to purchase (awareness, engagement, consideration and conversion) and let shoppers check out seamlessly at their preferred retailer. This radically alters the economics of digital marketing. Instead of wasting their budgets on fragmented, generic activity, marketers can devote their ad spend to building high-impact, high-ROI experiences tailored to specific audiences, and then reach those audiences on any platform.
