About Leadspace: Leadspace is a social demand generation solution. Leadspace learns who your ideal buyer is by analyzing some of your existing customers. It then discovers look-alikes by comparing people’s online presence – their social network profiles, conferences they go to, their social graph, and more – to your unique ideal buyer profile. It is no ordinary database. It gathers data, when you need it, from numerous sources – including social networks, contact databases, web sites and your CRM.
