4) “Pure play” lead management – this group is lead by Eloqua , but there are a LOT of firms throwing their hat into this ring including Vtrenz, Hubspot, Manticore, Market2Lead, Marketo, LoopFuse, einsof, iHance, Precience, among many others. Positioning yourselves as “lead management” does not help differentiate what you REALLY do. In B2B, it’s not about batch-and-blast acquisition as much as it is about using email to continue a conversation. How do you differentiate between these two in conversation? Too many with too little differentiation. Exciting times.
