How big a problem is zombie martech? Half (51%) of the respondents to this Demand Metric survey for Integrate said they have a great or very great amount of redundant or unused tech. But they don’t seem too worried about it: 64% said their current martech stack supports them well or very well, 44% plan to increase their marketing ops and martech spending, and more plan to add new systems (32%) than to make their stack smaller (26%). Interesting.

Just over one-third of marketers plan to either buy a new CDP (21%) or replace an existing one (13%) this year, according to this Optimove survey. Unfortunately, it doesn’t report how many have a CDP already in place, which would put the other values in perspective. It does seem that CDPs are a relatively low priority: they rank sixth on the list of new systems and eighth on the list of systems to replace.
