Doesn’t “consolidation” mean “less vendors exist because they are being consolidated”?
Transferring the ownership of Marketo from Vista to Adobe does not consolidate anything.
The same number of marketing automation vendors exist today as did yesterday, so no consolidation has taken place.
Same for when Oracle bought Eloqua. Same when ExactTarget bought Pardot and was subsequently bought by Salesforce. No consolidation there either.
In fact, in martech, the trend is the opposite of consolidation. It’s proliferation.
