Every category
A category here is a tag, not a folder. A product carries every category that genuinely applies to it, so a front-to-back platform appears under several and a buyer filtering on two of them still finds it. Each category page defines the category in our own words, says who operates that kind of system, names what it is most often confused with, and gives the question that changes the answer when you put it to a vendor. The product counts below are of records in this catalogue, not of installations or market share.
42 categories covering the systems asset managers, hedge funds and private equity firms buy. Categories are tags rather than folders, so a platform spanning several appears under each of them.
