God bless the IT disrupters, those startups and established vendors that have caused enterprises to rethink and even redefine the way they evaluate, buy, deploy, manage and use information technology.

The following enterprise IT disrupters list is a natural successor to the top 20 list of the most strategic enterprise IT vendors that I laid out in February of this year. As before, these selections, which take into account input from several InformationWeek editors, are presented for your evaluation and critique.
