Whichever governance software you choose, remember that owning a hammer doesn't make you a carpentry business, just as having a data governance tool doesn't make your initiative happen. Governance is really about your processes -- the actual gathering and cataloging of data and how you think about data.
Meanwhile, whatever you do, don't listen to the naysayers and throw your data away because you haven't figured out how to govern it yet. That's like killing the patient because treatment is a lot of work.
