I just browsed through the Tech M&A Banking Review from the 451 group. It was interesting, to say the least, as I realized - being an insider at Corum - how undisclosed data can highly skew, augment, corrupt the overall circumstances of a research document. We work through these same problems here and often use/site 451 data for our own projects... so I understand the increasing complications of undisclosed information.
What struck me as most interesting was that when looking at stats for Software M&A transactions, we were not ranked in the top-10 for volume. In fact, some of those who were ranked in the top-10, I know for a fact produce less deals than us.
I work in Tech and Real Estate. I love both of them.
