InsideView a Decent Research Tool

We've found InsideView to be a good balance between industry-specific research sites (that have great info, but fewer companies profiled) and catch-all data aggregators (that have lots of unreliable or incomplete info). We really like the Family Tree function, which helps us determine ownership structures in large organizations. Since we do a lot of account-based marketing, this is crucial to tie leads to one another. Overall we find them to be great for organization research, and a secondary source for lead research (after LinkedIn and EtailInsights).
