This site provides access to thoroughly researched information in the Pharma industry -- both US data and global data. It's really the best site out there, and our clients are often clamoring for the data (decision points made by MDs, how they access information digitally, data broken out by country, specialty) ... we work with this company for access to information, as well as data visualization.

I like the breadth of data --- everything you could possibly need to know in the pharma industry, they have available. Plus, they update everything annually. Review collected by and hosted on G2.com.
