I am a product lead at a software company unrelated to healthcare but we use Key Opinion Leaders to identify areas (cities, states) with high activity in certain areas or business verticals and then use that intel to do market research on upcoming events related to those verticals in specific cities. We use this as input to design our marketing efforts and budget allocations. So far our effectiveness seems to have improved by a lot and are getting a lot of leads that are converting at a higher rate. Review collected by and hosted on G2.com.
I wish I could filter by arbitrary concepts instead of the predefined options in the UI Review collected by and hosted on G2.com.
