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.

Researcher Mid-Market (51-1000 emp.) 5/23/2022 "Great for finding relevant KOLs in niche concepts" 5/5 What do you like best about Key Opinion Leaders (KOLs)? As a researcher, I really like to be able to find opinion leaders and influencers with a good reputation in niche topics and scientific concepts.

We use it to understand what researchers are the most knowledgeable" 5/5 What do you like best about Key Opinion Leaders (KOLs)? For context: I am a researcher working at one of the leading cancer research centers in the US. My area of research is relatively new (gene therapy, CAR-T, etc.), and it is often difficult to know which researcher knows about what, especially if the colleagues in question live in a different country. The only way to have that kind of visibility on "who is who" would be to read all the research papers that come out, which would be more than a full-time job. With this platform (key opinion leader), I can do a couple of things: 1) I can look up colleagues by name and see what level of recognition (numerically) they have for specific concepts (KOL score, they call it), and 2) I can look up concepts (therapies, techniques, devices, medical conditions) and see who are the top leading experts (they call them KOLs or KOL in the platform) for that specific concept. I can then filter by organization and find the thought leaders/doctors/researchers that would be easy for me to reach. I can apply filters to filter down the list of key opinion leader until I get to the exact list of KOLs I need. I haven't seen any other tool that lets me do that. I love that it is free, so I didn't have to ask the department to purchase anything, which I imagine would have been a long process. Everyone in our research department uses this tool instead of the traditional research publications repositories as it aggregates data and scores at the "people level" (KOL scores) instead of just citations for papers authored (as pubmed, etc.). Review collected by and hosted on G2.com. What do you dislike about Key Opinion Leaders (KOLs)? nothing I can think of really, the tool is accurate and free Review collected by and hosted on G2.com. What problems is Key Opinion Leaders (KOLs) solving and how is that benefiting you? finding who knows about what and being able to compare other key opinion leaders on an equal basis (numeric score) for a concept. We use this tool to understand who knows about what without having to read all the papers that come out. It is a big time saver and our productivity has increased.
