Ask HN: Find users analyzing data across multiple spreadsheets

I am trying to identify users that analyze data spread across multiple spreadsheets: - typical roles and titles of such users - type of organization where such users are likely to be concentrated - industry verticals that are more likely to have such users - how to reach such users? We are developing a service that helps users performing data analytics work who, - need to answer questions by querying data but not necessarily familiar with handling of raw data - expecting quick turnaround and driven by urgency of finding interesting and relevant patterns in data collected from disparate sources. We are having second thoughts now as we are realizing finding our target users appears to be difficult. Any suggestions and feedback most appreciated.
