My company is venturing into the world of quantified self and user generated data with our mobile app. Investors are pushing us to financially model future revenues on these services. We certainly have a good handle what users would pay to access premium services. However, we’re not finding a good information source of what 3rd parties pay for comparable user data. For instance, what are general price points for the de-identified data of a freemium fitness / wellness app user? And what multiplier, if any is placed on that data if the user is actually a paying premium customer?
