Is there diversity and variance among my customers such that they will benefit from aggregating others’ data with theirs? For example, a company selling farm inputs (seeds, fertilizer and pesticides) can collect data from farmers with dispersed plots of land to determine which combinations of inputs are optimal under different conditions. Aggregating data from many farms operating under diverse soil, climatic, and environmental conditions can yield much better information about the optimal inputs for each individual farm than any single farmer could obtain from his own farm alone, regardless of how long he had been farming that parcel.
