Why not let us take a sample of the data currently sitting idly on your drives? We can perform some preliminary testing, and then determine a feasibility strategy for next steps. There is no risk involved. We will sufficiently anonymize data so that, if so desired, results can be shared firm-wide.

Most important insights and value emerge out of these relatively simple and straightforward analyses. Deeper steps may or may not provide more insight. Let's begin with the "low hanging fruit" via a quick data sample and move along, as necessary, from there!
