Good idea, lumenge, although POETfablight might be right and it is a waste of time.
However, I would recommend not to ask closed questions like
Is the company worth more than $100 billion?
as the answer would simply be “No. Next question please.”
An open question might be (example only):
Could you please give us a rough idea what the valuation of the company should be by the end of this year and next year, and why?
