From Jonathan Schwartz’ interview:

Schwartz: I think it can definitely change our dialogue with our customers. If you look at our top 65 accounts, there’s 10 million people there. At $100 each that’s a billion dollars. So I think it certainly gives us a broader market opportunity

Mmmh… That’s about 150,000 employees per company in average.

Someone needs to brush up on their arithmetic.

but I’m not a good prognosticator about our revenue streams.

You don’t say.
