These are complete guesses, but I would expect you could charge businesses more in the order of $50&#x2F;month per user, if not higher... and just one business might sign up 10 people, which would be $500&#x2F;month.<p>That means that a single business signup could be worth 100x a single individual signup.<p>Individuals are price sensitive to the point where $5&#x2F;month is still something they have to think hard about. Businesses can spend a great deal more than that.
