We talk about usage of our product almost constantly at Passle. We know that by getting the Experts inside our clients to engage with their customers we can unlock phenomenal value. So by comparison to other products and services, we can invest very heavily in customer success and support. 

But we are clearly not alone, Salesforce is suggesting that the sales team themselves, not a second department, will soon be compensated by usage, not deals. For Passle, because of the way we sell, this is already true. We do an initial deal, our clients like it and so buy a little more, and a little more, and tell their friends... who tell their friends...
