B to b is where people are able to show demand prior to having a product, and really early. We lookad the start up that was going to do artificial intelligence based on booking specifically for fitness companies. They went out and talked to several hundred fitness studios, and they got 91 letters of intent from finnes studios saying that, once you build this, i will pay x dollars a month. And so that's a really good example of a kind of demonstrating interest, even though they were pre revenue, pre product.
