I listened to an amazing web programmer talk about the features of the Software-as-a-Service (SaaS) product he will have ready for launch in a couple of months. He's been working on it for years, and he is very passionate about what it can do. After seeing what the product can do, I believe there are potentially several commercially-viable applications for his product.
I am a fan of movement toward the use of the word "pivot" to describe the key business model changes a start-up implements in its quest for the most effective and scalable way to deliver its products/services to the market. I am an advocate of making sure that each of the pivots improves the cash flow and working capital cycle of the venture.
