Zuora powers Zoom and other subscription based businesses. Here is a fantastic video from their CEO, Tien Tzuo, on how product companies that are shifting to subscription based models are growing faster than the overall market.  Several products including washing machines and refrigerators are getting smarter, thanks to software.  You now have data to know exactly how clients are using products - which essentially makes you a SaaS company.  Leveraging that data to serve clients better leads to stickier revenues, higher lifetime values (LTV) and faster growth.  

Financing simply spreads out the purchase price over 24-36 months. Subscription businesses use data to serve customers better in addition to lower upfront costs.  This customer centric thinking, "customers can leave me anytime but will not if I serve their needs consistently," is what will lead to higher growth for product companies over the next few years.
