These days, software as a service, or SaaS, is the most common way of selling software to both businesses and consumers. It’s easier than shipping physical packages, more cost-effective, and provides a variety of other benefits. Salesforce—one of the most highly valued cloud computing companies in the world, with a market cap of $56.5 billion at today’s writing—staked the future of their entire business on the SaaS model. Back in 1999, the company accurately predicted that their customers didn’t want or need on-premises software. Other software companies followed suit and made the transition to the SaaS model. The subscription model worked, gained traction, and took off.
