Software-as-a-Service (SaaS) tools are being used everywhere—from real estate to e-commerce. They help businesses manage their work more efficiently and effectively. From managing customer relationships to handling logistics, SaaS tools power much of the digital work. While these applications may appear simple to the user, a great deal of thought goes into how they are built and improved over time. Behind each successful product is a mix of data, user research, and constant iteration. As competition in the SaaS space increases, developing the right product effectively has become crucial at this time.
