Software as a Service has been around since the 1960s. SaaS model saw a sudden boom in the 1990s with the shrinking cost of computers. Today, the SaaS marketplace is much larger than it has ever been and is, interestingly, continuing to grow. With applications ranging from uses in CRM, business intelligence, e-commerce, financing, and HR (to name a few), the SaaS domain is highly competitive. Maintaining a steady stream of high-quality leads is very critical in such an environment.
