Sugar CRM is an open-source customer relationship management software program that has been primarily designed with start-ups in mind. By having a clear focus and a target demographic that is in desperate need of an effective customer relationship management software program, Sugar CRM has managed to carve out a niche for itself in the industry as the go-to application developer for cash-strapped businesses that are in need of an immediate digital solution for their complex financial obstacles. Part of the reason for Sugar CRM's success lies in the open-source nature of the program. By being open-source, Sugar CRM allows its clients to make their own changes directly to the base code of the program. While this is great for companies that want greater versatility and flexibility from their customer relationship management program, it's also perfect for companies that are constantly evolving due to rapid growth and expansion.
