Ellie Mae might sound like Fannie Mae's cousin, but they're just in related industries, not bloodlines. The company provides automation software and operates the Ellie Mae Network that facilitates the residential mortgage origination and funding process. Its Encompass software suite combines loan origination with CRM (customer relationship management) to gather, review, and verify data from a single database. Other programs handle regulatory compliance, appraisal and title services, underwriting, tax transcripts, and document preparation and management. More than 136,000 mortgage professionals use its software and network to process more than 3 million new mortgages, an estimated 20% of its addressable market.
