Software firm Ellie Mae is taking the top floors of 4420 Rosewood Drive, California Center, in Pleasanton.

PLEASANTON, CA—Ellie Mae, has signed a long-term lease for more than 100,000 square feet of office space that will be the site of its new corporate headquarters in Pleasanton.

The company, a leading provider of innovative on-demand software solutions and services for the residential mortgage industry, currently occupies two smaller buildings in Pleasanton, and will nearly double its existing office space to accommodate the needs of its growing workforce, which also has about doubled in size in the last two years to more than 500.

Sig Anderman, CEO and founder of Ellie Mae, said, “Our employees work hard and deserve the very best working environment, which is why we are excited to bring our headquarters team together under one roof in a single location with so many great amenities.” He added, “The additional space will enable us to continue to grow our staff to meet the needs of our expanding customer base.”

The company expects to move into its new headquarters in Spring 2015.

Ellie Mae will occupy the newly renovated top three floors of 4420 Rosewood Drive in California Center, a corporate business park in the heart of the Bay Area’s fast-growing Tri-Valley area.

Ellie Mae employees will have access to a state-of-the-art fitness center, a large cafe with numerous food options, multiple conference rooms, several auditoriums with webcasting capabilities and several new amenities to be added by the project’s new owner Swift Real Estate Partners. Ellie Mae also plans to create a first-class executive briefing center within its new headquarters as a demonstration of its strong commitment to its customers in the residential mortgage industry.
