Public company Mimecast recently moved its North American headquarters from Watertown to Lexington, Mass.

Since 2008, Mimecast’s North American operations have been based in the greater Boston area: first in Waltham, then in Watertown and, most recently, in the new Lexington location. The move will help accommodate the company’s growth, doubling its footprint to 79,000 square feet and enabling the company to hire new people in sales, engineering, customer service and marketing.

The extra space also enables the company to expand the perks offered to the current 360 Massachusetts-based employees, including an open work environment, free lunch four days a week, covered parking, a gym and a 1,600-foot roof deck. Additionally, the building has a sustainable design with features including a rooftop solar photovoltaic (PV) system, the company said in a press release.

“Mimecast has been in the Boston-area for nearly 10 years, and the company has seen tremendous growth since we first made our footprint with five employees in a small office in Waltham,” said Peter Bauer, CEO and chairman of Mimecast, in a statement. “Mimecast’s success is the result of vision, passion and dedication of our employees known as ‘Mimecasters’ and the focus on customer success around the globe.”

Mimecast is perhaps best known for providing cloud-based email archiving, continuity and security for a suite of Microsoft’s products, including Microsoft Exchange and Office 365. It trades on the Nasdaq Stock exchange.
