Oxford Properties Group completes 159,860 s/f office lease to Klaviyo at 125 Summer St. office tower

Boston, MA Oxford Properties Group (Oxford), the global real estate arm of OMERS, completed a 159,860 s/f lease to Klaviyo at 125 Summer St. Klaviyo, a marketing automation and email platform, will become one of the biggest customers in the building and join other building customers including Asics, Analog Devices, Haemonetics, and Tatte Bakery & Café. The 495,000 s/f boutique office tower occupies a full block adjacent to Dewey Sq. 

Following a surge of growth and investment over the past year, Klaviyo looked to expand its headquarters location by 135,000 s/f. With the addition of the new space, the company will occupy seven consecutive floors, taking the entire 5^th through 11^th floors.

“125 Summer St. is the ideal location for growing companies like Klaviyo,” said Matt Polhemus, director of leasing at Oxford Properties Group. “Klaviyo selected 125 Summer St. as a one-of-a-kind location to solidify their success and rapid growth, and we are happy they chose to grow their footprint with us.”

In the fall of 2016, Oxford originally signed a lease with Klaviyo for 25,000 s/f at 225 Franklin St. There were plans to grow to 75,000 s/f within 225 Franklin; however, as Klaviyo’s space requirement continued to increase, Oxford and Klaviyo pivoted to a 160,000 s/f block of space at 125 Summer St.

“We could not be more excited to expand our global headquarters right here in the heart of Boston at 125 Summer St. This is our city, it’s our home and Klaviyo is committed to building the next pillar technology company right here in the center of everything. With this location, we can vastly expand our workforce and make a positive impact on the greater Boston community for years to come,” said Steve Wietrecki CRO at Klaviyo.
