Klaviyo Expands Boston Headquarters to More Than 250,000 SF
Marketing technology firm Klaviyo is significantly expanding its presence in Boston, signing a lease for 256,000 square feet at 125 Summer Street. The company, which already occupied 160,000 square feet in the 22-story Financial District tower, is increasing its office footprint despite a broader trend of downsizing among tech firms.
The building, owned by Oxford Properties, has increasingly become a hub for tech-related tenants. In addition to Klaviyo, other occupants include Analog Devices and medical technology provider Haemonetics. The property is now nearly 90 percent leased.
“Klaviyo committing to more space for a longer term at 125 Summer Street clearly reflects the high quality of our asset and our conviction in the continued demand for centrally located, sustainable buildings focused on curated employee experiences,” said Matthew Polhemus, Vice President of Leasing at Oxford Properties.
This move underscores Klaviyo’s growth trajectory and reflects confidence in its future expansion within Boston’s competitive commercial real estate market.
