South Boston Waterfront to get another corporate headquarters - and a celebration of its maritime past

Skanska said today that PTC is leasing 250,000 square feet of space in its new 17-story office tower at 121 Seaport Blvd. and will move its corporate headquarters there from Needham.

PTC, founded in 1985, makes software for "augmented reality" and to connect traditionally "dumb" devices into "Internet of Things" networks. It will move 1,000 employees into the top half of the tower, which, unlike most other buildings around here, has an elliptical shape. PTC has 6,000 employees worldwide.

In a statement, PTC said it expects the new location to help it hire and retain skilled workers who want to be in the heart of a growing technology district.

The company adds it plans to use its "augmented reality" chops to commemorate the district's maritime past:

A “walking museum” is planned for a pedestrian promenade adjacent to the building, celebrating the Boston Seaport's maritime history.
