SAN FRANCISCO—Platphorm‘s new lease at 799 Market Street brings the 142,903-square-foot project to 100% occupancy, says the property manager Jamestown, which owns the building.

Situated on the northeastern corner of Market and Fourth streets in downtown San Francisco, the property includes five floors of creative office space, featuring tall ceilings, large windows, abundant natural light, and open floor plans, atop 55,000 square feet of retail.

Platphorm signed for 5,591 square feet on the fourth floor and is expected to occupy the space in the spring of this year. This is a new office for the growing technology company, a multi-modal marketplace for information exchange and paid advice. CBRE represented Jamestown in the transaction, while Jones Lang LaSalle handled the negotiations on behalf of Platphorm. Ross for Less occupies the entire retail portion of the property.

“Platphorm’s lease and similar moves by other tech tenants signify that this sector is moving closer to the CBD. 799 Market provides them with that proximity while retaining the SoMa culture,” said Michael Phillips of Jamestown. 

Jamestown acquired the mixed-use asset in October of 2012 and has implemented a multi-faceted renovation program to reflect the creative sensibility and needs of the community. The lobby features unique bicycle-themed art installations, furniture and graphics to showcase the building as bike friendly. 

799 Market also recently signed top technology companies Prism Skylabs and Akamai Technologies, Inc.

Jamestown owns a neighboring mixed-use property comprised of two buildings at 22 Fourth and 801 Market. Demandforce, a division of Intuit’s Small Business segment, recently leased the entire office portion of 22 Fourth. 

Jamestown’s properties across the country draw a venerable roster of technology, creative, and media tenants including Google, IMAX,, NBC Entertainment, Lionsgate, and Makerbot.
