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.
