Square puts down roots in Market tech corridor

Mike Koozmin/The S.F. ExaminerUpgrade: Square

Square, the mobile payment system company started by Twitter co-founder Jack Dorsey, is the latest tech startup to announce that it’s relocating to the mid-Market Street area.

On Monday, the company said its corporate headquarters will be moving to 1455 Market St., less than a block away from Twitter.

“We’re grateful for San Francisco’s commitment to technology, and we’re thrilled The City will remain our home,” Dorsey said in a statement.

The company is currently located in the San Francisco Chronicle building at Fifth and Mission streets, a site that made more sense when Square had 10 employees, the company said. With more than 400 employees now and plans to grow to 1,000, Square said it needs a larger site.

Plans for the new space, located near 11th and Market streets, include a roof deck, a collaborative space and a kitchen to prepare meals for workers, the company said. Renovation work is expected to begin at the end of the year, and the company said it expects to move into the new location in mid-2013.

The stretch of Market Street has been the focus of Mayor Ed Lee’s push to attract and retain tech companies.

“Square is one of The City’s great technology companies and will be a great addition to the central Market as revitalization continues in the community,” Lee said in a statement. “I would like to personally thank Jack Dorsey for his commitment to San Francisco.”

Twitter moved into its new headquarters in the art deco SF Mart building at 10th and Market streets in June.
