Mayor Ed Lee continued to push the importance of tech companies in San Francisco on Tuesday morning at the TechCrunch Disrupt conference, where he said The City’s future is dependent on the industry.

Lee is always quick to mention his support for a payroll-tax break approved last spring for the mid-Market neighborhood and designed to keep microblogging company Twitter in town. Facing increased taxes at its current headquarters, the growing company said it was considering a move out of The City.

“I didn’t want to punish companies for growth,” Lee said, adding that he believed Twitter would have indeed moved out of The City without the tax help.

According to a story on the TechCrunch website, the mayor went further to say he’s considering steps to ax the payroll tax entirely. Lee also called for more comprehensive reform of the tax last week at the annual ForecastSF conference put on by the San Francisco Chamber of Commerce.

Lee has located his election campaign headquarters in the “enterprise zone” at Sixth and Market streets, where a new neighbor — Zendesk — moved in late last month. The software company became the first to take advantage of the tax exemption and joins a healthy string of investment in the area’s office buildings and housing.
