The tech community is a closely knit group, which is why it's so powerful. All of these companies have an affinity for each other, even if they compete with each other.

Tech people like to stick to their knitting, and they measure their accomplishments by the growth of their company. Now the tech community is popping up and saying, 'We do need to be involved in our surroundings.'

All the biggest companies are based on a founder who had a need, hacked it together, and said, 'Hey, other people might want this.'

I started sfCiti because I believed that technology companies needed to take a 'One City' approach and build a shared sense of community and civic responsibility in San Francisco.

Technology does more than delight, entertain and make our lives more convenient, it's also an agent for social good. That is why it's important for tech startups to stay informed about, and make a mark on, policies that impact them.

I am most proud of what sfCiti has accomplished with the 'Circle the Schools' program, which engages companies to enter into long-term partnerships with San Francisco public schools, using an adopt-a-school model.
